Research And Analysis On Contract Management System Of Sinopec Gas Station In Guiyang

Sinopec in speeding up enterprise informationization construction in recent years, gas station-building as a key construction projects in the infrastructure sector, in full control of security, quality, capital costs and duration, and many other factors, not only in professional and technical services to the path of professional development, but also in the corresponding project management to the road of informatization. In this context, for the current gas station project contains the project number, characteristics such as high security requirements, develop high efficiency, advanced performance, suitable for practical engineering applications and Enterprise contract management system software is necessary for the development of contract management to electronic and information technology is an inexorable trend overall.Paper introducing the Sinopec gas station in Guiyang project research background, project and contract management systems after the current status of research and application, according to Yun learned in3years of software engineering, from business analysis, functional analysis and design of analysis data analysis into three parts. Business analysis section, first to Sinopec has analyzed the existing organizational structure, give the organization chart and the corresponding instructions. Secondly, the traditional gas station project management business process analysis, and business process diagram displayed in the form. Finally, the traditional business process restructuring, separately from the contract, contract, contract performance and contract end four aspects through the form of a flowchart to show. In functional analysis, the system analyses the main character, this system approver main person in charge of the contract, contract review, contract basis to maintain and project information to maintain four roles. Followed by data flow diagram in the form of data flow analysis modules of the system. At last, general overview of the system architecture, divided into contract, contract, contract performance and contract end of four modules. In the data analysis, constructs the entity-relationship model, system is introduced that corresponds to the database table.
