The Research Of Experimental Database System Based On VC And SQL Server

Data acquisition and processing is an important branch of computer applications, mainly researched data acquisition, storage, processing and control. The latest development of computer networking technology promotes the rapid updating of data acquisition and processing technologies. When the main application areas of computer gradually shift from science calculations to the business data processing, database technology came into being..In recent years, CAI experiments is more and more important in modern teaching equipment. Using computer's fast, powerful data management functions and network functions, computers and laboratory devices can be made up of a computer network, VC++ is a visualization programming environment, support rich function and network, and provides powerful MFC to simplify the use of Windows applications, support Multithread program.As a high-performance relational database system, SQL Server2000 can respond quickly to requests for information efficient. The issue is a system software at the basis of the existing electrical experiments using the visualization of VC++ and SQL Server 2000 database , which has good interactive environment and can collect, process rapidly experimental data.Specifically, the major research content: the agreement of communications, data synchronization, preservation in the high-speed communications, the storage structures of database.and other functions.Development of system management: control procedures, communications procedures. Using the ODBC interface of VC, we manage database through standard function and SQL,Serial communications has some features, such as simple structure, programming convenient, low-cost,. In many systems to achieve serial communications, it implemented a number of procedures and make full use of CPU time work increased operational efficiency, making Serial communications applications more flexible, more widely.In VC++ environment, we can maintain the target systems simultaneously through the use of established events to, using two monitoring function to enhance the efficiency and reliability of data reception systems and other measures to achieve more serial communications. A multi-systems approach to Serial communications in high-speed communications can ensure conditions that accurated data and completely data synchronization conservation, and other functions.
