Production Information Dissemination System

This thesis is a design narrating of a computer management project.It mainly expatiates the background of the project,system investigating, total structure design, the detailed design of the main module and system evaluation.1,the background of the projectRecent years, along with the quick development of economic globalization, the business enterprise is vigorous of the competition put forward a higher request for the business enterprise management of science, information-based degree of high and low have become the modernization level of a business enterprise with comprehensive the important marking of real strength.In order to solve the request that information share, information covariance and production control etc., a vapor limited company truck of the liberation car factory production department put forward construction production an information to release the need of system.The item development group expects according to the front to the truck need and total and strategic target of the factory production department business do of overall understanding, aim at a customer need to develop the truck factory production information to release system item with business enterprise present condition currently.The truck each car of factory production line of produce plan and produce the information be all released by that system, and carry out solid hour yield supervision, cease work statistics, the production newspaper, production data statistics and produce the species record go into and statistics etc.14 functions, for produce an information to release, supervision with gathered covariance to provide terrace.2,The system total frame designThe .net terrace of the system adoption, the database development of the SQL Server, the dynamic state born and main page.Can carry out software to install easily of change with the renewal of the function mold piece.The system is whole to adopt three layers of structure:Database layer, logic layer, performance layer. Under this kind of system structure, the business logic of traditional performance layer and data layer, will concentrate business logic a layer a management. Increased customer to carry in general use, independence of applying the procedure so, also avoided a data layer swollen saving process with trigger a machine. Also reduced software to install the difficulty which renews with edition moreover, needed to be installed and renewed a business layer enough.3,The corpus mold's piece's design thoughtsFirst according to need analysis customer operation, write saving process.Then carry on the design of type.According to the abstract design of the customer role, the principle is the object of customer operation in the system of reflect and shoot, so type mostly the data form reflects and shoots in the system, the attribute of type be the word segment of data form,all give it and read to word segments and the method for writing.The method of type is a customer logarithms according to of operation, adjust to use for the sake of the convenience, all define the methods static of.Use Visio as the tool of the design data form and type, lead finally.CS document.Returned to each type to write to gather a type in the meantime, conduct and actions returned of gather as a result.At design, quoted from a Microsoft to provide of the data interview SQLHelper.cs.The design of completion edits and translates to pass through a csc behind, born.Dll document.At design of in the meantime, also need to write an unit test, what to use is the tool Nunit of the unit test of in keeping with.NET environment, adoption of is white box the way for testing. Write to control a piece finally.Ascx, complete the design of customer interface.4,SummaryThis system interface is friendly, beauty, the usage is convenient, easy to learn use easily.Lowered consumedly to the request of user calculator knowledge, suited for the information system of business enterprise inner part construction specially.This system adopts B/S the way development of the structure currently.Releasing sex information allly all adopts the B/S method design, can carry on an information to release through the IIS(Internet information service) in the Windows system completely, the customer can carry on the information which visits to authorize an interview in the system through a browser. Because the B/S of this system structure, the customer can connect in other chains that the business increases this system in the system directly.
