You are creating an ASP.NET page for selling movie tickets. Users select a region, and then they select from a list of cities in that region. The site displays the names and locations of movie theaters in the city selected by the user. Your company, XYZ Brothers, maintains a list of theaters in a database table that includes the city, name, and street address of each theater. You want to minimize the time required to retrieve and display the list of theater names after a user selects the region and city. What should you do?
