| As information technology and the rapid development of network technology, in business management information, the degree of automation in the ever-deepening. Among them, the enterprise contract management as a day-to-day business management of an important part of the contents of it is essential for managers, a good enterprise contract management system should be able to provide users with adequate information management and decision-making. This article discusses the enterprise contract management system for the public, good compatibility, the system has some scalability, maintainability, and standardization, and automation is achieved by the system development goals.The traditional contract management system is a manual input as an alternative from the traditional data records generated by these systems can not be the face of corporate support for the intensive use of information technology requirements The system uses VISUAL C + + + SQL Server2000 technology enterprise contract management system. In the system using SQL Server2000 to complete the data query, analysis, application VISUAL C + + language programming, through the system, users can query the enterprise contract, entered into, modified, and other functions.Visual C + +6.0 is not only a C + + compiler, it is a Windows operating system based on visual integrated development environment (integrated development environment, IDE). Visual C + +6.0 by a number of components, including the editor, debugger, as well as Wizard AppWizard, Class Wizard Class Wizard, such as development tools. These components through a component called the Developer Studio integrated development environment for the harmonious.SQL Server2000 is based on the SQL Server7.0 expansion of the product upgrade. Inherited a SQL Server2000 database software design and engine areas, has become a new generation of Web applications and analysis of the best database solutions. XML and HTTP to provide its full support; provide partition load and ensure that the characteristics of the time; take full advantage of the Windows 2000 features, including support for Active Directory (Active Directory) services, supports up to 32 processors and 64GB of memory. SQL Server2000 with higher stability and reliability. SQL provides a number of task orders, relational database of all the common language, all prepared to use SQL procedures can be transplanted. Enterprise contract management system is a typical application of the database development, from data management, basic information management, contract management, contract management and system management components 5. Each component, including its own can achieve the corresponding functions.1. The basis of information managementThe module is mainly for enterprise contract management in the sector of information between units of information, project information, such as the effective management of information and the realization of different conditions on the data query.2. Data ManagementThe module is mainly for contract management system for effective data management, data backup and recovery, to prevent important information because of the contract after the man-made mechanical failure caused the serious consequences of data loss.3. Contract signing managementThe module includes the assessment before signing the contract, contracting, contract changes, such as sub-modules. Review the contract before signing the contract before signing the main record of the assessment information, against the signing of the contract to manage information in support of printing. The main module to complete the contract to add, delete, query information on the functions of the contract in support of printing. Contract to be completed to change the module to change the information on the contract to add, delete operations, and support for different conditions of the contract to change the query information.4. Contract implementation managementThe module includes modules for means of payment and breach of contract claims module. Means of payment processing module can be achieved means of payment for contract information to add, delete, query and other functions. Breach of contract claim can be sub-modules of contract claim for breach of contract information to add, delete, query and other functions.5. System ManagementVisit the main module of the contract management operators and operators to effectively manage passwords .The system uses a structured analysis method (Structured Analysis, method referred to as SA), top-down, and gradually break down the system data flow diagram for the abstract. Gradually break down in processing, but also the data level decomposition, the formation of a number of levels of data flow diagram. System data dictionary is a collection of various types of data description, including the data item, data structure, data flow, data storage and processing of five parts, this paper presents the system and descriptions of important data.The concept of structural design is the key to the whole database design, data model is a common basis, it is more than the data model independent of the machine, more abstract and thus more stable. In this paper, the system is given in the overall information system ER diagram and ER diagram, ER diagram will be converted to and choice of DBMS products to support the data model with the logical structure, and then such a data model to support a variety of DBMS to compare, select the SQL Server 2000 database server as a background. On this basis, to determine the physical structure of the database, and an evaluation of the physical structure, the design of the system to ensure that the database can run on a variety of services a shorter response time, high storage space utilization, transaction throughput, and is Optimization of a database structure.It also accepted the operation of the system environment, as well as hardware and software interface. As well as the design of error handling.This article also gives a systematic analysis of test results. For the input and output test test ruled out the possible errors, and better fault-tolerant performance. The availability of the system reached the target.Finally, the full text of this article are summarized. |
