Ingres Corporation

Ingres Corporation was a pioneering American software company that developed and commercialized the INGRES relational database management system. Founded by University of California, Berkeley professor Michael Stonebraker, the company played a foundational role in the commercialization of relational database technology, competing directly with early offerings from Oracle Corporation and IBM. Its technology and intellectual property formed a critical lineage that influenced numerous subsequent database products and companies in the enterprise software market.

History

The company's origins trace directly to the groundbreaking INGRES research project initiated in the early 1970s at the University of California, Berkeley under the direction of Michael Stonebraker and Eugene Wong. This academic project, funded by agencies including the National Science Foundation and the United States Department of Defense, was instrumental in proving the practical viability of the relational model, a concept originally defined by Edgar F. Codd of IBM. In 1980, Stonebraker and several colleagues from Berkeley founded Relational Technology, Inc. to commercialize the INGRES software, which was later renamed. The company's early growth was fueled by the rising demand for Unix-based business applications, positioning it as a key rival to Oracle Corporation during the 1980s database wars. In 1990, the company was acquired by ASK Group, which was subsequently purchased by Computer Associates in 1994, where the database was marketed as CA-INGRES.

Products and services

The company's flagship product was the INGRES relational database management system, which included a comprehensive suite of tools for database development and administration. Its product portfolio expanded to include application development tools like INGRES/Windows 4GL and connectivity solutions such as INGRES/Net, facilitating client-server architectures. The company also offered professional consulting, technical support, and training services to its enterprise customers across various industries. Later versions incorporated object-relational capabilities and support for emerging Internet-based applications, maintaining its relevance in evolving IT landscapes.

Technology

The INGRES database was renowned for its innovative use of the QUEL query language, an alternative to the more dominant SQL pioneered by IBM. Its architecture featured a pioneering query optimizer and a rules-based system for integrity constraints, concepts that became standard in later database systems. Core technological components included the INGRES/Star distributed database manager, which allowed queries across multiple database servers, and the INGRES/Gateways for connectivity to other data sources. The codebase and core design principles directly influenced the development of PostgreSQL, as well as commercial products from Sybase and Microsoft SQL Server.

Business and market

The company initially targeted the technical and academic markets prevalent on Unix and VAX/VMS platforms, later expanding aggressively into the commercial enterprise sector. It engaged in intense competition with Oracle Corporation, IBM's DB2, and later Microsoft in the database market, with key battles over performance benchmarks and standards compliance. Its customer base included major organizations in telecommunications, manufacturing, and government, such as British Telecom and the United States Postal Service. The business model combined software licensing with recurring revenue from maintenance and support contracts, a standard practice in enterprise software.

Acquisitions and partnerships

To expand its technological footprint and market reach, the company acquired several smaller software firms, including the tools vendor Codex Corporation. A significant partnership was formed with Sun Microsystems to bundle and optimize the database for the SPARC server platform. Following its acquisition by Computer Associates, the technology was integrated into a broader portfolio of management software. In 2005, a management buyout backed by Garnett & Helfrich Capital separated the database assets from Computer Associates, rebranding them as Ingres Corporation before the assets were ultimately merged with other entities to form Actian.
