【文章內(nèi)容簡介】 acilitate rapid decisionmaking, and effectively avoid the losses of enterprises. (4) Comparison of data traceability. As the B/S structure of the data is stored centrally, so the head can be directly traced to all levels of branches (branch, store) the original business documents that can be traced back to see the results. Most C/S structure software that is different, in order to reduce the data traffic, just upload the data center report, can`t be found in the headquarters of the various branches (branch, store) the original documents.(5) Service response time parison. Business process, business model is not static, with the continued development, will inevitably continue to adjust. Software vendors of software do not perfect, so software products that have been deployed to maintain, upgrade is normal. C/S structure software, because its application is distributed, the need for each installation using the node, so that even very small bugs have a very long time to redeployment, redeployment, in order to ensure the program version consistency, must suspend all operations update (IE shock Updates), its services, the basic response time cannot tolerate. The B/S structure software that is different, the applications have focused on the headquarters server, the application node and did not have any place update is all the application updates can be done fast service response. (6) Comparison of web application constraints. C/S structure of the software only for internal users or LAN broadband users (more than 1 trillion)。 and our B/S structure software can be applied to any network (including dialup network access method), particularly suitable for broadband access are (for example, ICT Group, some of Di branch alone can be the normal telephone line using the software system).4. B/S and C/S structure, the difference betweenClient / Server are built based on the LAN, Browser / Server is built based on the WAN.(1)Hardware environment is different (1) C/S General to establish a dedicated network, a small area in the network ambience and through dedicated server between LAN provides connectivity and data exchange services. B/S based on wide area networks, and need not be a dedicated network hardware environment, such as telephone access, rental equipment, information themselves, there are more than C/S greater scope to adapt the general as long as the operating system and browser on the line. (2) On the safety requirements are different: C/S for the general user base is relatively fixed on a strong information security control. Usually highly confidential information systems by C/S structure appropriate, can be B / S part of the publicly released information. B/S based on over wide area networks, the relatively weak control of the securityoriented user base is unknown. (3) On the procedural framework for different: C/S program can pay more attention to process, multilevel permissions can check on the system speed can be considered less. B/S on the security and access speed of the multiple considerations, based on the basis of need for more optimized. Than the C/S have higher requirements, B/S structure, procedural framework is the development trend, from the MS39。s. Net Series BizTalk2000Exchange2000, a prehensive support network set up the system ponents. SUN and IBM pushed the JavaBean ponent technology, so that B/S is more mature. (4) Software reuse different: C/S program integrity can be considered inevitable, as the reusability of ponents in the B/S request for ponent reuse is good. B / S on the multiple structure, required a relatively independent functional ponent. They can be reused relatively good. Tables can be bought as recycling, rather than doing a table in the stone wall. (5) Maintain different systems: System maintenance is the software life cycle, spending big, very important. C/S program as a whole, we must examine the whole deal with the problems and the system upgrade is difficult, perhaps do a pletely new system. B/S ponent position of the replacement of individual ponents, achieve a seamless upgrade the system. Minimize maintenance costs, user download from the Internet itself can be achieved to upgrade. (6) Dealing with different issues: C/S program can handle the user plane fixed, and in the same region, the demand for high security requirements, and operating systemrelated, should all be the same system. B/S based WAN, for the different user groups, geographic dispersion, which are C/S can`t be done, the relationship between the operating system platform, minimum. (7) User Interface different: C/S multiple is based on environment of Windows , performance is limited and generally require a higher on the programmer. B/S based on the browser, the
