Pick operating system
The Pick Operating System, also known as the Pick System or simply 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, 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.
The Pick Operating System is an integrated computing platform with a database, query and procedural operation languages, peripheral and multi-user management, and BASIC programming capabilities. Its database utilizes a hash-file system, enabling efficient data storage and retrieval by organizing data into dynamic associative arrays managed by associative files.
Data within the Pick system is organized into a hierarchical structure of accounts, dictionaries, files, and sub-files based on a hash-table model with linear probing. This structure comprises variable-length records, fields, and sub-fields, with unique naming conventions that reflect its multivalued database characteristics. Records are identified by unique keys that facilitate direct access to their storage locations.
Initially constrained by the era's technological limitations, the Pick system's capacity has expanded over time, removing earlier record-size limits and introducing dynamic file allocation and B-tree indexing to enhance data management capabilities.
The Pick database operates without explicit data types, treating all data as character strings, which places the onus of data integrity on the applications developed for the system. This flexibility allows Pick to store data in non-first-normal-form, avoiding the need for join operations by containing all related data within single records. This approach can optimize storage and retrieval efficiency for specific kinds of datasets.
Pick was originally implemented as the Generalized Information Retrieval Language System (GIRLS) on an IBM System/360 in 1965 by Don Nelson and Dick Pick at TRW, whose government contract for the Cheyenne Helicopter project required developing a database. It was supposed to be used by the U.S. Army to control the inventory of Cheyenne helicopter parts.
Pick was subsequently commercially released in 1973 by Microdata Corporation (and its British distributor CMC) as the Reality Operating System now supplied by Northgate Information Solutions. McDonnell Douglas bought Microdata in 1981.
