ABSTRACT
Dot net dealt as a framework signifies the foundation for software development. The dot net framework consists of the common language runtime, which provides many of the core services required for program execution. This project includes the contents of dot net base class library, which exposes a set of pre-developed classes to facilitate program development. The common language specifications (CLS) defines a minimum set of standards that all language using the dot net frame work must support, and the common type system (CTS) ensures type compatibility between components developed in different languages.
A dot net executable is stored as a Microsoft intermediate language (MSIL) file. Here we have chosen the concept of disconnected architecture for our programming purpose, data set an in memory representation of the table and data tables objects independent of data adapters objects fill them programmatically. Data relation objects represent parent child relationship between columns of different tables .we used data relation objects to enforce constraints and retrieve related rows of data.
INTRODUCTION:
.NET Technology-
Microsoft's .NET technology is a technology intended to connect. What to connect? Well the whole thing that can be linked through software - people, structures, computers, and extra things as well as devices. .NET can grasp servers that offer web services or the tools wanted to generate these services.
What are Web Services and their profit? Well they can be called enhancements that assist businesses expand and connect by their clients and partners. Their profits are that they create the communication among business partners a lot easier and still increase the profits by creation a business known and accessible to much more people through the assist of the Internet.
A main part of the .Net technology and structure is the ASP.net set of technologies. These web development technologies are used in the making of Websites and net services working on the .NET infrastructure.
ASP.NET was build by Microsoft from one of their big technologies and web programmers can make use of any encoding language they want to write ASP.NET, from Perl to C Sharp (C#) and of course VB.NET and a few extra language unspoken with the .NET technology.
The advantages of the ASP.NET technology are that it creates construction Websites, Web applications and Web services very simple and with fewer code those older languages. As well, the applications compiled in ASP.NET run quicker and with fewer errors.
.NET Framework- -
The Microsoft .NET Framework is a software framework that can be installed on computers running Microsoft Windows operating systems. It includes a large library of coded solutions to prevent common programming problems and a virtual machine that manages the execution of programs written specifically for the framework. The .NET Framework is a key Microsoft offering and is intended to be used by most new applications created for the Windows platform.
The framework's Base Class Library provides a large range of features including user interface, data and data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. The class library is used by programmers, who combine it with their own code to produce applications.
Programs written for the .NET Framework execute in a software environment that manages the program's runtime requirements. Also part of the .NET Framework, this runtime environment is known as the Common Language Runtime (CLR).
C# Language
C# syntax is highly expressive, yet it is also simple and easy to learn. The curly-brace syntax of C# will be instantly recognizable to anyone familiar with C, C++ or Java. Developers who know any of these languages are typically able to begin to work productively in C# within a very short time. C# syntax simplifies many of the complexities of C++ and provides powerful features such as nullable value types, enumerations, delegates, lambda expressions and direct memory access, which are not found in Java. C# supports generic methods and types, which provide increased type safety and performance, and iterators, which enable implementers of collection classes to define custom iteration behaviors that are simple to use by client code. In C# 3.0, Language-Integrated Query (LINQ) expressions make the strongly-typed query a first-class language construct.
