The Design And Implementation Of System In Client Service And Its Assistance Decision

This is time that it is full of competition of intensity in the area of computer information management in the world, the computer already turn to ordinary tool, is similar to the bicycle and automobile which we cannot leave now. We should acknowledge, that it take an impregnable position in all kind of emulation who grasps more knowledge, more information, processing quickly for information, whose efficiency is high. This system is the software system which business management for the large-scale tap water merchant. It is most major characteristic of the large-scale tap water merchant that is the many users, big volume sales, service frequent, but the produce type is unitary. In this kind of situation, the paper based on Client/Server with data integrity restraint for implementation enterprise service rule, I use the common SQL SERVER to take the database, written this system with Visual basic 6.0. Microsoft Corporation's Visual Basic 6.0 is the kit for Windows application program development. It is the object-oriented development kit to be easy to study, to be easy to application, to apply widely in present. Visual Basic provided massively has provided, these controlled is possible to use in designing the interface and implementing each kind of function, it reduced programmer's work, also simplified the process to interface design, thus it enhancement validly efficiency and reliability of application program operating. VB is a relative good selection for applying the system. I hope to give help to the large-scale tap water merchant to management with the system. Analyzes form in the tap water merchant control function, there are three aspects demanded to the tap water merchant altogether: controlling of consumer, controlling of tap water, controlling of sale. Therefore, this system designed from three aspects above, is to carry the function. This set of system designed from reality, is to solve the actual problem truly, in aspect and so on consumer control, water sale, staff achievement statistics has provided the rich function, through uses this set of systems, lets person in charge of the large-scale tap water enterprise having quite clear understanding for the entire enterprise's service stream, the information flowing and the fund stream, thus can carry on the analysis and decision-making well, the more valid check cost, the regulative enterprise resource , through controlling the enterprise entire process monitoring and the control , to obtains the higher consumer degree of satisfaction, expands the marker share unceasingly, makes strongly the enterprise dose in a big way. This set of system have the characteristic extremely in the aspect of the water sale and control the fund to return. Through this design paper, the enterprise must make quite transformation on the internal management to cause the specific service flow the software system like this adapts. Through design this set of software, detects original service existence many holes and the insufficient place in the service investigation process, for example: In the link of water ticket sale, the original service has not mechanism in the sale of water ticker, nobody is clear how much water ticket in each one consumer, also nobody knew whether the consumer using water is buyer, through using the management system in the paper design, the enterprise can accurately keep abreast of the water ticket sale situation , whose ticket use consumer is who, how area the genuine consumer's distributed, the situation of the bucker take back, the achievement of water supplies, whether exists runs braves dripping of a water clock phenomenon an so on, and all is clear. Has also spend the very time in the software usability design aspect, has all provide the fuzzy inquiry and screening function in each input interface, maximum limit reduces operator's input difficulty, to makes the input efficiency to enhance several time through these skills designs, and maximum limit has guaranteed the input data accuracy. In the aspect of service stream design, the original service flow open loop design, changes to de closed loop design, it all carries on the comprehensive control and the monitoring that start from sells the water ticket, to supplies water the faction labor, draws water, delivers, barrel taking back, through this software, causes the sale with a clear goal, cause the production implementation to produce by the caging,cause the staff achievements inspection well attested, making the entire enterprise achieves the service stream, the information flow an the t hing flows to gather one. Through the use the system designed in the paper, can reduce greatly the time of process consumer subscribed water, moreover reduce the user information which the user provides through looks up the consumer information, like the user address, the contact method and so on, enable the consumer to have kind of felling kindness, therefore, to monitor the time and mistake rate of the water subscribe and deliver, enhanced the consumer degree of satisfaction, at same time, enable the consumer the loyalty to obtain enhancement, enables the enterprise to check the market firmly which holed already, to reduced greatly consumer's lost rate. In the aspect of software design, massively uses the middleware, to reduce the operand to the threshold in the front with placing the main operation in the background processing, also fell network flowing to has been lowest, to solved the problem greatly that the enterprise existing computer equipment is quite obsolete. Through this graduation project, I study and grasp the method of exploitation on the database system, deepens understanding to the database knowledge, exercises the ability of solution accrual problem independent, and understanding deeply in caculatting and the network, the network programming, the large-scale database and programming language Visual Basic 6.0 , has grasped the many kinds of investigation and study method and the system analysis and the system design skill, at the same time, also had a deeper understanding to the existing actual service, will be extremely big to the next supervisory work help, also had a deeper understanding and the understanding to the computer in practical work application, I will be able in the next work, even more to take application with the computer , make our company get level a yet higher goalon of computer application .
