Microsoft access?

Some professional application developers use Access for rapid application development, especially for the creation of prototypes and standalone applications that serve as tools for on-the-road salesmen. Access does not scale well if data access is via a network, so applications that are used by more than a handful of people tend to rely on a Client-Server based solution such as Oracle, DB2, Microsoft SQL Server, PostgreSQL, MySQL, Alpha Five, MaxDB, or FileMaker. However, an Access "front end" (the forms, reports, queries and VB code) can be used against a host of database backends, including Access itself, Microsoft SQL Server, Oracle, and any other ODBC-compliant product.
