The Equipment System Design Based On Heterogeneous Database In Colleges

With the development of information technology, management information system has been widespread application, and in the practical application and achieved good results in the face of the practice of equipment management, management information systems not only improve the efficiency of equipment management, while making Equipment in a reasonable allocation of the sector. But most universities are based Institute for device management unit, the mobile device is limited to University internal, did not form in the sharing of resources within the school's equipment management system. Thus making the school there in the use of equipment procurement that repeat purchases, not only wasting a lot of manpower and material resources, but also did not play device application. With the expansion of the school through the current equipment management system has been completely unable to meet the requirements of development, and in practice has shown a lot of management problems. In addition,various departments of the database are based on the Court's practice to develop, so the data structures that exist in significant heterogeneity. Makes the coordination of data communication between the various databases has become difficult to achieve integrated management of equipment.This article is based on the practice of this situation, the use of heterogeneous databases distributed database processing equipment for the school management process has been re-thinking, and combined with my practical experience, design and development of a consistent application of school-based heterogeneous The equipment management system database. Through the implementation of the system, including not only the original investment of each faculty, while also forming a higher level of coordination in various databases integrated device management platform. Makes the device information between various departments are fully shared. And use the data replication technology, asp.net and c#.snapshot technology to maintain consistency between the various databases. The application of this system not only solves the problem of procurement of equipment duplication, and increased equipment movement between the various departments for improving the efficiency of equipment, coordination of various departments to share and use of equipment has certain significance and Reference value.
