Design Of Centralized Purchasing System For Iron And Steel Enterprises

The company procurement system after several decades of development,the basic realization of the data collection of links,but there are still some problems,resulting in some business links,the working efficiency is low,the accident loophole frequent and information feedback delay,precipitation of funds is huge,high manufacturing costs etc..Therefore,the company decided on the basis of the existing system to open up all aspects of the system to get through the system upgrade.The goal is to achieve the procurement tenders issued,bid opening,contract approval,contract signing,logistics and transport,bicycle bicycle testing,measurement,storage management,the whole process of online payment management,enhance the business data security,traceability,accuracy,to achieve the procurement business institutionalization process,standardization,electronic,open,and then realize the logistics,information flow and capital flow monitoring,strengthen management and control,to maximize the efficiency of enterprises.First,after the discussion and comparison,the system main body is used as the B/S structure,using the existing module,adding or modifying some module function,breaking the data island phenomenon,realizing the linkage of the data link.Development environment,measurement testing part mainly uses MS Windows Server 2008 operating system,Oracle database,JAVA programming language;the relevant parts procurement mainly uses MS Visual Studio 2010 and MS SQL programming platform Server 2000 database,c# programming language.Secondly,by the Ministry of information,the dynamic control part of the lead,the establishment of the project team.Relevant units of the project for a detailed research,mainly related to data sources,data processing,data whereabouts,business processes,business rights,involving the Department of personnel,etc..On this basis,straighten out the work flow,detailed data requirements,data sharing,data establish unconditional life-long responsibility,"the number of source and complete editing rules;data dictionary;data dictionary module in accordance with the division of functions,the final confirmation of the 16 modules and the detailed design of the boundary.And then,the design and implementation of different modules.In order to ensure the design and implementation of each module can meet the needs of the rest of the module,to adopt standardized module interface,code writing standard,the global variable data table stored procedure naming rules,interface design principles,etc..Then,in accordance with the three principles of test,the module operates independently,the data is accurate,the module linkage operation,the data real-time and reliable,the paper data and the electronic data synchronous operation of the module one year.Following the independent test of each module,the joint test is carried out,which is carried out from the data reading accuracy,operation accuracy,business process flow accuracy,authority distribution rationality,data storage security and so on.Finally,the work of the project during the implementation of the work,as well as the harvest and lack of a summary,for the next step to carry out the direction of the work.Since the on-line system has been running,it has achieved the design goal,but it is still improved in practice.
