Technology Management Information System Based On Object-oriented Design And Implementation

The research objective is to design and implement a technology based on object-oriented technology of coal enterprise management information system, large-scale coal enterprises to improve the management of the level of technological innovation.First of papers based on object-oriented (MIS) technology in the development of the situation at home and abroad, and MIS related technologies such as object-oriented technology, B / S + C / S three-tier architecture technology, distributed database technology and the realization of conduct were discussed.The use of object-oriented technology Yankuang Group Technology Center, as well as the various units under the jurisdiction of the management of the affairs of science and technology needs analysis, design of the overall technical program. Design and Technology in the Management Information System will be given when the B/S and C/S combination of centralized control with self-government a combination of new architecture to enhance system scalability, reliability and capacity of load balancing.At the same time, the paper design Yankuang Group Technology Center database system, analysis of the traditional paradigm of the three database systems design idea, a new dynamic database of user-level design, enabling the system to dynamically establish the key mapping table data structure and corresponding data entry interface and query interface, adapted to Yankuang Group Technology Management data sheet flexibility, and fast update. Finally, the paper describes the system, client development and the achievement of the specific methods and the various functional modules of the detailed design, and examined the security of distributed systems and database backup and recovery and so on.
