Research And Development Of MIS Based On Browser/Server Model

As the development of information theory and computer technic,especially the rapid development of computer network,and Internet is widely built in many companies,MIS based on Browser/Server model has became the main information system for its opening and advanced structure.The B/S model can be divided into three layers: presentation layer,business logic layer and data service layer.When a user sends a request to the web server by the browser,the web server will change the request to a form which the data server can accept,then operates the database, and finally returns a result to the user.The main B/S web programming technic includes ASP, JSP and PHP etc.They have different characters.PHP has its special functions of accessing and operating database.ASP connects database by ODBC, and then completes the operation on database by ADO. JSP connects database by JDBC. If a database does not have JDBC driver program, but having ODBC driver program, Java will provide a bridge of JDBC to ODBC to translate JDBC application to ODBC application.This paper intergrates kinds of design methods of MIS, then designs a Materials Dispatching and Transporting System——MDTS. MDTS records the data flow of the materials (cement, coal powder and steel etc) from odering, dispatching, consignment, transporting to checking and accepting. The system is developed by the Php language, Apache web server and Oracle database server. The paper introduces the design of MDTS's layers, which includes presentation layer design, business logic layer design, data service layer design and security design. The paper also presents the key technic except PHP: CSS, XML and JavaScript.
