Bridge Compass uses a database to store projects and its deals. The library patterns are also in that database. The settings from the option screen are stored in an ini-file that is next to the Bridge Compass database. Those are used at startup before the database is connected. The database is kept somewhere safe on your system. On the option screen and some database screens you can find its location. 

The database is an SQLite database. This is a very well known and often used SQL database. SQLite is in the public domain which means every can use it for free. Thanks to all the developers. It is not a multi-user database. This means you can't use it with more than one application/user at a time else you can get locking problems. 

The database menu on the menu bar looks like this:

It has three sections that will be discussed in the next topics:

  • Database maintenance
  • Library
  • Projects

Although we have tested it well and built some safeties, things can go wrong. Perhaps even you can make a mistake. So be a bit careful with these options.
