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] |
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 ...

9PAC
9PAC is a common abbreviation for 709 PACkage. It was a report generator developed in 1959 for the IBM 709 and used on its successor, the IBM 7090. It was developed by SHARE, an early IBM users' group, and based on the File Maintenance and Report Generator System developed by General Electric for the IBM 702, led by Harry Tellier. Charles Bachman worked on its design in 1957, and although his company's order for the 709 was cancelled, he later included some of its general concepts into the more generalized idea of navigational databases. Engineers at companies such as Union Carbide, Northwest Power Company, Philips Petroleum, Dow Chemical, and Chrysler cooperated on the project. Further reading * Jean E. Sammet Jean E.

Manhattan, Kansas
Manhattan is a city and county seat of Riley County, Kansas, United States, although the city extends into Pottawatomie County. It is located in northeastern Kansas at the junction of the Kansas River and Big Blue River. As of the 2020 census, the population of the city was 54,100. The city was founded by settlers from the New England Emigrant Aid Company as a Free-State town in the 1850s, during the Bleeding Kansas era. Nicknamed "The Little Apple" as a play on New York City's "Big Apple", Manhattan is the home of Kansas State University and has a distinct college town atmosphere. History Native American settlement Before settlement by European-Americans in the 1850s, the land around Manhattan was home to Native American tribes. From 1780 to 1830, it was home to the Kaw people, also known as the Kansa. The Kaw settlement was called Blue Earth Village (Manyinkatuhuudje), named after the river which the tribe had named the Great Blue Earth River, today known as t ...

IBM 709
The IBM 709 was a computer system, initially announced by IBM in January 1957 and first installed during August 1958. The 709 was an improved version of its predecessor, the IBM 704, and was the third of the IBM 700/7000 series of scientific computers. The improvements included overlapped input/output, indirect addressing, and three "convert" instructions which provided support for decimal arithmetic, leading zero suppression, and several other operations. The 709 had 32,768 words of 36-bit magnetic core memory and could execute 42,000 add or subtract instructions per second. It could multiply two 36-bit integers at a rate of 5000 per second. An optional hardware emulator executed old IBM 704 programs on the IBM 709. This was the first commercially available emulator. Registers and most 704 instructions were emulated in 709 hardware. Complex 704 instructions such as floating point trap and input-output routines were emulated in 709 software. The FORTRAN Assembly Program was firs ...

Report Generator
A report generator is a computer program whose purpose is to take data from a source such as a database, XML stream or a spreadsheet, and use it to produce a document in a format which satisfies a particular human readership. Report generation functionality is almost always present in database systems, where the source of the data is the database itself. It can also be argued that report generation is part of the purpose of a spreadsheet. Standalone report generators may work with multiple data sources and export reports to different document formats. An early report writer was part of the Nomad software. Information systems theory specifies that information delivered to a target human reader must be Timely, Accurate and Relevant. Report generation software targets the final requirement by making sure that the information delivered is presented in the way most readily understood by the target reader.

SHARE (computing)
SHARE Inc. is a volunteer-run user group for IBM mainframe computers that was founded in 1955 by Los Angeles-area users of the IBM 701 computer system. It evolved into a forum for exchanging technical information about programming languages, operating systems, database systems, and user experiences for enterprise users of small, medium, and large-scale IBM computers such as IBM S/360, IBM S/370, zSeries, pSeries, and xSeries. Despite the capitalization of all letters in the name, the official website says "SHARE is not an acronym; it's what we do." Overview A major resource of SHARE from the beginning was the SHARE library. Originally, IBM distributed what software it provided in source form and systems programmers commonly made small local additions or modifications and exchanged them with other users. The SHARE library and the process of distributed development it fostered was one of the major origins of open source software. In 1959 SHARE released the SHARE Operating Syst ...

Midland, Michigan
Midland is a city in and the county seat of Midland County, Michigan. The city's population was 42,547 as of the 2020 census. It is the principal city of the Midland Micropolitan Statistical Area, part of the larger Saginaw-Midland-Bay City Combined Statistical Area. History By the late 1820s, Midland was established as a fur trading post of the American Fur Company supervised by the post at Saginaw. Here agents purchased furs from Ojibwe trappers. The Campau family of Detroit operated an independent trading post at this location in the late 1820s. Dow Chemical Company was founded in Midland in 1897, and its world headquarters are still located there. Through the influence of a Dow Chemical plant opening in Handa, Aichi, Japan, Midland and Handa have become sister cities. Dow Corning was also headquartered in Midland. In 1969, the city unilaterally defined a Midland Urban Growth Area (MUGA), a two-mile territory around the city limits, in an attempt to control urban sprawl. A ...

Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms usually emerge slowly, and as the disease worsens, non-motor symptoms become more common. The most obvious early symptoms are tremor, rigidity, slowness of movement, and difficulty with walking. Cognitive and behavioral problems may also occur with depression, anxiety, and apathy occurring in many people with PD. Parkinson's disease dementia becomes common in the advanced stages of the disease. Those with Parkinson's can also have problems with their sleep and sensory systems. The motor symptoms of the disease result from the death of cells in the substantia nigra, a region of the midbrain, leading to a dopamine deficit. The cause of this cell death is poorly understood, but involves the build-up of misfolded proteins into Lewy bodies in the neurons. Collectively, the main motor symptoms are also known as ...

Tau Beta Pi
The Tau Beta Pi Association (commonly Tau Beta Pi, , or TBP) is the oldest engineering honor society and the second oldest collegiate honor society in the United States. It honors engineering students in American universities who have shown a history of academic achievement as well as a commitment to personal and professional integrity. Specifically, the association was founded "to mark in a fitting manner those who have conferred honor upon their Alma Mater by distinguished scholarship and exemplary character as students in engineering, or by their attainments as alumni in the field of engineering, and to foster a spirit of liberal culture in engineering colleges". History When academic honor society Phi Beta Kappa sought to restrict its membership to students of the liberal arts in the late 19th century, Edward H. Williams Jr., a member of Phi Beta Kappa and head of the mining department at Lehigh University, formulated the idea of an honor society for those studying technic ...

Mechanical Engineering
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
