The Design And Realization Of A Teaching Management Information System On Multi-tier Distributed Structure

With the development of the application and the enlargement of systematic scale in computer domain, on one hand the complication of software also is increasing continuously; on the other hand the functions of systematic structure of software are more and more significant in the procedure for designing and exploiting for software. Because of it virtues such as flexibility, configurability, reliability and embodying the thought of integrated software etc., Multi-tier distributed structure mould is putting in use popularly.In this article the development of the management information system on the Multi-tier Distributed structure is described by means of a specific example in detail. Above of all, in the beginning of the article, we present the development and the technical characteristics of the Multi-tier Distributed structure systematically. Subsequently, the article puts the emphasis on the core of the managementinformation system.....the database technology, and analyses the maincharacteristics of database management system in combination with the MS SQL Server 2000. Finally, we take the teaching management system as an instance to discuss the whole exploiting process, in which there are three stages, that is, the system analyses, the system design and the system implement, and especially the article emphasizes on the adjustment of the system capability.A new development methodology is used, that is, in the course of the system analysis and design, there is the combination of life circle approach and prototyping approach, but the object-oriented program design methodologies in the procedure of the system implement. Using this method to exploit system, the users can take part in the development process of the system utmost, and the system can be in corps with the needs of users preferably. In order to strengthen the security and stability of the system, the technology of data interim store is applied. When the database server or application server is out of control, the users can store the updated data into the client computers; after the database server or application server can work, the users load the data and update into the database.
