ABSTRACT OF TALK
Charlie Bachman, winner of the Alan M. Turing Award and Distinguished Fellow of the British Computer Society will describe the circumstances under which the first database management system (DBMS) came into being. The Integrated Data Store (IDS) was a unique assemblage of existing software technologies: virtual memory, blocked records, list processing, data descriptions, self identifying records, data manipulation language, recovery and restart, etc yielding an unprecedented result.

In 1960, General Electric was desperate to computerize their manufacturing systems, without each of 100 departments inventing their own solution. Charlie Bachman and other others from GE’s Corporate Services set out to solve the problem. By 1964 they had created and put into production a generic manufacturing system (MIACS), a transaction-oriented operating system, and the first database management system (IDS), all running a 8K GE 225 computer.

BACKGROUND OF SPEAKER
Charlie Bachman graduated with a BS in Mechanical Engineering (Tau Beta Phi) from Michigan State College in 1948 and an MS in Mechanical Engineering from the University of Pennsylvania in 1950.

He began working for Dow Chemical in Midland, Michigan in 1950. While there, he started the first computer department for business data processing and launched the SHARE 9PAC project for the IBM 709 computer. At the same time, Bachman pioneered the introduction of probability into the CPM/PERT scheduling that was used for Dow’s new plant construction.

In the early 60’s while working for GE his first assignment was to design and build a generic manufacturing information and control system (MIACS). The MIACS application system that came from this project contained many elements, which underlay most, current day, manufacturing control systems. The MIACS system also lead to the development of the first version of the Integrated Data Store (IDS) the database management system which was the basis for General Electric’s IDS and IDS II, Cullinet's IDMS and a host of other DBMS based on Bachman's Network Data Model. IDS was the first disk-based database management system used in every day production.

Bachman developed data structure diagrams (ER diagrams), commonly known as Bachman diagrams, as a graphical representation of semantic structures within the data.

On April 1, 1983 Bachman Information Systems, Inc. was created to productize the CASE (Computer Aided Software Engineering) concepts, which had been developed while at Honeywell and Cullinet. In 1991 the Company went public. In 1996 Bachman Information Systems, Inc. of Burlington, MA and Cadre Technology, Inc. of Providence, RI merged to form a new company, named Cayenne Software, Inc. Bachman’s IDS product and his CASE products are still alive under the CA banner.

Among his many honors and achievements, he was given the Alan M. Turing Award in 1973 for pioneering work in database management systems, elected a "Distinguished Fellow" of the British Computer Society in 1978 for database research and given a Life Achievement Award by the Massachusetts Software Council in 1996. He has been awarded more than twenty U.S. patents for database inventions and 1 British patent for pioneering work on model driven development (executable functional specifications).

Today, Bachman is a consultant living in Tucson, Arizona and is currently working on the story of the development of IDS.

DIRECTIONS
To Moffett Field/NASA Ames Research Park
From San Jose on 101 North or from San Francisco on 101 South, take the 2nd Moffett Exit (Moffett Field) to the guard gate at the main entrance to the NASA Ames Research Center.

From Highway 85 heading north, take the Moffett Boulevard exit. Turn right at the end of the ramp. Proceed to the guard gate at the main entrance to the NASA Ames Research Center.

To Moffett Training and Conference Center (Building 3)
After passing through the Guard Gate, proceed on Clark Road. Bear slightly left as the road forks onto South Akron Road along the open green of the Naval Reserve heading for NASA Hangar One. The Moffett Training and Conference Center is located on your left between Dugan Avenue and Severyns Avenue.

Parking is available in any of the surrounding lots.

To the Computer History Museum (Building 126)
From the guard gate, proceed straight ahead, keeping in the left lane. Bear slightly left as the road forks onto South Akron Road along the open green of the Naval Reserve heading for NASA Hangar One. One block before the hangar, turn right onto Severyns Avenue. Building 126 is on your left at the end of the block. Please look for the overhead sign indicating the Computer History Museum.
