Material Management System Design And Implementation

With the reform of the education system today, work has become a fast and efficientsolved the problem, and teaching material management is the management of highereducation in an important task, materials management and work efficiency is reflected inteaching and research management important indicator of the level. With the constantexpansion of education, type and quantity of materials is also a sharp increase in the workloadof large material management, the task of heavy, to the materials management personnel topurchase and bring a lot of difficulties, the high error rate, the book is low on school teachingand scientific research have a greater impact. Must make use of computer tools to accomplishthis modern materials management, materials management staff to work from the liberation ofthe heavy, lower error rate, raised to the book rate, to modernize the management of materialprocurement, systematic and standardized, the management level a higher level, so a set ofteaching materials to buy the business waiting for the system that make it more convenient.Throughout the research situation, an independent division also is a college textbookmanagement body responsible for school teaching and research with the general managementof the book to ensure that school teaching and research with the purchase of books andaccurate timely sent to the hands of students and teachers is school teaching and researchwork to be carried out smoothly, material management techniques and methods of how theschool will directly affect the quality of teaching. Materials management division alsoinvolved in many departments, large amount of information in order to standardize thebusiness processes must operate in coordination with the departments concerned to completehigh-quality materials management.Materials management system through feasibility analysis, requirements analysis anddesign, and gradually a textbook management system development process is displayed. Userneeds can be summarized in four aspects:Staff to manage the various types of materials through the computer, including theclassification numbers, finishing material structure.Collar workers through written materials to receive a computer to query the situationto determine their own collection and dissemination of teaching materials, preparematerials for accurate release. Staff receive the book can do fully grasp the situation, timely book for each unit ofthe current leading status and history of the book led record books.Receiving and distribution of materials management.According to system requirements, the system structure using the popular client/serverarchitecture, that is, C/S mode, the main form of this model is the system of managers andusers on the server side the client all the kinds of database operations, result of the operationand the database server is displayed to the client, the client and database server can beinstalled on the same computer, you can also state in the different machines in a network isinstalled, the form of freer, more convenient installation. The model also has a shortdevelopment time, lower cost and faster data transmission and so on.Business process analysis, including the flow of information, transmission, processing,storage and other analysis, the aim is to discover and solve problems in the data flow. Theseissues include: data flow is not smooth, before and after the data do not match, dataprocessing and unreasonable. Some of the causes of the problem belongs to the originalsystem is poorly managed, there are problems with data flow, and some may also investigateand understand data mapping error or an error, through analysis, these problems should bepossible to expose and resolve them.Consider the system requirements, the system can be divided into4sub-modules: systemmanagement, books management, out of storage, integrated query.The actual teaching material management system modules including the mainapplication interface, the operator management module, the password modify the module,class management module, unit information module, the module to pay book fees, book feesrefunded modules, teaching materials storage module, students receive the book moduleteachers lead the book module, books written query module and receive module.Implementation of the system and the Access database to Delphi7.0programmingenvironment for the materials management system to achieve the production and developmentprocess, the main purpose is to better grasp the use of two tools, the function of the systemitself is not as complicated as the business software and powerful, but for small businessesand organizations have the basic right. Slightly modified depending on the circumstancesmeets the basic needs. In detail the problem analysis, needs analysis, based on ensuring thesystem functions and database information to meet the general needs of the user’s daily work,with a strong portability.The system interface standard, multi-document interface design, style, consistent design,using data window, timer, label boxes and other objects, and strive to enrich the interface appearance, simple operation; set a lot of changes to remove the table-click tools, convenientand specification of the user’s operation; in accordance with the wishes and needs of the user,provide different levels of the system the appropriate information, including feedbackinformation, tips, help information, error messages, etc., and have correct the error and errorprotection.Design conditions for any combination of the fuzzy query function, enabling any numberof aspects of the structure of the query can refer to various materials ordering, supplyplanning, inventory and materials, textbooks sale, textbooks and teaching materials inventoryand other aspects of the balance sheet of information inquiries; Any structure that can be anyof the fields in the table and the combination of the query. Complex data structures linked bythe automatic data objects to handle new technology, modify a table’s data is automaticallyamend the relevant information in the table, delete a table of data to automatically delete allinformation relating to ensure no database tables redundant data.
