Development, Data Management System Based On Chemical Analysis Of The B / S Structure

In this paper,through the Web database technology analysis,combined with enterprise business needs,based on the existing software and hardware environment, using Object-Oriented Analysis and UML modeling technology,system analysis and modeling is conducted,ASP.NET and C# language is used to develop a convenient enterprise applications based on the B/S structure of the chemical analysis data management system.Currently,the system as a part of the Metallurgy Product Testing Laboratory Of Panzhihua Iron&steel Research Institute Under Pan gang Group quality certification system,for two consecutive years through the CMA and CNAS certification.The main contents include:1.Web database architecture,technology and development to the analysis and comparison.2.The use of object-oriented methods for the analysis of system requirements, the establishment of a system to use UML Use Case model and domain class model.3.Adoption of the domain class model for the conversion of E-R diagram,then E-R mapping of the database tables and fields,and to establish the relationship between data tables,thus completing the system database design.4.Through the business logic of the system for analysis,the main needs of the work completed database use user-defined functions,stored procedures and triggers completed,thus optimizing system performance.5.Through the use of.NET framework provides a powerful class library,ASP.NET server controls and the C# language,developed a habit of users with similar dynamic electronic forms of mass data entry interface,and through the transaction processing ensures the integrity of data entry.6.Using dynamic forms technology,combined with CSS style sheet,client JavaScript and IE browser Print and Print Preview function of the various statements by the provisions of the Automatic Pagination print format.
