The Design And Realization Of Integrated Information System Of Public Security Organization

At the present time, each department of Public Security Organization operates alone without the share of the information, which causes the low efficiency. What is very urgent is how to develop a set of system combining the function of office system, business system and data maintenance system which faces the grass-root unit, especially in the area where the public security Level-Three Net has been basically finished. This generally used system allows us to use the present information resources to let each grass-root unit operate it directly on the net.After the completion of the above mentioned system, it can improve the working efficiency highly, and also take the full advantage of the resources of Public Security Level-Three Net to realize the on-line office truly. It will eliminate the space gap with the users. The users can work on-line at any place at any time. They can examine and deal with their documents, check the information and make their decision. This system can also be extended and adjusted with the variation of the business.1 The Analysis of Integrated Information System of Public Security Organization1) The Analysis of Character and DemandThe Integrated Information System of Public Security Organization is the practical use of electronic political system in the public security field, which is composed of the personnel who work in the public security organization and the devices used to process information. It is an information center for the public security, and is responsible for searching for all kinds of social information. It can use the present information to analyze and make the efficient judgment, and provide information reference and valid support for practical activities in the public security organization. This system has the following features: used on net, strongly safe and obviously systematic. Firstly, the above Integrated Information System changes the original data collected and recorded by all means into the form which is required by the public security organization system, and then transfer to required inner format, so that the collection and entry of data is its basic function. Secondly the system must possess the function of resources sharing. Thirdly, it must possess the function of solid supporting.The Integrated Information System is a big network information processing software which is specially developed and made for the grass-root unit of public security organization (Public Security Branch Bureau and Public Security Organization of each county, etc. ) It can efficiently be linked to the present Public Security Net Specialty System, which can be closer to the grass root and true practice. It can also support the Level-Three Net Structure of municipal and prefectural Branch of Public Security Bureau, which starts from the local police station and eradiate each related business department. It can connect the whole business of public security centered in case system and aim at information sharing and automation of statistics and analysis of report forms.2) the basic principle of design◆P rinciple of Coherence◆P rinciple of advancement◆P rinciple of completion◆P rinciple of practicability◆P rinciple of extension◆P rinciple of safety and dependability3) The Aim of the DesignTo realize the construction and application of Integrated Information System of Public Security Organization, it should start from the point of grass root unit, and meet the requirement of the work of grass-root department, of the commanding and decision of the leaders and of the daily work of each department as well. Secondly, it can highly improve the working efficiency of the public security, saving the human resources and property, to realize the information sharing and cooperation of each department, so that it can avoid repeating collecting the same information, and reduce the manpower operation and intervention. It decreases the error rate and strengthens the cooperation working ability among the public security organization. Furthermore, the system can telnet and search for all kinds of business information, which can save great amount of travel expenses and also can ensure the validity of the information, so as to fight against the crime quickly and efficiently.2 The Analysis of Key Technology1) The choice of data-base. The development technologies are mainly divided as three types: the development of application procedure based on C/S structure; compound application procedure combining C/S structure and Web technology; dynamic website technology based on B/S structure. C/S structure is a traditional developing form, generally realized on the Two-level structure of data-base and customer terminal. It also has Three-level of Multi-level structure adding middle device, which was a standard systematic mode in OA earlier time, but it can not meet the requirement of present telenet office and motion office and is gradually replaced with the development of computer technology and internet. C/S+Web technology is used to supplement the shortcoming of C/S structure, and add Web technology based on C/S structure to realize the fetching of long-range data. But it also has its limitation, for example, it can not resolve the problems such as renewal of the data on time and upgrading the software properly. B/S structure system uses dynamic website technology, adding OA developing philosophy, which fully lives up to the requirement of on-line working and mobile working, so that it is the No. one choice for modern technology of automatic working system.2) The introduction of the technology needed in systematic study and development.SQL is a kind of query language between relational algebra and relational figure, but the function is not limited as query. SQL language integrates the function of Data Query, Data Manipulation, Data Definition and Data Control.ASP is a kind of typical server terminal website technology design technology, which can combine HTML page, script order and Active X group to build and operate dynamic and interaction server application.ODBC is based on SQL (Structured Query Language), and makes it the standard for visiting the data-base. This interface provides the maximum mutual operation, as one application can visit different data-base management system with a group of general code.ADO (ActiveX Data Object, ActiveX data object) is a group of optimized specialized object group for visiting data-base, which provides ASP complete resolving solution for visiting station data-base. ADO object operates at the server and provides data-base including content to the customer. The customer also can read and write to operate according to the designated authority backing parameter. The feature of ADO is quick operation, simple use, low consuming memory and small space of hard disk.Because ADO uses ODBC to visit data-base, so it can be connected to all kinds of supporting ODBC data-base, such as Access, SQL Server, Oralce, Informix, etc. It need to add database driven procedure before the use of ADO, and then build relevant DSN (the name of data source. ADO comprises a lot of objects, among which Connection object and Recordset Object are mainly used to control the deposit and withdrawal of data-base. It needs to build a Connection object before visiting the database, and then operate the data-base based on this Connection Object and Recordset.3 The Design and Realization of the System.The dynamic website technology based on B/S( Browser and Server) structure: using dynamic website technology with the developing philosophy of OA, which merit is it needn't install customer terminal in the customer computer. It can operate only with a compatible browser, which can fully adapt to net working and mobile working, and also is the principal choice technology for modern office automatic system. The former B/S structure is based on TCP/IP protocol, so the WWW server in the enterprise can accept the visit of Internet terminal with Web browser procedure. As an end user, every kinds of processing task can be finished with system resources only through Web browser, so as to simplify the customer terminal and reduce the cost and working load of system maintenance and upgrading which can reduce the user's general cost.Compared synthetically and combining the fact of working conditions of Zhuhai Public Security Organization, especially the fact of grass-root department, the net application combining local area network building and B/S structure, with the data-base application under Internet/Intranet Mode is relatively easy to grasp and also the cost is relatively low under present technology. Because of the poor hardware condition, the low finance, the simple facilities and shortage of computer technician in grass-root public security organization, they have no enough human property to maintain and preserve the facilities. This system is a one-step development and investment can realize different connection mode ( such as LAN,WAN,Internet/Intranet) from different site for the users to visit and operate the same database. Besides, it also can protect the data platform and manage the visiting authority efficiently, and the server data-base is also very secure. Especially after the present of JAVA cross platform language, B/S structure management software shows its character of convenience, efficiency and high-speed. All in together, it is very useful to develop B/S structure system. After the use of this structure, the whole system will operate under the browser of its own operation system. It does not use any customer terminal software, which not only saves the investment cost of soft, but also same a large amount of maintaining expenses for the public security organization. It is very suitable for the grass-root organization because of their short of computer professionals and finance, and the difficult maintenance. The disposing requirement of the customer computer with B/S structure is low. It can be smoothly operated only with the operation of the browser.
