The Mine Cost Management System Based On Distributed Database

Along with the rapid development of information technology and networking, especially internet, the structure of information systems has tent to become distributed. Data sharing and retrieving in large-span or global area; Meanwhile, the enterprises have being faced larger opportunities and challeges after China joined into WTO. For rapided adapting to new economy and new environments, according with international manage mode, shorting the study period of new products, falling the costs, improving work efficiencies, and increasing the whole benefits and key rivalrousness, many enterprises have based informations.Enterprises have always faced the stress from higher costs in informations. Each manager will face to the cost control management, when they think work and actions. It is important if we can reasonable control costs, we must affirmative adopt manage costs , for more increasing competition of the glob. The cost computing and management is importance and difficulty, while it is the key of ERP. How do we build one scientific cost management and analyzing systems? It is important in our paper. To enterprise, they are concerned about cost management for all time. Not it is business rule, but it is a kind of bylaw. Computing and management cost is not only belong to financial people, but also it is belong to every body. They are personal, enquipment, fixed assets, storehouse, workshop, goods, and so on. We have designed one cost management system with coal wine. We try our best to give a hand in improving cost management.For coal mine enterprise adopted DBMS with PC. There is much malpractice. People can not share information each other, and can not logical use effective resources, extending is not easy. So we adopt distributed Database to design cost management system of coal mine. Database is key in the whole software. What's more distributed Database is more complex than focus Database, we try our best to clarity visit Database through the whole object mode. So global users need not think of the composes of system, we also study query technology.Lastly, we introduce the design thinks and functions of coal mine cost management system, we can claritly visit this system, and view the future. Meanwhile we adopt DDBMS to avoid the different structure. System extending is so easy, and it is realized query-optimize.
