Ingres® Star (formerly Ingres Distributed Option) is a distributed data manager that adds to Ingres a distributed relational database management system capability, which includes distributed access, storage, and processing. You can include multiple hardware and operating systems (mainframe, mid-range, and desktop) and database management systems in this distributed system.

With Ingres Star, you can combine many separate databases into a single view of your data, which you can access just as you would any single, local database. If you install Ingres Net and the Enterprise Access products along with Ingres Star, you get transparent, simultaneous access across multiple nodes, hardware platforms, and software configurations by means of multiple network communication protocols.
