This paper gives the basic design idea of the(B/S)-based on-line MIS by analyzing the charactreristic of the(B/S) structure. It introduces the function module and database design briefly,followed by adiscussion on database accessing technology and the active page technology of the MIS based on ASP and XML.
The Web technology development impelled Internet and its application development. Especially, Web development rapidly is impelled by active page technique and three-layer service model that between sever and client.
This paper briefly introduces how to implement connection between active page and web database in ASP by using SQL statements,and gives some source code of critical part by definite examples about database query.
By adopting to B/S browse method, using JSP active page technology, nesting JAVA language, depending on tomcat4.0 and sql2000 etc, this system achieved many electronic business functions such as the system main web, new registers registering, the newest dynamics, the products showing, individuation order basically. Many extend function interfaces such as enterprise manage, online link and network investigation are reserved.
Our extensions for μC/OS~II include kernel extension, TCP/IP protocol stack, file system, shell and function-library. At the application layer, three TCP/IP application modules are designed. They are WEB active page service, FTP client, MODBUS/TCP service.
To implement the system, the Perl, a kind of active page design language, which is popular at home and abroad, is used. The method that Perl combines with Sendmail to construct Webmail system is introduced.
It then makes a summary of technical problems encountered in system implementation, such as how to realize automatic email sending with VB, how to realize email functions with Active Page Page (ASP) and how to realize File Transfer Protocol (FTP) with VB.
This paper utilizes active page navigation diagram(APND) to de- scribe the link transition between pages, and the change of system state variables caused by submitted data is modeled by the composite object state diagram(COSD) of state variables. In an ulterior step,a more comprehensive dynamic behavior model, denoted as Web application state transition diagram(WSTD), is constructed by combining the APND with COSD.
Some disadvantages of page swapout mechanism are analyzed in Linux memory management for interactive application. A new algorithm of active page swapout suitable for the characteristics of interactive application is presented.
The document simply introduces the ASP technology and its inner components and objects. It introduces the conceptions and applications of the two main objects. Applictiond and Session, and their importance when saving the information of active pages by an internet application, designing of visitors counter.
In this paper, several connection techniques between active pages and DataBase are discussed, emphasizing three accessing DataBase techniques of ASP which are more convenient than CGI. Also the method of showing a picture in Data Base is discussed.
Internet based investigations have many advantages such as timeliness, versatility and low cost in comparison with traditional investigation methods. This paper describes a design of investigation system based on Internet. It then makes a summary of technical problems encountered in system implementation, such as how to realize automatic email sending with VB, how to realize email functions with Active Page Page (ASP) and how to realize File Transfer Protocol (FTP) with VB.
