Data base management system  (DATA base management system)

A user (225-5) can process his problem by writing a program (225-8) in a general programming language 1 such as Fortran, Cobol, Basic or Algol, or a specific language, designed to use the processing programs (226-9) stored in the central memory (226-2) of the computer such as a data base management system 2 used to create and maintain a data bank 2, a survey processing program 3 or a statistical package 4. The devices which are used to enter and receive information from the computer can differ according to the mode of processing. In batch processing 7, the normal input and output units are the card reader 5 and the line printer 6. A console 8 is the normal input and output unit for processing in a timesharing mode 9. In either instance the entry units may be spatially separated from the computer and processing under these conditions is accomplished by remote terminal 10.
