An embedded database, designed for use by a single application, runs on the same computer as the application and is generally hidden from the user.
When an application uses an embedded database, the personal server is generally not running when the application connects. The database is started using a connection string, and by specifying the database file in the DatabaseFile (DBF) parameter of the connection string.
To improve query performance for databases that are started automatically, start the database as soon as possible, even if users are not connecting right away. This allows the cache to warm before queries are executed against the database. See Cache warming.
