Formatted File System
The Formatted File System (FFS) is the name of a series of Database Management System, Database Management Systems (DBMS) developed for military use and designed to run on IBM mainframe computers. The period from 1964 to 1968 saw the transition from isolated DBMS development efforts to the development of DBMS families. The Formatted File System is one such family. Others included General Electric's Integrated Data Store, IDS family, and the MARK-IV (Software), Mark IV series developed by Informatics General, Informatics Inc. (later acquired by Sterling Software). These families were developed across organizations and branches of government, spreading and evolving with their primary developers. Beginning around 1968, industry DBMS development became increasingly proprietary.

Database Management System
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an applicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 IDMS ...

MARK-IV (Software)
MARK IV is a fourth-generation programming language that was created by Informatics, Inc. in the 1960s. Informatics took advantage of IBM's decision to unbundle their software; MARK IV was the first "software product to have cumulative sales of $10 million". MARK IV was developed for IBM Systems (360 and 370) and for the RCA Spectra 70. Its main benefit was allowing faster application development on the order of 6 to 10 times faster than doing a system using a 3GL, such as COBOL. MARK IV, being an early 4GL, allowed user development of systems related to business. In a 1971 ad by Informatics, there are several quotes from customers, such as: :We conservatively estimate that the benefits derived from the MARK IV System have completely returned the cost of our investment in a period of less than 3 months. :MARK IV runs ... handle Accounts Receivable, Inventory, Sales Analyses, etc. on about 26 different factories. MARK IV went to Sterling Software in 1985 as part of that compan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informatics General
Informatics General Corporation, earlier Informatics, Inc., was an American computer software company in existence from 1962 through 1985 and based in Los Angeles, California. It made a variety of software products, and was especially known for its Mark IV file management and report generation product for IBM mainframes, which became the best-selling corporate packaged software product of its time. It also ran computer service bureaus and sold turnkey systems to specific industries. By the mid-1980s Informatics had revenues of near $200 million and over 2,500 employees. Computer historian Martin Campbell-Kelly, in his 2003 volume ''From Airline Reservations to Sonic the Hedgehog: A History of the Software Industry'', considers Informatics to be an exemplar of the independent, middle-sized software development firms of its era, and the Computer History Museum as well as the Charles Babbage Institute at the University of Minnesota have conducted a number of oral histories of the c ...

Sterling Software
Sterling Software was an American software company founded in Dallas, Texas in 1981 by Sterling Williams and brothers Sam and Charles Wyly. The company was acquired by Computer Associates International in 2000 in a stock-for-stock transaction worth $3.3 billion. Computer Associates sold Sterling Software's Federal Systems Group to Northrop Grumman in 2000. It was known for its aggressive acquisitions, most notably the hostile take-over of Informatics General Corporation in 1985. Informatics was one of the first established software and services companies. It developed the MARK-IV Fourth-generation programming language in the 1960s. MARK-IV became the first software package exceeding $1 million in revenue, after IBM was forced in 1969 to unbundle software from their hardware. Helped by financing and counseled by Werner Frank, one of Informatics' founders who had left this company a year before, Sterling Software started the hostile take over by offering to shareholders an ...

David Taylor Model Basin
The David Taylor Model Basin (DTMB) is one of the largest ship model basins—test facilities for the development of ship design—in the world. DTMB is a field activity of the Carderock Division of the Naval Surface Warfare Center. History In 1896, David Watson Taylor designed and supervised construction of the Washington Navy Yard's Experimental Model Basin which was at that time the best facility in the world. That facility was a significant design testing capability before, during, and after World War I. Inadequacies in that facility led the navy to look for a new model capability. The new navy modeling facility – named for David Taylor – was built in 1939 in today's community of Carderock just west of Bethesda, Maryland in Montgomery County. The Carderock facility contains multiple test basins (towing tanks for models) designed for a variety of testing capabilities. DTMB has strongly influenced naval architecture for 70 years.

Strategic Air Command
Strategic Air Command (SAC) was both a United States Department of Defense Specified Command and a United States Air Force (USAF) Major Command responsible for command and control of the strategic bomber and intercontinental ballistic missile components of the United States military's strategic nuclear forces from 1946 to 1992. SAC was also responsible for the operation of strategic reconnaissance aircraft and airborne command post aircraft as well as most of the USAF's aerial refueling fleet, including aircraft from the Air Force Reserve (AFRES) and Air National Guard (ANG). SAC primarily consisted of the Second Air Force (2AF), Eighth Air Force (8AF) and the Fifteenth Air Force (15AF), while SAC headquarters (HQ SAC) included Directorates for Operations & Plans, Intelligence, Command & Control, Maintenance, Training, Communications, and Personnel. At a lower echelon, SAC headquarters divisions included Aircraft Engineering, Missile Concept, and Strategic Communicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
