TurboIMAGE is one of several names used to refer to a database developed by Hewlett Packard and included with the HP3000 minicomputer. TurboIMAGE was also available on the HP250 minicomputer. Originally released under the name IMAGE/3000 in 1972, it was later known as TurboIMAGE, IMAGE/SQL, and TurboIMAGE/XL. IMAGE is the primary reason that the HP3000 was a success. It is a reliable, simple, fast database for MPE. After about a decade of enhancements it was renamed TurboIMAGE, then TurboIMAGE/XL after the PA-RISC migration. Programs can access and update records using IMAGE intrinsics which was HP's name for the API used to access records. Today it is known as IMAGE/SQL because it includes an SQL (Structured Query Language) frontend and client-server support for PC accessors. == Overview == TurboIMAGE consists of several utilities along with an API (referred to as intrinsics by the HP documentation): * DBSCHEMA - Compile a source schema layout. The source layout describes the tables (known as SETS) and columns (known as FIELDS). * DBUTIL - Creates and performs maintenance functions on the database. * QUERY - Generalized query tool for accessing any TurboIMAGE database. The following is a sample list of the API calls used for application development. These calls are supported by HP's compilers: COBOL, FORTRAN, BASIC, SPL, PASCAL and C. * DBFIND - Locates a record. * DBGET - Retrieves a record. * DBPUT - Adds a record. * DBUPDATE - Updates a record. * DBINFO - Provides information on the structure of the database. * DBOPEN - Opens the database with a specified password to provide access rights to the application. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TurboIMAGE」の詳細全文を読む スポンサード リンク
