SYSTEM AND METHOD FOR GENERATING DATABASE SEARCH COMMANDS Abstract A data base manager program (100-307) and rela- tional data are stored in memory (352). The program sequentially generates a plurality of prompt screens on a display (353). Operator responses thereto, input at keyboard (351), define a query statement which, when executed by a processor (350) retrieves a correl- ative data subset from the memory. The query is comprised of clauses (180-185). A plurality of sequential prompt screen-responses specify at least one of the clauses. Available valid response choices and/or response instructions dis- played in a screen automatically appear and are varied as a function of response to the prior screen. In one embodiment, the left side (280), comparison operator (281), and right side (282) of a row condition clause are each specified by at least one prompt screen-response. When the left side or right side is complex including a summary function or expression, a sequential plurality of prompt screen-responses specifies the respective left or right side. The system and method enable a database user to specify complex query statements without knowledge of the syntax and semantics of the query language.
