The Requirements Analysis And Design Of The College Education Assessment System

In recent years, with the rapid development of the Internet and personal computer, more and more enterprises, institutions and government agencies began to use computer networks to replace the existing office management mode, or as an auxiliary means to make up for the deficiencies in the traditional way.The education merit work at each beginning of academic year in Heilongjiang University, is a short-term, high-intensity work. The school within a month of the tens of thousands of students and teachers, apply and audit the merits of last academic year. Assessment work by manual before completion, fill in all forms and then submit approval, time-consuming.In order to solve this problem, this paper proposes a kind of solution, we design and implement a suite of online education assessment system, to replace the original artificially type process, you can save a lot of workload, only need several administrator is responsible for maintenance and examination and approval procedure last stage in artificial audit can, estimate related work time can be compressed into two weeks of less than, greatly improves the work efficiency.In order to ensure a system reliable and usability, this system adopt the latest Java EE 6 standard of development, make full use of its provide security mechanism and distributed support, and adopt standard realize, in order to make systems facilitate migration, reducing effectively the system operation and maintenance costs.The whole systems are based on Java EE each layer to development, page 6 layers use the JSF 2.0 standards, its MVC style realization ways can isolate data and display, increase development efficiency, reduce maintenance costs; Logic layer use the latest version 3.1 EJB standards which programmers don’t concerns, and the network transmission concrete realization ways, will be more focused on business logic; the realization of And lasting use popular ORM layer is a, jiangjia JPA framework, shielding underlying database standard 2.0 heterogeneous, simplify the data storage and query.The each systems layer are based on Java EE6 to development, page layers use the JSF 2.0 standards, its MVC style realization ways can isolate data and display, increase development efficiency, reduce maintenance costs; Logic layer use the latest version EJB 3.1 standards which programmers don’t concerns, and the network transmission concrete realization ways, will be more focused on business logic; the realization of And lasting use popular ORM layer is a, jiangjia JPA framework, shielding underlying database standard 2.0 heterogeneous, simplify the data storage and query.This paper introduces the education assessment work process, and calculated system requirements, the authors describe the way of designing and realizing the system. By test operation shows that the system can effectively reduce the recommendation of human and time cost work, greatly improving working efficiency, system operating normally, can officially use.
