Design And Implementation Of Contract Management System In Liaohe Petroleum Exploration Bureau

The oil-field reorganization changes the system hereafter, LIAOHE PETROLEUMEXPLORATION BUREAU the insider an organization proceeded the very big adjusting,contract management work too because the second class unit increases, business enterprisemanagement work of enhance, unit workload again contain aggrandizement, working thecontents become more and more. It is old to work the way is already not well to should the demandthat ex- contract manage work. So must develop the contract information management system ofthe calculator to replace the artificial management method, from but increase the contractmanage the efficiency of the work.Investigative and main contents in thesis is function that distribute type technique, thetechnique of JAVA, face to the object plait distance with database etc. technique, analyzed thesystem in a specific way to divide the line, the function describe, the function request,customer require with, proceeding a design, data construction design, logic constructiondesign, among them emphasized to complete the contract the management the system the insidethe data layer, business layer, Web means that the layer realizes in a specific way.A characteristics for combinative oil-field unit scattering about doesing not concentrates,adopted the customer to separate with database mutually of three layer system construction. Theapplied procedure that realizes pack the system function in applied layer, for the maintenance ofthe system with renewed to bring the convenience, under third layer construction systems,adopted the JAVA plait distance language with the environment of development that relate to thetype database, ask for help from to face to the object design with unify to set up the moldlanguage(UML) etc. software engineering method, complete the system analysis to design withthe system function. Because the server of Web carries the demand provides complicated variousfunctions that contract manage with even have to hand over the with each other sexual request,using the JSP, JAVABEAN with the technique, database adoption SQL SERVERdatabase, the data distributes the adoption concentrates way management.Lesson a contract for main research Web environment descending managementsystem. Opposite in traditional C/S, Web application procedure deployment convenience, supportthe sex better. TheliaoHe petroleum explores the bureau information chemical engineering makes to overlay the each corner that oil-field produce gradually. Explore developments of the bureaubusiness enterprise net along with the LiaoHe petroleum with the technical development incommunication, all levels unit a basic term for setting up bureau area net, having calculator ofmake use of proceeding contract managing. Pass to establish the contract the management thesystem, enable the all levels contract the management the section on time acquire the contractinformation, from but increase contract management work efficiency.Makes use of the investigative technique in this text method, the contract managementsystem that develop, now already in the LIAOHE PETROLEUM EXPLORATION BUREAUthe organization and second class unit contract management section success that explore the bureauis applied, realizes the oil-field business enterprise contract signs, change and turn to let,relieve, dispute, break contract, settle accounts and terminate to wait the process to managecompletely, and realizes the related information of management of contract assistanceannounce, contract set debt, contract text this, contract search, contract statement ofdynamic management, increases the efficiency that contract manage the work, make oil-fieldthe governor controls the contract circulates the development, the energy that throw in people ismorely the business enterprise of management management.
