Abstract

Effective management of projects is vital for the development of economy because development itself is the effect of series of successful managed projects. This makes project management extremely important problem area for developing economy such as ours. Unfortunately many projects experience schedule slippage and cost overruns due to variety of reasons. To remedy the situation, a project has to be meticulously planned, effectively implemented and professionally managed to achieve the objective of the time, cost and performance. Computerization of the project management can play a major role in streamlining the management of project. Thus we see the computer becoming necessity in the day to day life. The use of computer also involves the feeling of healthy competition with the organization receiving much attention these days. Almost everyday uses of paper carry advertisements asking for project managers. The scenario was not so bright a few years back. For that matter even today thou

INTRODUCTION TO C#

 

Let’s look at the key building blocks of .NET and some related technologies.

 

• C#, a new language

 

C# is the first component oriented language in the C and C++ family of languages. It is a simple, modern, object oriented and type- safe programming language derived from C and C++. C# combines the high productivity of Microsoft Visual Basic and the raw power of C++.

 

• Common language runtime

 

The high performance common language runtime includes as execution engine, a garbage collector, post in time compilation, a security system, and a rich class framework (the .NET Framework). The runtime was designed from the ground up to support multiple languages.

 

• Common language Specification

 

The Common Language Specification (CLS) describes a common level of language functionality. The relatively high minimum bar of the CLS enables the creation of  a club of CLS compliant languages. Each member of the club enjoys dual benefit: complete access to .NET functionality and rich interoperability with other compliant languages. For  e.g. a Visual Basic class can inherit from a C# class and override its virtual methods.

 

• A Rich  Set  Of  Languages That  Target  The  Runtime

 

Microsoft provided languages that target the runtime include Visual Basic, Visual C++ with Managed Extensions,

Visual C# and J Script. Third parties are providing many other languages- too many to list he

 

 

LANGUAGES USED

Why .NET?

 

1. Interoperability between languages and execution environments
2. Uniformity in schema or formats for Data Exchange using XML, XSL
3. Extend or use existing code that is valid
4. Programming complexity of environment is reduced

 

 

The .NET Framework is…

 

1. A component model for the internet
2. The new approach to building large scale distributed systems for the Internet
3. Provides the capability to integrate multiple devices
4. Built around the tools and protocols (XML, WSDL, SOAP, HTTP) that are becoming standard on the Internet

 

The .NET in ASP.NET stands for the .NET Framework, a set of objects and blueprints from Microsoft for building applications. All applications developed under the .NET Framework; including ASP.NET applications, have certain key features that ensure compatibility, security, and stability.

Common Language Runtime (CLR) is an environment that manages the execution of code. With the .NET Framework and CLR, we write code and compile it. However, instead of compiling it into the computer understands, we compile it into a language called Microsoft Intermediate Language (MSIL). When we compile to MSIL, your application produce something called metadata. This is descriptive information about your application. It tells what the application can do, where it belongs, and so on. When you want to run your program, the CLR takes over and compile the code once more into the computer’s native language. This way MSIL can go on any type of computer. The CLR can speak many different computer languages and does all the compiling for you. Once you compile your application, you can bring it to any other computer. CLR also provides services such as error handling, security features, versioning and deployment support, as well as cross-language integration. That means we can choose any language we want to write our .NET applications, including ASP.NET applications.

 

The .NET Framework Design Goals

1.       Component Development for the Internet
2.      “Cross-Language Development”
3.        Inheritance, Debugging, Exception handling
4.        Reliability and Security
5.        Simple Development and Deployment
6.         Device-agnostic

ASP.NET:

ASP.NET is a technology that allows us to build and control dynamic Web pages easily. It also provides many enhancements to take advantage of new technology as we can interact with databases, personalize Web pages for visitors, display page on mobile devices (such as cell phones), and even build an entire e-commerce site from scratch.

Previously internet works on request/response model that is an integral part of client/server model. Although this is a marvelous way of communicate and distribute information, it’s rather simple and static. When the process is over, once client receives the requesting page from the server the server has no idea what the client is doing unless it makes another request.

There is another model for communicating between server and clients, known as event-driven model.ASP.NET work on this model, it detects action and responds to them i.e. the server waits around for something to happen on the client. Once it does, the server takes action and performs some piece of functionality. Of course, a Web, server can not know what you are thinking, but it can respond to your actions. If you type some text on Web page, the server responds to it. If you click an image, the server responds.

COMPARISON OF ASP AND ASP.NET:

 

• Classic ASP was built on the top of the Windows operating system and IIS (Internet Information Server). It was always a separate entity, and therefore its functionality was limited. ASP.NET, on the other hand, is an integral part of the system under the .NET Framework. It shares many 9f the same objects that traditional applications would use and all .NET objects available for ASP. NET’s consumption.
• Instead of being limited to six inherent objects in ASP, ASP.NET has a plethora of useful components it can build form.
• ASP also made it abundantly clear that client and server were two separate entities, Whereas ASP. NET ties together the client and the server through clever use of server-side and client-side code, all invisible to the developer.
• NET code is compiled, whereas classic ASP used interpreted scripting languages. Using compiled code means an automatic boost in performance over ASP applications.
• In classic ASP, nearly all of the code was executed in code render blocks (that is, inside <%…%> tags). In ASP.NET, this type of code isn’t compiled and isn’t recommended for frequent use. Instead, you use the code declaration blocks, which are compiled and provide better performance.

Following are some of the significant new features of ASP.NET:

• NET uses compiled code written in Common Language Runtime languages such as Visual Basic and C#. Unlike previous versions of Active Server Pages, this version does not use interpreted scripting languages such as VBScript.
• NET pages are built out of server-side controls. Web server controls enable you to represent and program against Hypertext Markup Language (HTML) elements using an intuitive object model.
• NET includes a new technology called Web Services. You can use Web Services to access methods and properties and transfer database data across the Internet.

 

DBMS

 

SQL SERVER: ­

SQL Server is an SQL-compliant RDBMS. SQL-compliant means it use the ANSI (American National Standard Institute) version of Structured Query Language or ‘SQL’. Structured Query Language is a command that allow us to modify or retrieve information from the database.

CLIENT SERVER MEANS THAT SQL SERVER IS DESIGNED TO STORE DATA IN THE CENTRAL LOCATION (THE SERVER) AND DELIVER IT ON DEMAND TO NUMEROUS OTHER LOCATIONS (THE CLIENT). SQL SERVER IS ALSO A RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS).

 

FEATURES OF SQL SERVER 2005:­

• Information representation
• Unique definition of rows
• Systematic treatment of Null values
• Guaranteed access
• High level Update, Insert, and Delete
• Retrieving information from the database.
• Accepting query language statements.
• Enforcing security specifications.
• Enforcing data integrity specifications
• Enforcing transaction consistency
• Managing data sharing
• Optimizing queries
