Microsoft Office Access, member of the Microsoft Office suite of applications, is a relational database management system that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools.Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.

Developers and data architects can use Microsoft Access to develop application software, and “power users” can use it to build simple applications. Like other Office applications, Access is supported by VBA (Visual Basic for Applications), an object-oriented programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating-system function.
