Final answer:
The MDB file format is a database file used by Microsoft Access, providing a means to create personal databases with tables, queries, forms, and more. It was the default format until Access 2007 and is suitable for desktop database applications.
Step-by-step explanation:
The MDB file format is a database file used by Microsoft Access, which is a desktop relational database management system (RDBMS) that combines the relational Microsoft Jet Database Engine with a graphical user interface and software development tools. The MDB format was the default file format used by Access up until the release of Access 2007, where it was succeeded by the ACCDB format.
This format allows for the creation of personal databases for storing information that can be analyzed and managed. An MDB file might contain tables, queries, forms, reports, macros, and modules. These files can be used for typical database applications but are most commonly associated with desktop applications rather than web or distributed applications.
