Peter Schnell (computer Scientist)
Peter M. Schnell (born 10 June 1938 in Berlin) is a German computer scientist, founder of Software AG and long-time chairman of the ''Vorstand'', executive board. Life He grew up in Alsbach-Hähnlein near Darmstadt. Schnell was impressed by the IBM 650, the first commercial mainframe computer that Alwin Walther had procured for Technische Universität Darmstadt (TU Darmstadt). He then studied physics and mathematics at TU Darmstadt. In 1965 he graduated with a diplom in mathematics under Walther. Already as a student he gave courses in programming languages and worked as a freelance programmer for Euratom and at the German Computer Center in Darmstadt. He was one of the best Go players in Europe. Software AG In 1969, together with five other colleagues from the Institute for Applied Information Processing (AIV), Schnell founded Software AG in Darmstadt out of a garage with a starting capital of 6.000 German Mark and several patents. Among the colleagues was Peter Pagé, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Relational Algebra
In database theory, relational algebra is a theory that uses algebraic structures for modeling data and defining queries on it with well founded semantics (computer science), semantics. The theory was introduced by Edgar F. Codd. The main application of relational algebra is to provide a theoretical foundation for relational databases, particularly query languages for such databases, chief among which is SQL. Relational databases store tabular data represented as relation (database), relations. Queries over relational databases often likewise return tabular data represented as relations. The main purpose of relational algebra is to define Operator (mathematics), operators that transform one or more input relations to an output relation. Given that these operators accept relations as input and produce relations as output, they can be combined and used to express complex queries that transform multiple input relations (whose data are stored in the database) into a single output rela ...

Rudolf Steiner
Rudolf Joseph Lorenz Steiner (; 27 or 25 February 1861 – 30 March 1925) was an Austrian occultist, social reformer, architect, esotericist, and claimed clairvoyant. Steiner gained initial recognition at the end of the nineteenth century as a literary critic and published works including '' The Philosophy of Freedom''. At the beginning of the twentieth century he founded an esoteric spiritual movement, anthroposophy, with roots in German idealist philosophy and theosophy. His teachings are influenced by Christian Gnosticism or neognosticism.Sources for 'Christian Gnosticism': Many of his ideas are pseudoscientific. He was also prone to pseudohistory.Sources for 'pseudohistory': In the first, more philosophically oriented phase of this movement, Steiner attempted to find a synthesis between science and spirituality. His philosophical work of these years, which he termed " spiritual science", sought to apply what he saw as the clarity of thinking characteristic of West ...

Bonn
Bonn () is a federal city in the German state of North Rhine-Westphalia, located on the banks of the Rhine.

University Of Witten-Herdecke
Witten/Herdecke University is a private, state-recognized, nonprofit university in Witten, North Rhine-Westphalia, Germany. It was the first German private institution of higher education to receive accreditation as a "Universität", a status recognizing the university's academic quality equivalent to state-run universities and granting the right to award bachelor's and master's degrees, doctorates, and the German Habilitation. Its foundation and history has often been marked by controversial debates and significant difficulties to establish the new university in the German educational system. In 1995, ''Times Higher Education'' noted that the university was considered by some "an idealistic model for the future of German higher education and yothers ... a carbuncle on the country's fiercely state-dominated university landscape".

Anthroposophist
Anthroposophy is a spiritual new religious movementSources for 'new religious movement': which was founded in the early 20th century by the esotericist Rudolf Steiner that postulates the existence of an objective, intellectually comprehensible spiritual world, accessible to human experience. Followers of anthroposophy aim to engage in spiritual discovery through a mode of thought independent of sensory experience. Though proponents claim to present their ideas in a manner that is verifiable by rational discourse and say that they seek precision and clarity comparable to that obtained by scientists investigating the physical world, many of these ideas have been termed pseudoscientific by experts in epistemology and debunkers of pseudoscience.Sources for 'pseudoscience': Anthroposophy has its roots in German idealism, Western and Eastern esoteric ideas, various religious traditions, and modern Theosophy. Steiner chose the term ''anthroposophy'' (from Greek ἄνθρωπος , 'h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the Programmed Data Processor, PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space.
