Research And Implementation Of Telecom User Data Inquiry System Based On SSH2

The Telecommunication Query System for User Data is to construct a system as an attachment to the accounting system for the operators, which is a new system with functions of automatic collection, automatic transmission, synthetical inquiry, intelligent analysis and application, and presentation of pictures, so as to meet the demand of detecting modern technology, enhance the efficiency of solving such various illegal activities as economic corruption, violence, smuggling, abducting, drug trafficking, etc., and maintain the order and discipline of the society.The Telecommunication Query System for User Data is designed on the base of modern software project and completed step by step. Firstly, it made survey and research on the functional and non-functional demand of users, modularized these functional demands. In the process of designing, the overall structure of software, data collection, functional modules, input/output, external interface, error handling, etc. were carefully planned. The design work was done through object-oriented method in line with users' business processing data flow, i.e., the sequent action of data col ection, standardization, storage, query and analysis.The Telecommunication Query System for User Data adopted the large database of ORACLE and made a program to the relevant hardware of database server in line with online database capacity. When it came to the database design, the present study has respectively designed the modules of data collection and storage, data query and analysis of charts carefully, realizing the functions of integrated query, intelligent analysis. The system implies DQETL into data collection, which ensures the accuracy of data and detecting modern technology. The optimization of SQL query is the guarantee of the good function of the system. The Query System realizes the input of data of twodimensional code through the external interface, which is beneficial for the integration of the delivery of all the relative data.As for the security of the system, relevant solving schemes have been respectively offered to it from the perspectives of physical security strategy, application system security strategy, network security strategy, security management strategy, etc. And, according to the system characteristics were adopted cold standby as well as application- based database backup/ recovery strategy.
