QDB databases use many files. Suppose that you want to create a database named customerdb and store its data in /usr/local/db/ and its schema definition files in your home directory of /home/user1/, and that you're using the default PPS configuration path (/pps/qnx/qdb/). You would need the following files to set up this database:
| File | Purpose |
|---|---|
| /pps/qnx/qdb/config/customerdb | Configuration object, stored as text file, containing paths to other setup files as well as policy settings such as auto-attached database preferences |
| /pps/qnx/qdb/status/customerdb | Status file created by QDB to indicate database state after attempted loading |
| /usr/local/db/customerdb | Raw SQLite file (created by QDB if necessary) that stores database content |
| /home/user1/customerdb.sql | Schema definition file that defines tables, views, indexes, and triggers that make up database |
| /home/user1/customerdb_data.sql | Data schema file that specifies initial data for populating database |
| /home/user1/customerdb_connect.sql | Client schema file that defines commands to execute when a client connects |
| /dev/qdb/customerdb | QDB device file used for publishing PPS objects |
