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.
Which code segment should you use?

You are a developer for a XYZ Inc that provides free software over the Internet. You are developing en e-mail application that users all over the world can download.

The application displays text strings in the user interface. At run time, these text strings must appear in the language that is appropriate to the locale setting of the computer running the application.

You have resources to develop versions of the application for only four different cultures.You must ensure that your application will also be usable by people of other cultures.
How should you prepare the application for deployment?

You use Visual Studio .NET to develop a Windows-based application that interacts with a Microsoft SQL Server database. Your application contains a form named CustomerForm.

 You add the following design-time components to the form:

• SqlConnection object named XYZConnection.
• SqlDataAdapter object named XYZDataAdapter.
• DataSet object named XYZDataSet.
• Five TextBox controls to hold the values exposed by XYZDataSet.

At design time, you set the DataBindings properties of each TextBox control to the appropriate column in the DataTable object of XYZDataSet. When you test the application, you can successfully connect to the database. However, no data is displayed in any text boxes.

You need to modify your application code to ensure that data is displayed appropriately. Which behavior should occur while the CustomerForm.Load event handler is running?

If there is a lock on an adjacent key, an insert will fail if the isolation level is set to what?

Which of the following tools can be used to identify inefficient SQL statements without executing them?
