While the relational data management model has been known for some time, it has yet to be proven that such systems can perform efficiently in an industrial environment. This paper describes user experience with and the external highlights of the RElational General Information System (REGIS) which is currently being used within General Motors. This data analysis system combines the features of relational information handling along with graphical, interactive and statistical capabilities. REGIS provides the flexibility of handling unforeseen queries and enables the user to interactively analyze his data by entering commands from terminals. Its use does not require any conventional programming effort. It is possible to interface to user written functions if the need arises.
