Applications of Recursive-descent Parsing in Combinatorial Query
Zhou Ming · Microcomputer Development · 2004
Combinatorial query is the point in the development of management information system.This paper discusses the designs and implementation of a combinatorial query mechanism,a brief introduction to recursive-descent parse is given in this paper.The basic functions of combinatorial query mechanism are discussed.Then,proposes the description and analyzes method of the combina torial query conditions used by recursive-descent parse.Finally,the detailed implementations based on MVC pattern are presented.This method can meet the comprehensive requests of several aspects,such as the condition randomize,output diversity and interface friendship,etc.
