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" .)
