Code Generation for Graphic User Interfaces of Database Query Based on Information Constraint
Jiancheng Wan · Jisuanji gongcheng · 2002
After the discussion of problems presented in the design of database query and its graphic user interfaces(GUI), this paper proposes a formal method for the code generation of database query and its GUI implementation. The method is based on the information description of table structures, information sources and other constraints of database tables. The logic of disjoint-well-formed-formula is adopted in the generation of query conditions, and standard visual objects are used in the generation of GUI. This method has been implemented and applied in practical applications. ;;;;
