Middle School Chemistry Experiment Management System Analysis And Design

In recent years, foreign secondary school chemistry experiment management system has shifted from paper to manage the transition to network general management, but most of the domestic management of middle school chemical experiment teaching and experiment system using the standalone version management, and only school administrators in a separate action, this does not facilitate experimental administrators, teachers, students. Teaching information is lacking, drugs get more links and actions not standard issue. Research and design of management system for chemical experiment in middle school, designed to utilize networks, software and other technology to experiment teaching, laboratory equipment, chemical substance management, modern management methods of chemical experiment teaching, enhance the utilization of laboratory to address management of laboratories in secondary schools of institutionalization and standardization issues, services and information.Essay major work was completed:1, After the study of related technology, the analysis of the system would be completed, including business needs, and functional needs, and data needs and points functional needs. And the experience management business flow diagram about the management of laboratories,administrators and students. And describe teaching of experimental teaching, experience,chemical equipment and low-cost goods management in illustration.2,On the basis of analysis needs, design the system, including overall design, module design, database design. Systems architecture, functional structure will be given out. Use HIPO to express a design of functional module, and apply E-R to describe the design of database and finally to draw out the entity attribute graph, E-R graph and the database table structure.
