Nomad Software
NOMAD is a relational database and fourth-generation language (4GL), originally developed in the 1970s by time-sharing vendor National CSS. While it is still in use today, its widest use was in the 1970s and 1980s. NOMAD supports both the relational and hierarchical database models. NOMAD provides both interactive and batch environments for data management and application development, including commands for database definition, data manipulation, and reporting. All components are accessible by and integrated through a database-oriented programming language. Unlike many tools for managing mainframe data, which are geared to the needs of professional programmers in MIS departments, NOMAD is particularly designed for (and sold to) application end-users in large corporations. End-users employ Nomad in batch production cycles and in Web-enabled applications, as well as for reporting and distribution via the web or PC desktop. Capabilities NOMAD is distinguished by five characteristi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relational Database
A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using the SQL (Structured Query Language) for querying and maintaining the database. History The term "relational database" was first defined by E. F. Codd at IBM in 1970. Codd introduced the term in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by "relational". One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a minimum: # Present the data to the user as relati ...

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 ...

Christopher J
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), "Christ" or "Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as "Chris", "Topher", and sometimes " Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. The name is most common in England and not so common in Wales, Scotland, or Ireland. People with the given name Antiquity and Middle Ages * Saint Christopher (died 251), saint venerated by Catholics and Orthodox Christians * Christopher (Domestic of the Schools) (fl. 870s), Byzantine general * Christopher Lekapenos (died 931) ...

IBM System R
IBM System R is a database system built as a research project at IBM's San Jose Research Laboratory beginning in 1974. System R was a seminal project: it was the first implementation of SQL, which has since become the standard relational data query language. It was also the first system to demonstrate that a relational database management system could provide good transaction processing performance. Design decisions in System R, as well as some fundamental algorithm choices (such as the dynamic programming algorithm used in query optimization), influenced many later relational systems. System R's first customer was Pratt & Whitney in 1977..

Assembly Language
In computer programming, assembly language (or assembler language, or symbolic machine code), often referred to simply as Assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an ''assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book ''The Preparation of Programs for an Electronic Digital Com ...

VP/CSS
VP/CSS was a time-sharing operating system developed by National CSS. It began life in 1968 as a copy of IBM's CP/CMS, which at the time was distributed to IBM customers at no charge, in source code form, without support, as part of the IBM Type-III Library. Through extensive in-house development, in what today would be termed a software fork, National CSS took VP/CSS in a different direction from CP/CMS. Although the two systems would eventually share many capabilities, their technical implementations diverged in substantive ways. VP/CSS ran on IBM and IBM plug compatible hardware owned by NCSS (and by a few customers with site licenses, including Bank of America and Standard Oil of California). After an initial period running on the IBM System/360-67 platform used by CP/CMS, VP/CSS was ported to the System/370 series, made possible when IBM added virtual memory capabilities to the S/370 series in 1972. VP/CSS was notable for supporting very large numbers of interactive users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
