Explain EF Data access Architecture.

Answer»

There are TWO types of Data Access Architecture supported by the ADO.NET Framework: 

  • Disconnected data access: Disconnected data access is POSSIBLE with the Data ADAPTER object. Datasets work independently of databases, and the data can be edited.
  • Connected data access: A Data Reader object of a Data Provider allows you to access linked data. Data can be accessed quickly, but EDITING is not PERMITTED.
