Abstract

In recent years, with the accelerated pace of military construction, military equipment is constantly upgrading will optimize the troops and equipment management, put on the agenda the increasingly urgent demands of troops and equipment information construction has become an extremely important part of military information. This is one of the prominent and highly representative vehicle management forces, army vehicles must be done to supply timely, accurate allocation, well documented, and the only way to fully play a fundamental role in the transport of safeguards, the vehicle management information technology has become very important. Force vehicle management features are as follows, the large number of vehicles, the high flexibility of the operating site requirements, flexible business requirements. The rapid development of modern science and technology, information technology and communication and technology, a great impact on how people work and live, this to bring rare opportunity to Force vehicle management, and also it is facing unprecedented challenges. Both opportunities and challenges, and this requires us to seize the opportunities and difficulties, the use of information technology to improve military vehicle management, to improve the transport of troops support capabilities, this is also in line with the trend of military modernization. From the above, we need to combine the modern information technology to build a new police vehicle management information system, This article is to address this issue commenced, operating locations and flexible with B / S model to solve the problem, solve system-level J2EE tiered standard coupling DI design patterns to solve the problem of flexible business logic. The which database Select SQL SERVER2000, database table design in accordance with the actual needs, and three paradigm based on a relational database design, do reduce data redundancy to ensure data integrity when CRUD, and this made a detailed introduction. The data table the persistence layer design, persistence layer is responsible for the upper and lower transfer data objects, that is, to pass over the top operating package object deconstruction and reflected to the database table, while ensuring that the data from the database encapsulated into data objects to extract the correct data in the table, the data object is passed up the layer design, we use an ORM tool Hibernate In this paper, the design and operation of the process of doing a detailed description of this design approach for database operation statement pulled helpful in the business logic layer. Persistence layer design, the paper began to design the business logic layer, the layer using the DI design patterns called decoupling between the business logic module, its working principle is to call the relationship of the business logic written in the configuration file, the configuration file loaded when the program starts change or increase, when the call to the appropriate business logic module, depending on the value of the configuration file to instantiate the corresponding business logic objects, that the so-called dependency injection, this can be loaded at runtime object, reduce system overhead, and is conducive to business logic . Persistence layer design, this paper carried out the design of the presentation layer, the layer of paper to do a brief introduction, the MVC pattern, using Struts tag control page logical page logical call business logic, user operation encapsulated into a POJO up and down the web server using Apache, to meet the application requirements. Vehicle management system to achieve a set of forces according to the principle of the above ideas in this article design and test run in the barracks, basically meet the requirements of the Force vehicle management information system has completed testing in the trial stage. The rapid development of modern science and technology, information technology and communication and technology affect how people work and live in this era of technological change every day, we work also with the times, the system future work is to wait for the system when the new demand down, verify that you can explore more flexible to changes in the business logic and security, the following user level role clearly defined and developed classification verification module, based on the different roles assigned to users operating authority, to enhance the security of the system, and another to do more work on the database backup.
