Ability Database (ADB) is the native format of the Database program in the Ability Office suite, though this program also supports the Microsoft Access (MDB) format.
Ability Database is a relational database supporting SQL queries, similar to a number of other database engines. The presence of the string "Standard Jet DB" in the file headers indicates the possibility that this format is derived from the Jet format on which MS Access was also based.
