After creating the domain knowledge, you can test it against the target database. Domain objects are saved in a .eqp file, or project file, and are translated automatically into a format required for communicating the domain to Microsoft English Query. This translated file is called a connection file (.eqc). The test component of English Query loads this connection file into the English Query engine, which enables you to test the English-to-SQL translation and the execution of the resulting SQL. Next, you compile the connection file into an English query application (.eqd).
