The Implementation Of Lab Management Information System Based On Distributed Multi-tier Structure

The management of equipment and laboratory is an important part ofeducational management informationization. It relates to teachers, students, instruments, equipments, experiment teaching, circumstance, bylaws, and so on. At present, there are two methods of managing laboratory, namely manual and automatic management. Manual management method is to be washed out. Automatic management is based on management information system software. Some LabMIS softwares have some shortcomings such so function is not entire, the technology is old, practicality is not good. So these MIS softwares are difficult to be generalized. In this dissertation, a new LabMIS is researched and designed which is based on the Evaluating Method and Standard for the Basic Curriculum Teaching Laboratory of Colleges and the Standard of Educational Management Informationization.This LabMIS adopts distributed technology. It is made of application tier, operation tier and RDBMS. Used distributed technology, LabMIS is stabler, more expansible, more efficient and managed easily.In this LabMIS, Every user can be endowed different permission. For example, laboratory manager, department director and president hold different right. Mostly of function modules of LabMIS consist of user's permission management, transaction processing, importing data, exporting data, basic information management, experience teaching management, integrated querying and statistic, and so on.The structure of this dissertation is based on the idea of software engineering. This dissertation starts with the analysis of user demand, then designs from collectivity, designs defailedly and implements. For the whole system is designed and implemented by two designer, this dissertation mostly discusses the design and realization of client though it analyses and designs from collectivity in front.In the first chapter, it firstly analyses user demand from system functions andcapability. Then addresses the logic model. Finally, puts forward the distributed multi-tier structure after analysing three architectures used in MIS and pointing its pluses and minuses.In the second chapter, it mostly designs from collectivity, including the design of function, database and application server interface.In the third chapter, it briefly presents several primary technology related to the system, including object oriented technology, distributed technology, COM/COM+ technology, MIDAS technology and multi-threaded technology.In the fourth chapter, it elaborates the implementation of primary function modules in client application. Including the implementation of accessing application server using multi-threaded, the implementation of managing user permission, the implementation of dynamic creation lookup fields of ClientDataSet, the implementation of importing and exporting data, the implementation of processing operation, the implementation of experiment teaching management, the implementation of querying and counting.In the last chapter, it discusses the tactic of improving system efficiency and optimizing system interface.
