Design And Implementation Of Schoolbooks Selection System

Book is the embodiment of the teaching content and teaching method of knowledge, the important source of students to acquire knowledge, the teaching of the basic tools. The materials chosen, subscriptions, construction is higher management of the important work. A standardized and efficient program selection system will be higher for the good teaching results. In the old management system and teachers to choose the process has too much autonomy, without the specification of the audit process. Most schools have adopted the credit system to teaching and can't quickly statistics the book for the students, influence the institutions of the subscriptions and issue. As school net of the popularization and the scale constantly expanding and materials to choose and subscriptions of automation and network has become the active management of the essential. So in this case, design and develop a set of book selection system based on WEB, make the system can complete the entire work of from book selection to book plan produce, combining the school book selection's management rules, which is very necessary. Through use of the system, can further comb the university book selection's process and mode, optimize its management, make it more efficient and quicker, and make the university book selection work into the modernization, informatization and networking.Book selection system mainly consists of material selected teachers selected set, teaching plans, student book, student lists, system management five major functional blocks. According to the software engineering method, the first analysis of the feasibility of the system and demand analysis, based on the demand analysis, the proposed three-tier architecture, that is: the data layer, business logic and data presentation layer, and according to the system needed to achieve the architecture of the core function of location are described and a detailed description of the system design goals. Architecture based on the guidance, the general design of the system, including the function of the system modules and database design. The core of the system tables, views and Object-oriented design class diagram were introduced to achieve, and ultimately concluded that the system's strengths and weaknesses as well as future direction of development.As book selection system's development example, this thesis uses popular application development tools ASP.NET(C# language) as the main development tool, to understand ideas and methods of this tool develop information systems, and research the key technologies, including using configuration files to connect the database, to ensure maintainability of the program; researching the general program development technologies to ensure system scalability, as similar information systems development's foundation. SQL SERVER 2005 which is as the system's back database is more widely used database for mid-scale information systems, better security and useability. Through operation of the database, familiar with writing access database, views and stored procedures statement. The system uses POWER DESINGER as data model design software, which can expediently, easily carry out database design and maintenance.System development is a practice of a software engineering, understanding development features of the B/S model software, it reducing the workload of book management personnel, to improve the work efficiency, making it more scientific, standardized, and achieved good results.
