MS ACCESS stores data in its own format in an Access Jet-based database engine. It can also directly import or link data stored in other applications and databases.
Software developers and data architects can use Microsoft Access to develop application software, and "power users" can use it to build software applications. Like other office applications, ACCESS supports the Visual Basic macro language, which is 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 are used to display tables and reports. Their methods and properties are in the VBA programming environment. VBA code modules can declare and call Windows operating system functions.
