Design of Economic Model Base in City Industry Programming
Zhao Yu-peng · Journal of Guangxi Teachers Education University · 2007
Aiming at the complexity of economic model in city industry programming,five principles about how to design model base are advanced to decrease redundancy in model base,component model and executable model are distinguished,component model is expressed as executable file and executable model is expressed as data sequence in data table.By digitizing the algebraic expression and executable model,the capacity of knowledge expressed in relation data base is enhanced,and the readability of model is increased.Based on these,the model base management system is designed by mixing file system and relation data base system,redundancy is decreased and uniformity is increasing in model base.
