The Research On Materials Management System Visualized Of Digital Enterprise

With Geographic Information System(GIS) being widely used in different area, it's decision-supporting is becoming more and more important. And the technique of developing application of GIS has become more variety with the development of the software technique. Component technique is the new tide of software development and it is more advanced in developing application of GIS than traditional ways.It's blank that applying GIS into enterprise and making enterprise information visualized in domestic and overseas. So studying enterprise fundamental geography information system has a very important signification. But this system project is very complicated, this dissertation about to study materials management of enterprise and the shortest path inside enterprise.Materials management system visualized of digital enterprise Geography Information System is a kind of special information technique to exert computer's software, hardware and communications technique, and to realize enterprise special data and non-special data input, store, inquire, searches, deal with, analyze, display, updating, enterprise-management, assistant decision-making, forecast, enterprise construct. It unite geographic position and correlation property very good, according to consumer's real demand, it can offer consumer a kind of precision and reality's information, to satisfy corporation management. And in virtue of its special space analysis and visual expression can deal with lots of assistant decision-making.But up to now, most of materials management systems begin with nothing, and in database construct aspect, because different departments adopt vary file format, it makes lots of data repeat construct and data communion is very difficult. Accordingly, construct a public enterprise fundamental geography information system (include database coding) can reduce enterprise data repeat construct, saving money, ac,accelerate enterprise information change. So studying enterprise fundamental geography information system has a very important signification.The dissertation introduces development progress of this system in the aspect of software project, and it includes collectivity design, database design, encoding and test, etc. Take advantage of Visual Basic 6.0, ESRI's MapObjects and SQL Server 2000 construct enterprise fundamental geography information system. Also this system obtained provides normal GIS functions, Such as map display, zooming in, zooming out, panning, and addition of special graph. Furthermore, other functions, like map-data input, delete and edit, place name statistic map or map-data, will be in the charge of this system.By making use of special database technology based on the mode of Client/Server relationship, the system adopts visual program technology of component model and integrates module models of this system's function, which imposed on the system is to achieve swift exploitation and compound use.
