The Ado.NET Entity framework belongs to the .NET framework family and its main purpose is to extract the logical schema of the data and offer it in the form of conceptual schema to the application. It is a known fact that .net developers have to study a large amount of code and easing this problem is the Ado.Net entity framework. One of the main objectives is to help .Net application development capitalize on the advantages of the high level of abstraction that is needed for data programming thereby removing the mismatch that exists between languages and data models. The .NET developers are prevented from the dilemma of dealing with the confusion that the mismatch can create. The Entity Framework is available as part of the ADO.Net family of Microsoft dot net development platform.

In order to understand the role that Ado.Net entity framework plays and the platform that it offers to .Net development outsource companies, it is important to understand its architecture. The architecture of Ado.Net Entity framework comprises of various components and they include:

Specific Data Source Providers: The main function of this component is to abstract the Ado.Net interfaces thereby enabling .Net developers to connect it with the database when programming takes place against the conceptual scheme.

EDM Parser: This particular component along with view mapping picks up the SDL specification maps it onto the relational model and then facilitates programming against the conceptual model. Therefore, this helps .Net application development by assimilating information from multiple tables and then aggregating them into an independent entity.

Query and update: There is a query and update pipeline that helps in processing queries, it then filters and even updates requests to translate them into store specific queries through the help of the map provider.

Transactions and Metadata Services: Transactions help Microsoft dot net development to integrate with transactional abilities of the underlying store while metadata services helps in managing metadata in regard to relationships, entities and mappings.

Conceptual Layer API: This is the runtime that displays the programming model for coding and it helps .Net developers to use the ADO.Net for utilizing connection objects while referring to the map provider.

Disconnected Components: In the complete process of .Net application development, this helps in locally caching datasets and then utilizing Ado.Net entity framework in Entity Sets that contain the results.

Design Tools: .Net development outsource team also realizes that the Ado.Net framework also includes design tools such as mapping designer, which helps in easing the process of mapping a conceptual schema to the relational schema and also highlighting the characteristics of an entity type.
