You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.

P :But it is the conflict between the massive scope for progress provided by digital era and the fear of loss of individual autonomy that is foregrounded in any debates about data protection laws.

You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
