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.

Statement (I): The three phase (triple State/point) of a single component system possesses a single set of properties. Statement (II): For a single component system, the Gibbs phase rule, F = C + 2 - P (where F is number of independent intensive properties, C is number of components in the system and P is number of phases), reduces to F = 3 - P.
