Summary:
This paper expounds the basic knowledge of information system and J2EE development platform, studies the various design and implementation links of information system, and gives the design and concrete implementation methods of public security information system. Through the development of this project, I improved my theoretical knowledge and practical ability.
On the basis of reading and referring to a large number of relevant theories and specific applications at home and abroad, this paper designs and implements a public security information management system based on J2EE platform according to the current working conditions, network conditions and the needs of practical work. The main work of this paper is summarized as follows:
1. Summarize and analyze the current situation and experience of public security information system construction in China, analyze the advantages of J2EE platform, find out the existing problems of current information system, and analyze and study the requirements of information system according to the problem system.
2. Put forward the planning principles and ideas of the overall framework of the city's public safety information system, and determine the overall structure of the system construction.
3. According to the overall design idea of the system architecture, determine the database design principles and ideas of the city's public security information system.
4. According to the functional requirements of the system, the system network deployment architecture design and software and hardware requirements are put forward.
5. Combined with the actual situation of public security work, the system function is designed, the logical structure and functional structure of public security information system are given, and the functional design of each subsystem is expounded in detail.
6. Elaborated some key modules and key technologies used. This system can provide users with an office environment under the network environment, so that the staff of all departments can handle information, submit announcements and release news conveniently and flexibly under the application environment of the system, so that all kinds of information can be fully utilized, and the office efficiency can be effectively improved, which is practical and extensible.
Outlook:
In the future system development, the information platform will rely on the police geographic information system, and complete the functions of verification information positioning, geographic correlation verification, regional investigation, geographic trajectory analysis, geographical characteristics of people, cases and institutions and four-color early warning through system transformation and standardization of address information in the database.
Realize the seamless integration of information platform and GIS; Through the information collection of extranet and internet, the integration and sharing of social information can be realized, so that the information system can serve the people.
1, realizing seamless integration with police geographic information system. Relying on the police geographic information system, through the transformation of the system and the standardization of address information in the database, the functions of verification information positioning, geographical correlation verification, regional investigation, geographical trajectory analysis, geographical characteristics of people, cases and institutions and four-color early warning have been completed, and the seamless integration with GIS has been realized.
2. Realize the integration with social resource information. Using the Internet, a large number of relevant social information resources registered by the departments of industry and commerce, taxation, labor, telecommunications, finance, civil aviation, departmental labor market, etc. are directly brought into the scope of information system integration.
And through information analysis and integration, collision comparison, backward investigation and case expansion, online regulation, related line expansion, crime trajectory description and other methods. , actively found clues to solve crimes, and improved the overall efficiency of cracking down on illegal crimes.

From March to May, the paper mainly focuses on further standardizing the format and enriching the content. Under the careful guidance of the tutor, the third draft of the paper was completed. In the later revision of the paper, I found that the problem should be discussed more deeply. I think there are many places to be improved and many articles to refer to. If there is still time, the paper should make a breakthrough.
I won't forget these unforgettable months. My graduation thesis gave me unforgettable memories. In the days when I wandered in the sea of books looking for information, faced with countless books, the most unforgettable thing was the excitement and excitement every time I found the information. In the whole process, I learned new knowledge and increased my knowledge. In the days to come, I will continue to enrich myself and strive to make a difference in my study field.
Down-to-earth, serious and rigorous, realistic learning attitude, not afraid of difficulties, perseverance, hard-working spirit is the biggest benefit I got in writing this paper. I think this is a training of my will, a improvement of my practical ability and a great help to my future study and work.
