The Design And Implementation Of Contract Reserve Management System For China Petroleum&Chemical Corporation

Under the condition of the market economy, refinement of the social division of labor causes that enterprise production and operation need more and more external dependence. Contracts, as a legal form of commodity exchange, play normative role in the compliance activities between production and business activities of the enterprise and the enterprise. Contract preparation management is an important content of the enterprise management foundation work. It can helps standardize signing and performance of contracts by strengthening management and can effectively prevent risks, optimize management, reduce costs and improve efficiency. All this time, Group Company treat the contract preparation management as the most important legal work, focus on continuously improving the legal management level. After the responsible person of contract sponsoring department and contract counterpart have reached an agreement about the information negotiation like contract terms, the responsible person should land system to initiate contract before signing the paper contract, and this step is so-called contract preparation. In order to accomplish the preparation work of contract signing, and optimize the process of contract signing, we design and implement the contract preparation management system of the China Petrochemical.The contract preparation management of the China Petrochemical is a management system based on Web development, uses mainstream IT to design highlight management functions, and it is more powerful in query and can provides a comprehensive solution to help mobile users to get access, and add security management functions in information publishing and database technology. The contract preparation management system of the China Petrochemical uses the Java language and JSP technology, is based on SSH (Struts+Hibernate+Spring) framework design and uses SQL Server2005as the database server, so that implementing four functions, as follows:general contract conclusion preparation, important contract conclusion preparation, contract basis management and project information management. The system was designed and analysed by design ideas of software engineering, and we use UML standard modeling language to describe the design and implementation process of the system. The UML standard modeling language can clearly express the design ideas of the system and using the idea of object-oriented to analysis and design. We summarize functional requirements of the system by the use case diagram and use case analysis table of function specification. As for detailed design of the system, we describe the architecture of the system functions by the contract preparation management system of the China Petrochemical; introduce the design ideas of system’s technical architecture; describe the overall network architecture of the system and the final implementation procedure of system. We mainly describe the detailed design producer of the system through the module design and sub-module function timing diagram, introduce the system database design, indicate the logic relationship between the various entities of the system by E_R diagram. The fourth chapter is the implementation phase, and it describes the system functions by the system development environment and software environment configuration, and accompanies by code of some functions of the system modules; and use activity diagram to describe the process of perform operations with the help of system functions; finally we introduce the necessity of system testing and describe the system functional testing process and final test results.The contract preparation management of the China Petrochemical is birth under the current environment. By strengthening management and standardizing signing and performance of enterprise contract, we can effectively prevent risks, optimize management, reduce costs and improve efficiency, and provide the basis for technology departments at all levels to sign contract. And the system provides efficient and accurate service for units and departments to preparing contracts and reduce the burden on the appropriate departmental staff. The contract preparation management of the China Petrochemical helps the contract preparation transform from traditional manual way to modern information technology way to improve work efficiency and standardize contract management. Networked and dynamic management of contract preparation information lay the foundation for comprehensive collection of contract information data and standardize management of contract information.
