Abstract

PURPOSE:To execute the processing by only indicating a name of a desired retrieval processing definer in accordance with an instruction, by providing a retrieval processing definer for defining a condition for executing a retrieval processing, as well as definers of a skimmer and a subskimmer, and registering them in a library. CONSTITUTION:In order to generate a retrieval processing definer 11 in a library 10, a name of the retrieval processing definer, a record type to be used, a set type in case of a retrieval processing, an attribute data in case when said type is used, an end condition of the retrieval processing, etc. are inputted through a card reader 7. Corresponding to this input, a data processing equipment 8 executes buffering for editing as to a data of hierarchy regarding a record type having a hierarchical structure, its attribute, its end condition, etc., to an editing buffer 12, prints out to a printer 9, checks them up, and after that, registers them as one retrieval processing definer ABCD11 in the library 10. In case when a retrieval processing is executed, the definer 11 is read by a control buffer part on a main memory device, and a record type is accessed in accordance with hierarchy based on the contents of the definer 11.
