Database/query files

This topic discusses how to use the Database Interface Designer when working with MDQ files to perform the following types of tasks:

• Create MDQ files and learn about their XML format. (For more information about the XML format, see Understanding the MDQ XML format.)
• Define the various objects included in an MDQ file. (For more information about such objects as queries and variables, see Defining a query and Defining Variables in SQL Statements.)
• Generate type trees. (See Generating type trees.)
• Print reports and enable trace functionality. (See Printing reports and Database Interface Designer trace files.)
