what is microsoft access ?

Microsoft Access (current full name Microsoft Office Access) is a relational database management system from Microsoft, packaged with Microsoft Office Professional which combines the relational Microsoft Jet Database Engine with a graphical user interface.

Microsoft Access can use data stored in Access/Jet, Microsoft SQL Server, Oracle, or any ODBC-compliant data container. Skilled software developers and data architects use it to develop application software. Relatively unskilled programmers and non-programmer "power users" can use it to build simple applications. It supports some object-oriented (OO) techniques but falls short of being a fully OO development tool.

Microsoft Access was also the name of a communications program from Microsoft, meant to compete with ProComm and other programs. This Microsoft Access proved a failure and was dropped. Years later Microsoft reused the name for its database software.
