MDB file extension - Microsoft Access database

What is mdb file? How to open mdb files?

The mdb file extension is associated with Microsoft Access. Microsoft Access is a database management system, part of Microsoft Office Suite, developed by Microsoft Corporation.

The mdb files were used by Microsoft Access prior version 2007 for its main database files. The latest versions of Microsoft Access are using the accdb files for databases instead.

Access stores data in its own format based on the Access Jet Database Engine. The mdb file contains database structure and database entries (tables, fields, table rows).

It can also import or link directly to data stored in other Access databases, Excel, SharePoint lists, text, XML, Outlook, HTML, dBase, Paradox, Lotus 1-2-3, or any ODBC-compliant data container including Microsoft SQL Server, Oracle, MySQL and PostgreSQL.

Software developers and data architects can use it to develop application software and non-programmer "power users" can use it to build simple applications. It supports some object-oriented techniques but falls short of being a fully object-oriented development tool.

Some other applications can also utilize the mdb file format for its database files, such as AutoCAD Civil.
