The Study And Realization On Insect Classification Query Identification System Based On Web

With the rapid development of computer and network technology,application field of computer has been expanded and it is applied in every walk of life,and it is altering people's life and working step and step.By database technology and expert system thought,a insect classification query expert system based on Web technology has been designed in this system.This insect ciassification query system is a database system for Yunnan insect classification and identification,and it can carry out entomic assistant identification in the rank field of item,section,category and sort.Two large databases of insect classification and insect identification repository have been build with SQL 2000 relation database in this system.And it has been disport four subsystems of insect classification,insect query,insect identification and background database management, then the function of rank scan,query and identification have been came true,and man-machine alternation of entomologists and insect enthusiasts has been convened in this system.And a humanness interface of operation background database is offered for managers.Asp language is used to realize to program in this system,and using IE browser carry out man-machine alternation.The advantage of expert system based on Web is plentifully embodied and real time on-line search functions are conveniently realized by user.There are several characteristics in insect classification query expert system based on Web.For example,using dynamic build tree come true vision subsystem,it can realize insect information browser for user as same as operating explorer interface in windows,and it also makes administrator dynamically add to crunodes information of every tank's item,section,category and sort.Search subsystem adopt mode of many entry search to improve search's alternative area and speed,so it has more agilities and feasible.Insect identification subsystem use two fork tree of data fabric theory to carry out build of insect repository,and it predigest difficult of building repository,so identification function is prone to realize and some problem of expert system have been overcame such as more workload of prophase,long of design period,it is an innovate point in this system.Every main information table functions in insect sort database and identification repository are realized by background database management subsystem such as insert,delete,amend and so on,it convince manager's operation in this system.It is nicety and effective for insect phyletic identification in this system,the design method of adopting in this system also has definite reference meaning to design other analogous system.
