Technique of Integrating PB Applications in Web

Web technique, which changes the exploitation and the implementers of enterprise's application system, is an important part of Internet/Intranet.Database technique is the basic tool of information management and effects on the basic core.Metabolic operations need new capability requirement for database application.In pace with the competitive superiority of Internet/Intranet, enterprise affronts the new operation challenge.So the combination of Web technique and database technique-Web-db, emerges, as the times require.PowerBuilder has mightiness exploitation function for database and lo ts of big model enterprises have used it to exploitat management information system.So, it is a significative research task in the field of computer application that how to use Web technique to include PB application software, traditional MIS and intrinsic invest in Web.It can realize the conversion between traditional MIS exploited using PB and Internet/Intranet information system.The research will exert greatness potential of information resource. On the basis of the meaning of Web-db and the point that integrating Power Builder application software in Web, this article brought forward three kinds of solutions.One is to use browser to visit database in Internet.Its typical representation is commonality gateway interface and API technology.The second is dbms jointing Web at first hand regarding Web as base.Some manufacturers enlarge data type of database.All of the Web data types are regarded as dbms internal data types.The third is enriching local warehousing using Web resource.This method studies and uses data resource, including content in database and net page.Warehousing on Web and data mining on Web in literatures belong to this work.But, choosing which method to realize integrating Power Builder applications in Web needs to consider some aspects, including exploitation environment, client environment, the CPU capacity of server, the traffic and memory capacity of net. This article gave an ex ample of power supply bureau of Wuhan, based on it's net's characteristic and enterprise's characteristic, analyzed application's needs.Decomposing Web database application is as follows:dealing with complicated enterprise interior information and application, keeping existing system integrality and safely, and it's performance;issuing enterprise's information and data out the enterprise. This article put forward how to realize it.Firstly, choose Web server.The Web server needs kinds of sustain, face multimedia, suffice transiting application in Web,must have the tools to create net spot and manage it.In this solution,we choose IIS as our Web server. Secondly, using Web.pb, transplanted enterprise internal manages information system to Web.And listed its system framework.Here an example about how to include Intrinsic Power-Builder application in new application is given. Thirdly, using ASP technology issued internal information and data of enterprise.This can obtain really thin client and high performance. This system can achieve reliably affairs manage and rationalization.It has powerful database in the back end, deals with relational affairs, servers a mass of client s.Simultaneity, it changes old operational pattern of enterprise system.
