Unlike many statistics programs, in SOFA Statistics you can connect directly to data you have in any supported SQL-type database (currently MS Access, MySQL, MS SQL Server, PostgreSQL, and SQLite).
NB if you have data in a spreadsheet or stored as csv see Importing spreadsheet/csv data
To connect to an SQL-type database, SOFA Statistics needs the necessary login details e.g. password. Rather than having to enter these repeatedly, you can store the login details as part of a project configuration. Most typically, you will only be wanting to connect to one database server e.g. MySQL. SOFA Statistics lets you store details for as many as you like e.g. if some of your data is in SQLite and some is in MS Access then you just enter connection login details for both.
