SQL Server : bcp Utility

Values in the data file being imported for computed or timestamp columns are ignored, and SQL Server 2000 automatically assigns values. If the data file does not contain values for the computed or timestamp columns in the table, use a format file to specify that the computed or timestamp columns in the table should be skipped when importing data; SQL Server automatically assigns values for the column.

Syntax

bcp {[[database_name.][owner].]{table_name | view_name} | "query"}

Study in UK : Procedure for get Admission in MBA/Post Graduation

Application forms will require details on completed academic records from the respective institutions or universities in English. All details regarding stream of specialization, details of the course and subjects, details of credits etc have to be kept in a sealed envelope and attested by the registrar.

Test such as IELTS (International English Language Test) conducted by the British Council is mandatory for all international students seeking admission to any university in the UK. Alternately TOEFL scores are accepted by most of the universities, few universities waive these tests if they are convinced that the student's medium of instruction has been English throughout.

To procure admission into any management course, GMAT scores are very essential; GRE scores are not considered for postgraduate courses in the UK.

Any work experience, very relevant for a MBA degree has to be submitted.

A letter of reference, preferably from a person who has taught you in the subject that is related to the course you are applying for will be essential. The positive and negative aspects, strength and weakness of the student should be listed and the author should strongly speak on why and how the student would excel in this particular stream of study. This letter speaks volumes in securing admission for a foreign student seeking admission in the UK.

A statement of purpose (SOP) given by the student should clearly speak on why he has chosen a particular stream of academics and how he will manage financially during the academic stay in the UK.

ISO 7816, EMV, and GSM

The International Standards Organization (ISO) developed the ISO 7816 standards for integrated circuit cards with contacts. These specifications focused on interoperability at the physical, electrical, and data-link protocol levels. In 1996, Europay, MasterCard, and VISA (EMV) defined an industry-specific smart card specification that adopted the ISO 7816 standards and defined some additional data types and encoding rules for use by the financial services industry. The European telecommunications industry also embraced the ISO 7816 standards for their Global System for Mobile Communications (GSM) smart card specification to enable identification and authentication of mobile phone users.

While all of these specifications (ISO 7816, EMV, and GSM) were a step in the right direction, each was either too low-level or application-specific to gain broad industry support. Application interoperability issues, such as device-independent APIs, developer tools, and resource sharing were not addressed by any of these specifications.

Windows System Assessment Tool (WinSAT)

The Windows System Assessment Tool (WinSAT) assesses the performance characteristics and capabilities of a computer. Developers can use this API to develop software that can access the performance and capability information of a computer to determine the optimal application settings based on that computer's performance capabilities.

Users can use the results of a formal assessment to determine which scenarios and applications will perform well on a computer. For example, if a software package contains a rating on its packaging, a user can use the rating to determine whether the software will run well on the computer.

SQL Server 2005 : What's New in ADO 2.6

ADO MD CubeDef.GetSchemaObject Method
ADO MD objects can now be retrieved using unique names, as specified by the UniqueName property. The names of parent objects do not need to be known, and parent collections do not need to be populated to retrieve a schema object. See GetSchemaObject Method.

ADOX Group and User Properties
ADOX Group and User objects now surface a Properties collection, which can be populated with provider-specific properties. Specifically, the OLEDB:Trustee PIN property can be specified.

Command Streams
The Command object supports commands in stream format as an alternative to using the CommandText property. The CommandStream property can be used to specify XML Templates or updategrams as the Command input with the Microsoft OLE DB Provider for SQL Server.

Dialect Property
Dialect is a new property that defines the syntax and general rules that the provider uses to parse the string or stream.

Execute Method (ADO Command)
The Execute method of the Command object has been enhanced to use streams for input and output.

Field Status
Values If the user encounters a DB_E_ERRORSOCCURRED error when modifying a Field of a Recordset, ADO will now fill the Field.Status property with the appropriate status information so that the user will have more information about what went wrong. See Status Property (ADO Field).

NamedParameters Property
NamedParameters is a new property of the Command object that indicates that the provider should use named parameters.

Resultsets in Streams
ADO can return resultsets from a data source in a Stream, rather than a Recordset object. Using the latest version of the Microsoft OLE DB Provider for SQL Server, you can get XML results from the provider by executing a "For XML" query. A Stream that receives the resultset can be opened with a "For XML" command as the source.

Single Row Resultset
The ADO Record object can now be opened on a command string or Command object that returns one row of data from the provider. This results in improved performance with MDAC 2.6 providers.

SQL Server 2005 : RDS.DataControl

This object can automatically invoke the RDS.DataSpace and
RDSServer.DataFactory objects. Use this object to invoke the default
RDS data retrieval or update behavior.

This object also provides the means for visual controls to access the
returned Recordset object.

SQL Server 2005 : RDSServer.DataFactory

RDSServer.DataFactory This object represents the default server program. It executes the default RDS data retrieval and update behavior.

SQL Server 2005 : class ID for the RDS.DataSpace object

BD96C556-65A3-11D0-983A-00C04FC29E36.

DataSpace Object (RDS) RDS.DataSpace

Creates client-side proxies to custom business objects located on the middle tier.

Remote Data Service needs business object proxies so that client-side components can communicate with business objects located on the middle tier. Proxies facilitate the packaging, unpackaging, and transport (marshaling) of the application's Recordset data across process or
machine boundaries.

Remote Data Service uses the RDS.DataSpace object's CreateObject method to create business object proxies. The business object proxy is dynamically created whenever an instance of its middle-tier business object counterpart is created. Remote Data Service supports the following protocols: HTTP, HTTPS (HTTP Secure Sockets), DCOM, and in-process (client components and the business object reside on the same computer).

Basic RDS Programming Model

RDS addresses applications that exist in the following environment: A client application specifies a program that will execute on a server and the parameters required to return the desired information. The program invoked on the server gains access to the specified data source, retrieves the information, optionally processes the data, and then returns the resulting information to your client application in a form that it can easily use. RDS provides the means for you to perform the following sequence of actions:

Specify the program to be invoked on the server, and obtain a way to refer to it from the client. (This reference is sometimes called a proxy. It represents the remote server program. The client application will "call" the proxy as if it were a local program, but it actually invokes the remote server program.)
Invoke the server program. Pass parameters to the server program that identify the data source and the command to issue. (The server program actually uses ADO to gain access to the data source. ADO makes a connection with one of the given parameters, and then issues the command specified in the other parameter.)
The server program obtains a Recordset object from the data source. Optionally, the Recordset object is processed on the server.
The server program returns the final Recordset object to the client application.
On the client, the Recordset object is put into a form that can be easily used by visual controls.
Any modifications to the Recordset object are sent back to the server program, which uses them to update the data source.

SQL Server 2005 : Use of MDAC Version 2.6

The Microsoft Data Access Components (MDAC) SDK documents the key
technologies that enable Universal Data Access, Microsoft's strategy
for providing access to information across the enterprise.

Microsoft Data Access Components include ActiveX Data Objects (ADO),
OLE DB, and Open Database Connectivity (ODBC). Data-driven
client/server applications deployed over the Web or a LAN can use
these components to easily integrate information from a variety of
sources, both relational (SQL) and nonrelational.

The MDAC SDK is the primary source of information and instruction for
using data access technologies. Its tools, samples, and documentation
are designed to help developers create solutions for their data access
needs.

How to call the superclass constructor?

If a class called “SpecialClass1” extends your “Class1” class then you can
use the keyword “super” to invoke the superclass’s constructor. E.g.
public SpecialClass1(int id) {
super(id); //must be the very first statement in the constructor.
}
To call a regular method in the super class use: “super.myMethod( );”.

Java :Call one constructor from another?

Yes,
by using this() syntax. E.g.

public class1(int id) {
this.id = id; // “this” means this object
public class1 (int id, String type) {
this(id); // calls constructor public class1(int id)
this.type = type; // ”this” means this object

Jave :Whar are “static initializers” or “static blocks with no function names”?

When a class is loaded, all blocks that are declared static and don’t have function name (i.e. static initializers) are executed even before theconstructors are executed. As the name suggests they are typically used to initialize static fields.

public class StaticInitializer {
public static final int A = 5;
public static final int B; //note that it is not public static final int B = null;
//note that since B is final, it can be initialized only once.
//Static initializer block, which is executed only once when the class is loaded.
static {
if(A == 5)
B = 10;
else
B = 5;
public StaticInitializer(){} //constructor is called only after static initializer block

The following code gives an Output of A=5, B=10.

public class Test {
System.out.println("A =" + StaticInitializer.A + ", B =" + StaticInitializer.B);

Java : Explain static vs. dynamic class loading?

Static class loading
Classes are statically loaded with Java’s“new” operator.
class MyClass {
public static void main(String args[]) {
Car c = new Car();
}
}

Dynamic class loading
Dynamic loading is a technique for programmatically invoking the functions of a class loader at run time. Let us look at how to load classes dynamically.Class.forName (String className); //static method which returns a Class The above static method returns the class object associated with the class name. The string className can be supplied dynamically at run time. Unlike the static loading, the dynamic loading will decide whether to load the class Car or the class Jeep at runtime based on a properties file and/or other runtime conditions. Once the class is dynamically loaded the following method returns an instance of the loaded class. It’s just like creating a class object with noarguments.

class.newInstance (); //A non-static method, which creates an instance of a
//class (i.e. creates an object).

What are the usages of Java packages?

It helps resolve naming conflicts when different packages have classes with the same names. This also helps you organize files within your project. For example: java.io package do something related to I/O and java.net package do something to do with network and so on.

What is the difference between C++ and Java?

Both C++ and Java use similar syntax and are Object Oriented, but:Java does not support pointers. Pointers are inherently tricky to use and troublesome.

Java does not support multiple inheritances because it causes more problems than it solves. Instead Java supports multiple interface inheritance, which allows an object to inherit many method signatures from different interfaces with the condition that the inheriting object must implement those inherited methods. The multiple interface inheritance also allows an object to behave polymorphically on those methods.

Java does not support destructors but adds a finalize() method. Finalize methods are invoked by the garbage collector prior to reclaiming the memory occupied by the object, which has the finalize() method. This means you do not know when the objects are going to be finalized. Avoid using finalize() method to release nonmemory
resources like file handles, sockets, database connections etc because Java has only a finite number of these resources and you do not know when the garbage collection is going to kick in to release these resources through the finalize() method.

Java does not include structures or unions because the traditional data structures are implemented as an object oriented framework.

All the code in Java program is encapsulated within classes therefore Java does not have global variables or functions.
C++ requires explicit memory management, while Java includes automatic garbage collection.

What is Network Time Protocol (NTP)?

The Network Time Protocol (NTP) is a protocol for distributing the
universal time (UTC) by means of synchronizing the clocks of computer
systems over packet-switched, variable-latency data networks. NTP uses
UDP port 123 as its transport layer. It is designed particularly to
resist the effects of variable latency by using a jitter buffer.

What is Marshalling ?

Marshalling (similar to serialization) is the process of transforming the memory representation of an object to a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another.

What is Distributed Transaction Coordinator (MSDTC) ?

The Distributed Transaction Coordinator (MSDTC) service is a component
of modern versions of Microsoft Windows that is responsible for
coordinating transactions that span multiple resource managers, such
as databases, message queues, and file systems. MSDTC is included in
Windows 2000 and later operating systems

What is Microsoft Message Queuing (MSMQ )?

MSMQ is essentially a messaging protocol that allows applications running on disparate servers to communicate in a failsafe manner. A queue is a temporary storage location from which messages can be sent when conditions permit. This enables communication across heterogeneous networks and between computers which may not always be connected.

Flex 3 new features

Native support for Adobe AIR – Flex 3 introduces new components and incorporates the Adobe AIR development tools into the SDK and Flex Builder.
Persistent framework caching – You can make Flex 3 applications as small as 50K when leveraging the new Flash Player cache for Adobe platform components.
Flex Builder productivity enhancements – Flex Builder 3 introduces refactoring support, new profilers for performance and memory tuning, and code generation tools for data access.
Integration with Creative Suite 3 – The Flex Component Kit for Flash CS3 allows Flash CS3 users to build components that can be seamlessly integrated into a Flex application, while Flex Builder 3 adds new wizards for importing assets from CS3 applications as skins.
Advanced DataGrid – The Advanced DataGrid is a new component that adds commonly requested features to the DataGrid such as support for hierarchical data, and basic pivot table functionality.
First steps toward open source Flex. As a first step toward making Flex an open source project, we've opened up the Flex and Flex Builder bug tracking system to the public, as well as published detailed roadmap information.

Flash Flex 3 :SpringGraph amazing tree visualization tool

Mark Shepherd has put together an amazing tree visualization tool called SpringGraph (http://mark-shepherd.com/Spring Graph/).

Flash Flex 3 :Distortion Effects

Alex Uhlmann (http://alex-uhlmann.de/flash/animationpack age/) has developed a set of distortion effects to supplement the effects provided in the Flex core.

Flash Flex 3 :FlexLib Project

The FlexLib Project (http://flexlib.googlecode.com/) is an open source set of containers, controls, and classes to which you are free to contribute. The FlexLib Project comprises a wide variety of controls, including a horizontal accordion, advanced sliders and tab bars, and enhanced tree controls, among others.

Flex 3 :Advanced Flash Components

Flex is built on top of Flash, so you can use Flash components in your Flex application directly. This allows you to use a wide variety of off-the-shelf Flash components, including the Flash components available from Advanced Flash Components (AFC; http://www.afcomponents.com/).

Flash Flex Builder : ILOG Elixir

ILOG Visualization Products has developed a set of extremely powerful data visualization controls designed specifically for Flex. The ILOG Elixir toolkit (http://www.ilog.com/products/
elixir/) contains a complete set of 2D and 3D graph types, all of which allow you to create effects-based transitions that will make you look like a superstar. Included in the toolkit are
ready-to-use schedule displays, map displays, dials, gauges, 3D and radar charts, Gantt charts, a treemap chart, and organization charts.

JSP : Life Cycle of a Servlet

The javax.servlet.Servlet interface defines the methods that all servlets must implement and among others, three methods that are known as life-cycle methods:

public void init(ServletConfig config) throws ServletException
public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException
public void destroy()

These life-cycle methods are each called at separate times during the lifespan of a servlet, from the initial creation to the moment it's removed from service and destroyed. These methods are called in the following order:

1. When the servlet is constructed, it is initialized with the init() method.
2. Any requests from clients are handled initially by the service() method before delegating to the doXxx() methods in the case of an HttpServlet. This method is responsible for processing the request and returning the response.
3. When the servlet needs to be removed from service, it's destroyed with the destroy() method, then garbage collected and finalized. When the container decides to take a servlet out of service it first ensures that any service() method calls have completed.

JSP :ServletInputStream and ServletOutputStream abstract classes

The ServletInputStream and ServletOutputStream abstract classes provide the ability to read and write binary data from and to the client. Implementations of these classes must provide an implementation of the java.io.InputStream.read() and java.io.OutputStream.write() methods, respectively.

JSP : GenericServlet abstract class

The GenericServlet abstract class can be used to develop protocol-independent servlets and requires only that subclasses implement its service() method.

JSP : javax.servlet Interfaces

The javax.servlet package is composed of twelve interfaces. The web container implements seven of these interfaces as follows:
ServletContext
ServletConfig
ServletResponse
ServletRequest
RequestDispatcher
FilterChain
FilterConfig

JSP : exception object

Exception object is only available to those JSP pages that declare themselves as error pages
using the following page directive
<%@ page isErrorPage="true" %>

JSP : config object

The config object simply provides the JSP developer with access to the ServletConfig object that is used by the web container to configure the JSP and its implementation servlet. The ServletConfig interface is most commonly used to provide access to any initialization parameters that have been configured for either the JSP or its implementation servlet via the deployment descriptor of the web application.

JSP : out object

The implicit out object represents an instance of the javax.servlet.jsp.JspWriter class that can be used to write character data to the response stream in a similar manner to that seen by the java.io.PrintWriter class.

JSP : Instance of the javax.servlet.http.HttpServletResponse interface

response object

JSP Request Object

The request object provides access to all of the available information about the user request such as request parameters and headers and may be used in exactly the same way as the HttpServletRequest parameter is used in the service() method of a normal servlet.

which is an instance of the javax.servlet.http.ServletRequest interface

JSP 2.0, for the first time, introduces an EL based on both ECMAScript and XPath, which has been designed to be simple to use and more user-friendly than Java.

The new EL has built-in support for JavaBean access and manipulation, collections of objects, and automatic type conversion to name but a small part of its extensive feature list. If you're familiar with JavaScript you should have no problem understanding the syntax of the EL, which insists that all expressions must be enclosed within ${ and } delimiters.

JSP Page :Template Text

Any non-JSP code located inside a JSP page is known as template text. Template text can take any form aslong as it's text based. The most common form of template text is markup such as HTML or XML. For example, if your web design team was to develop an HTML page that you were required to convert into aJSP page in order to add some form of dynamic processing, then all of the HTML markup would be referred to as template text:

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ page import="com.Calendar"%>
<html>
<head>
<title>My HTML Example</title>
</head>
<body>
<jsp:useBean id="cal" class="com.Calendar"/>
<c:set var="hour" value="${cal.hour}" scope="request" />
<c:choose>
<c:when test="${hour > 0 && hour <=11}">
Good Morning!
</c:when>
<c:when test="${hour >= 12 && hour <=17}">
Good Afternoon!
</c:when>
<c:otherwise>
Good Evening!
</c:otherwise>
</c:choose
</body>
</html>

JSP Page : Security Problems

As each JSP page is responsible for handling all of its processing, it's possible that any actions that require a user to be logged in or that access password-protected resources such as databases, could end up exposing sensitive information by embedding it in the page. It's therefore important to make sure that any such logic is encapsulated into JavaBean components or custom actions to prevent this possible security hole.

JSP Page : Reusability Problems

When most of the processing logic is embedded into the JSP pages, it becomes much more difficult to reuse common functionality because it's usually implemented using scriptlets. Often this results in a lot of cutting and pasting of code that isn't only bad from a reusability perspective but is also likely to introduce errors and decrease productivity.

JSP Page Maintainability Problems

Because each JSP page is solely responsible for handling a client request, it will often have to directly interact with a business layer. This can result in the application structure being embodied within the pages themselves. This obviously makes the pages more complicated and more likely to contain lots of scriptlet code, which ultimately makes them far harder to maintain.

JSP : Readability

Embedding too much Java code in the page can easily lead to pages that are unreadable as content (typically HTML) is mixed with JSP tags and Java code wrapped up as scriptlets. In addition to the confusion caused by the various syntaxes that each of these "languages" uses, one clear problem with embedding Java code inside JSP pages is that it's hard to correctly indent your source code. Writing and indenting code is trivial when dealing with regular class files, but trying to correctly indent Java code that is mixed up with HTML and JSP is a different story.

What does it take to succeed in a role like this?

This question will help you achieve two things. First, it will help you understand the standards your boss expects you to meet. Second, you will come across as someone who is keen on succeeding. You must also ask how success is measures in the team as it depends on a boss's managerial style. For instance, if it's a sales oriented position, will you be rewarded only for exceeding sales, or are there rewards for customer satisfaction, teamwork etc? Try and get specific answers from the employer, as this will be an indication of where you should focus your energies if you intend to take up the job.

What are your key expectations from team members?

Often, as an answer to this question, most supervisors start by describing traits demonstrated by their favourite employees in the team. This can be a great clue to understanding what it is going to take to get into your boss's good books. If your boss-to-be says he wants team members to take initiative and perform independently, you know he is not going to micromanage and breathe down your neck everyday. If he says that they expect team members to 'go the extra mile' and work hard, you will spoil your impression by trying to sneak out of office early every day.

Oracle 9i Index-Organized Tables IOT

An Index-Organized Table (IOT) is a unique storage organization feature of the Oracle9i server that provides added value in performance, scalability, and availability over conventional tables. The actual data for an index-organized table is stored in B-tree index leaves in sorted order based on the table's primary key so that changes to that data, such as adding, updating, or deleting rows, require an update t o the index only. This approach enables extremely fast access to table data for primary key based queries, making index-organized tables ideal for a wide variety of applications.

new feature in ADO.NET version 2.0 :SqlBulkCopy

ADO.NET (ActiveX Data Object) is a set of classes used for data access in .NET. ADO allows .NET programmers to access a database without even

knowing how the database has been implemented. It is a part of base class library that is included with the Microsoft .NET Framework.
The simplest and fastest way of copying a large amount of data from different sources to an SQL Server table can be accomplished with the help of Bulk Copy Operation, a new feature in ADO.NET version 2.0.

Here different sources of data are those from which data can be loaded into 'DataTable' instance or read with 'IDataReader' instance. To accomplish bulk copy one has to use 'SqlBulkCopy' class that is present in 'Sytem.Data.SqlClient' namespace in .NET framework. Now using this 'SqlBulkCopy' class one can perform single bulk copy, multiple bulk copy and bulk copy with a transaction.

using System.Data.SqlClient;
string connectionString = "Data Source=.;Initial Catalog=NTL;User ID=sa;Password=P@ssw0rd";
SqlConnection sourceConnection = new SqlConnection(connectionString);
sourceConnection.Open();

SqlCommand commandSourceData = new SqlCommand("SELECT * FROM Source;", sourceConnection);
SqlDataReader reader = commandSourceData.ExecuteReader();
Connect to a destination table of data using:
SqlConnection destinationConnection = new SqlConnection(connectionString);
destinationConnection.Open();

SqlBulkCopy bulkCopy = new SqlBulkCopy(destinationConnection);
bulkCopy.DestinationTableName = "Destination";
bulkCopy.WriteToServer(reader);
reader.Close();

Mirrored storage arrays

Because of the increased risks of natural and man-made disasters, each organization has their own disaster recovery plans. Most of the organizations keep a backup of their data on tapes in a remote location. But since transportation of these tapes from one place to another and then loading them on to an alternate server to bring the data online consumes hell lot of time. For faster disaster recovery, a live secondary server site which has a replica of the production data at the primary site is required and this is what Storage mirroring technology makes possible. Here, two storage systems kept at a large distance from each other transparently send data packets to each other and in the event of a disaster at one site, the other site can take over almost instantaneously because it has the most recent copy of whole of the critical data. Since the mirroring is done by the storage system, it does not add any additional load to the data center servers in this process. There have been some dramatic improvements in reliability and disaster readiness because of this technology.

IP SAN

When Storage Area Networks appeared in the market, they were seen as an expensive storage solution, which only a large data center could afford. But the speed of access and the security provided by SANs made them an attractive choice for large data centers.

Then came IP SAN, a Storage Area Network implemented using the Internet SCSI (iSCSI) protocol. IP SANs provide all the benefits of SAN (security, speed and scalability) but at a lower cost as the ISCSI uses regular Ethernet adapters, cables and switches for storage-server connectivity. Thus the organization adopting IP SAN can use the existing local area networks for dual purposes; for data and storage connectivity. In fact, since this technology is based on IP standards, so one can easily connect remote offices over the WAN, using IP protocols, into the central data centre for consolidation and back-up of data.

Thin provisioning

Storage users generally over-estimate their disk space requirements as they have very little idea about how their requirement will grow over time. So each user tends to keep a little 'buffer' in their storage capacity estimates and this adds on to a huge storage capacity out of which only less than half the storage capacity gets consumed. For whole of the storage capacity the organizations pay a huge sum and if they are paying for something which they are not even using then it is a drawback. To avoid this one can use thin provisioning; this dramatically improves the storage capacity utilization within an organization and thereby reduces costs significantly.

Teredo Tunneling

NAT has been used to overcome ipv4 address shortage as it acts as an interface between Internet and the local network. It translates private address of local network to the public address of ISP. Now that ipv6 is a reality, overcoming the ipv4 to ipv6 transition is an important issue. This issue was resolved to certain extent by 6to4 protocol, that could be implemented on NAS.
Teredo Tunneling is a protocol that gives ipv6 connectivity to nodes that connect through NAT devices that do not understand ipv6. In this protocol, ipv6 packets are encapsulated into ipv4 UDP datagrams that can route through NAT and ipv4 Internet. Teredo was introduced because 6to4 protocol, that is most common ipv6 over ipv4 protocol, was economically and technically difficult to implement on most NAT devices. Teredo in turn is implemented on nodes itself that can easily understand the encapsulated packets and thus gain ipv6 connectivity without NAT being ipv6 aware.
