What is .Net Technology?
Web Developer produce software by combining their own source code with .NET Framework and other libraries. Or we can say
A new software platform for the desktop and the Web operating system (Windows, Linux, Unix,)
Microsoft .NET is a Framework which provides a common platform to Execute or, Run the applications developed in various programming languages.
In .Net there are some basic and important concepts:
. NET Framework:
. NET Framework is intended to be used by most new applications created for the Windows platform. Microsoft also produces an integrated development environment largely for .NET software called Visual Studio.
Provide environment for developing various types of applications, such as Windows-based applications and Web-based applications.
To ensure that code based on the .NET Framework can integrate with any other code.
The .NET Framework consists of:
The Common Language Specification (CLS)
It contains guidelines that language should follow so that they can communicate with other .NET languages. It is also responsible for Type matching.
The Framework Base Class Libraries (BCL)
A consistent, object-oriented library of prepackaged functionality and Applications.
The Common Language Runtime (CLR)
A language-neutral development & execution environment that provides common runtime for application execution.
Defines rules that languages must follow, which helps ensure that objects written in different languages can interact with each other
ADO.Net
ADO.NET provides a bridge between the front end controls and the back end database. The ADO.NET objects encapsulate all the data access operations and the controls interact with these objects to display data, thus hiding the details of movement of data.
Dataset
The Dataset object is central to supporting disconnected, distributed data scenarios with ADO.NET. The Dataset is a memory-resident representation of data that provides a consistent relational programming model regardless of the data source.
The Dataset represents a complete set of data, including related tables, constraints, and relationships among the tables. The following illustration shows the Dataset object model.
Data Reader
A Data Reader is an object returned from the Execute Reader method of a DB Command object.
Data Table
Data Table is an in-memory representation of a single database table which has collection of rows and columns. .Data Table fetches only one Table Row at a time Dataset: .A Dataset is an in-memory representation of a database-like structure which has collection of Data Tables.
