The first time a application using Libgda is run, it creates a .libgda directory in the user's home directory to store the DSN definitions (in the .libgda/config file) and the dictionary files. This DSN refers to a sample SQLite database which is itself in the .libgda/sales_test file.
This DSN is installed to make it easy to run sample programs and get started quickly; it can be removed anytime whan not needed anymore (remove the entry in the .libgda/config file and the .libgda/sales_test itself).
The following diagram shows this small database's structure (as represented by the new experimental libgnomedb-goo library using the GooCanvas canvas) :
