Integrated Data Store (IDS) is a network database largely used by industry for its performance.
IDS was designed by Charles Bachman at General Electric in the 1960s. It was not easy to use or implement applications with IDS, because it was designed to maximize performance using the hardware available at that time. However, that weakness was equally its strength because present-day skilful implementations of IDS-type databases, such as British Telecom's huge CSS project (an IDMS database servicing 10 Billion+ Transactions per Year), show levels of performance on terabyte-sized databases that are unmatchable by all relational database implementations. Charles Bachman's brilliantly innovative design work continues to find state-of-the-art application with major commercial operations.
