Microsoft Enterprise Library Data Access Application Block simplifies development tasks that implement common data access functionality. Applications can use this application block in a variety of situations, such as reading data for display, passing data through application layers, and submitting changed data back to the database system. The application block includes support for both stored procedures and in-line SQL. Common application tasks, such as managing connections and creating and caching parameters, are encapsulated in the application block's methods.
The Data Access Application Block provides the following benefits:
It uses the functionality provided by ADO.NET 2.0 and with it, developer can use ADO.NET functionality along with the application block's functionality.
It reduces the need to write boilerplate code to perform standard tasks.
It helps maintain consistent data access practices, both within an application and across the enterprise.
It reduces difficulties in changing the database type.
It relieves developers from learning different programming models for different types of databases.
It reduces the amount of code that developers must write when they port applications to different types of databases.
