Integrated Data Store
Integrated Data Store (IDS) was an early network database management system largely used by industry, known for its high performance. IDS became the basis for the CODASYL Data Base Task Group standards. IDS was designed in the 1960s at the computer division of General Electric (which later became Honeywell Information Systems) by Charles Bachman, who received the Turing Award from the Association for Computing Machinery for its creation, in 1973. The software was released in 1964 for the GE 235 computer. By 1965, a network version for the customer Weyerhaeuser Lumber was in operation. IDS/II, introduced in 1975, was a . At this time the original version was labeled IDS/I. 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 skilful implementations of IDS-type databases, such as British Telecom's huge CSS project (an IDM ...

Charles Bachman
Charles William Bachman III (December 11, 1924 – July 13, 2017) was an American computer scientist, who spent his entire career as an industrial researcher, developer, and manager rather than in academia. He was particularly known for his work in the early development of database management systems. His techniques of layered architecture include his namesake Bachman diagrams. Biography Charles Bachman was born in Manhattan, Kansas, in 1924, where his father, Charles Bachman Jr., was the head football coach at Kansas State College. He attended high school in East Lansing, Michigan, where his father served as head football coach at Michigan State College from 1933-1946. In World War II he joined the United States Army and spent March 1944 through February 1946 in the South West Pacific Theater serving in the Anti-Aircraft Artillery Corps in New Guinea, Australia, and the Philippine Islands. There he was first exposed to and used fire control computers for aiming 90& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GE-200 Series
GE 210 advertisement from 1960 The GE-200 series was a family of small mainframe computers of the 1960s, built by General Electric (GE). GE marketing called the line ''Compatibles/200'' (GE-205/215/225/235). The GE-210 of 1960 is not compatible with the rest of the 200 series. 200 series models The main machine in the line was the GE-225 (1961). It used a 20-bit word, of which 13 bits could be used for an address. Along with the basic central processing unit (CPU) the system could also include a floating-point unit (the "Auxiliary Arithmetic Unit"), or a fixed-point decimal option with three six-bit decimal digits per word. It had 11 I/O channel controllers, and GE sold a variety of add-ons including disks, printers and other devices. The machines were built using discrete transistors, with a typical machine including about 10,000 transistors and 20,000 diodes. They used magnetic-core memory, and a standard 8 k-word system held 186,000 magnetic cores. They weighed abou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric Mainframe Computers
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO rank scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navigational Database
A navigational database is a type of database in which records or objects are found primarily by following references from other objects. The term was popularized by the title of Charles Bachman's 1973 Turing Award paper, ''The Programmer as Navigator''. This paper emphasized the fact that the new disk-based database systems allowed the programmer to choose arbitrary navigational routes following relationships from record to record, contrasting this with the constraints of earlier magnetic-tape and punched card systems where data access was strictly sequential. One of the earliest navigational databases was Integrated Data Store (IDS), which was developed by Bachman for General Electric in the 1960s. IDS became the basis for the CODASYL database model in 1969. Although Bachman described the concept of navigation in abstract terms, the idea of navigational access came to be associated strongly with the procedural design of the CODASYL Data Manipulation Language. Writing in 1982, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodrich Corporation
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Benjamin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems. In 1869, Benjamin Goodrich purchased the Hudson River Rubber Company, a small business in Hastings-on-Hudson, New York. The ...

IDMS
The Integrated Database Management System (IDMS) is a network model (CODASYL) database management system for mainframes. It was first developed at B.F. Goodrich and later marketed by Cullinane Database Systems (renamed Cullinet in 1983). Since 1989 the product has been owned by Computer Associates (now CA Technologies), who renamed it Advantage CA-IDMS and later simply to CA IDMS. History The roots of IDMS go back to the pioneering database management system called Integrated Data Store (IDS), developed at General Electric by a team led by Charles Bachman and first released in 1964. In the early 1960s IDS was taken from its original form, by the computer group of the B.F. Goodrich Chemical Division, and re-written in a language called Intermediate System Language (ISL). ISL was designed as a portable system programming language able to produce code for a variety of target machines. Since ISL was actually written in ISL, it was able to be ported to other machine architectures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weyerhaeuser
Weyerhaeuser () is an American timberland company which owns nearly of timberlands in the U.S., and manages an additional of timberlands under long-term licenses in Canada. The company also manufactures wood products. It operates as a real estate investment trust. History In 1904, after years of successful Mississippi River-based lumber and mill operations with Frederick Denkmann and others, Frederick Weyerhäuser moved west to fresh timber areas and founded the Weyerhäuser Timber Company. Fifteen partners and of Washington timberland were involved in the founding, and the land was purchased from James J. Hill of the Great Northern Railway. In 1929, the company built what was then the world's largest sawmill in Longview, Washington. Weyerhaeuser's pulp mill in Longview, which began production in 1931, sustained the company financially during the Great Depression. In 1959, the company eliminated the word "Timber" from its name to better reflect its operations. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association For Computing Machinery
The Association for Computing Machinery (ACM) is a US-based international learned society for computing. It was founded in 1947 and is the world's largest scientific and educational computing society.

Network Model
The network model is a database model conceived as a flexible way of representing objects and their relationships. Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice. The network model was adopted by the CODASYL Data Base Task Group in 1969 and underwent a major update in 1971. It is sometimes known as the CODASYL model for this reason. A number of network database systems became popular on mainframe and minicomputers through the 1970s before being widely replaced by relational databases in the 1980s. Overview While the hierarchical database model structures data as a tree of records, with each record having one parent record and many children, the network model allows each record to have multiple parent and child records, forming a generalized graph structure. This property applies at two levels: the schema is a generalized graph of record types conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turing Award
The ACM A. M. Turing Award is an annual prize given by the Association for Computing Machinery (ACM) for contributions of lasting and major technical importance to computer science. It is generally recognized as the highest distinction in computer science and is colloquially known as or often referred to as the " Nobel Prize of Computing". The award is named after Alan Turing, who was a British mathematician and reader in mathematics at the University of Manchester.
