Access Query Language
Access, the successor to ENGLISH, is an English-like query language used in the Pick operating system The Pick Operating System (Pick System or Pick) is a demand-paged, multi-user, virtual memory, time-sharing computer operating system based around a MultiValue database. Pick is used primarily for business data processing. It is named after one of .... The original name ENGLISH is something of a misnomer, as PICK's flexible dictionary structure meant that file and attribute names could be given aliases in any natural language. For instance the command SORT could be given the alias TRIEZ, the file CUSTOMER the alias CLIENT, the attribute BALANCE the alias BILAN and the particle BY the alias PAR. This would allow the database to be interrogated using the French-language command string "TRIEZ CLIENT PAR BILAN", resulting in a list of customers by balance. Etomology The ''Access'' query (or enquiry) language is known by different names on different implementations of Pick: with ''E ...

ENGLISH (programming Language)
Microdata Corporation was an American minicomputer company which created the Reality product line featuring the Pick operating system. In its history, Microdata * was taken over by its international distributor CMC Leasings (December 1969), * which in turn was taken over in 1983 by McDonnell Douglas Corporation (March 1983), * that division was spun off as McDonnell Douglas Information Systems (1993) * which became part of Northgate Information Solutions (April 2000). * which was acquired by NEC in 2018 and rebranded to NEC Software Solutions UK in 2021. The company was initially formed as a hardware company. Independently, TRW Inc., TRW, in fulfillment of a mid-1960s US government contract to build software to track inventory, developed a database system named Generalized Information Retrieval Language System (GIRLS). As a public domain item, a developer named Richard Pick was free to use it as the basis of a subsequent work, which eventually became the Pick operating system. ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Query Language
Query languages, data query languages or database query languages (DQL) are computer languages used to make queries in databases and information systems. A well known example is the Structured Query Language (SQL). Types Broadly, query languages can be classified according to whether they are database query languages or information retrieval query languages. The difference is that a database query language attempts to give factual answers to factual questions, while an information retrieval query language attempts to find documents containing information that is relevant to an area of inquiry. Other types of query languages include: * Full-text. The simplest query language is treating all terms as bag of words that are to be matched with the postings in the inverted index and where subsequently ranking models are applied to retrieve the most relevant documents. Only tokens are defined in the CFG. Web search engines often use this approach. * Boolean. A query language that also s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pick Operating System
The Pick Operating System (Pick System or Pick) is a demand-paged, multi-user, virtual memory, time-sharing computer operating system based around a MultiValue database. Pick is used primarily for business data processing. It is named after one of its developers, Richard A. (Dick) Pick. The term "Pick system" has also come to be used as the general name of all operating environments which employ this multivalued database and have some implementation of Pick/BASIC and ENGLISH/Access queries. Although Pick started on a variety of minicomputers, the system and its various implementations eventually spread to a large assortment of microcomputers, personal computers, and mainframe computers. Overview The Pick Operating System consists of a database, dictionary, query language, procedural language (PROC), peripheral management, multi-user management, and a compiled BASIC Programming language. The database is a ' hash-file' data management system. A hash-file system is a collection of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
