The Design of Energy Database for a Sheet Manufacturer
Abstract: The role of information in the social and economic development more and more importance for the people. The level of the development and utilization of information resources is one important indicator of measuring a country's comprehensive national strength. Computer as a tool for information processing, to adapt to the rapid increase of data processing requirements to meet the requirements of various information systems for data management,file system based on the development of the underlying database system database transaction processing large amounts of data management needs. The sheet plant according to the meter reading data， created in Visual Fox pro 6.0 database file,while using VFP 6.0 man-machine interface to operate the database，so that the the energy database system has system maintenance,energy data to add,modify,report output and planned energy data input,modify and query performance value and the planned value,performance,value and the planned value comparison.
