Self-service System For Restaurant

With the developing direction of the mobile communication technology of field. Present Hotel systematic technology has been already very ripe, can offer the new business of the high speed in more one. This paper mainly study the access way of FireBird and JAVA lanuage under the ministrant platform supporting various kinds of restaurant.This systematic have fetched a kind of method of dynamic distribution of channel called Dynamic partition scheme , this assign main thought of tactics is to count and divide individual total channel of district into different areas, every area have its special-purpose among, some channels are reserved JAVA lanuage exclusively for new/handoff voice calls and FireBird database for new/handoff data calls.According to the scheme,we define the access way of voice calls will be firstly arranged into voice-only-area.if there is no available channel there,it should be directed into shared-area.On the other hand ,data call will be firstly arranged into data-only-area.If there is no available channel there,it should be directed into shared-channel.The systematic is B/S Model.Let be the steady probability that there are new voice calls,handoff voice calls B/S and calls in the system. The JSP higher efficiency and safety. The ASP in source code form to explain way, storage, all need to call the ASP page source, high efficiency. In addition, the vulnerability has made many IIS website source program, including the great exposure before the website with ASP, ASP program development was downloaded to all.The JSP in performing before compile bytecode byte code), (from Java Virtual Machine bytecode Java Virtual Machine (explain implementation, high efficiency, explanation of the source code, The server and the Cache bytecode mechanism, can improve the bytecode access efficiency. The first call JSP page might slower, because it was compiled into a Cache, then much faster. At the same time, the JSP source program is unlikely to be downloaded, especially JavaBean program can not put the list of foreign.The JSP components (Component) way more convenient. Through the COM to expand the ASP file, such as the complex function uploads and send email and processing or complicated computation isolated become independent recyclables module. The JSP through the same function realization JavaBean expansion.In the development of exploitation, COM than JavaBean complex and tedious, learn ASP, but not simple to develop COM. But much more easily JavaBean from above, this can be seen in the sample development JavaBean is very convenient.In the maintenance, COM must register in the server, if modified COM program, you must register, even must phone and restart. No need to register, while JavaBean CLASSPATH on the list contains. If JavaBean change, and now also need JSWDK Tomcat closed and re-lauch (but not off), but the developer has promised in the later versions will do not need server.ln addition, the OOP JavaBean is completely different business can be conveniently processing function set recyclables object repository, such as user access control, email autorespond etc. The ASP now applies only to NT and IIS. Although Unix under the plugin ChiliSoft to support the ASP, but the ASP function of itself, must pass through the ASP + COM combination to expand the COM realization, Unix up very difficult. The JSP are different, almost all Java platform, JSP JavaBean + support in all the workbench fake. Through a plug-in under IIS NT can support the JSP. The famous Web server has been able to support the JSP Apache. Due to the Apache, widely used in the NT, therefore the Linux unixes and a wider range of JSP operation platform. Although the operating system now NT, but a large market share in the aspects of Unix is still server, and new advantages of rising Linux. But to deaden.From a platform to another platform, JSP and JavaBean don't even need to recompile, because the Java bytecode are standard and platform irrelevant. Then write out the steady-state balance equations,work out every by a recursive technique de probability,the data call blocking probability and the totle channel utilization can be getted. Analyse the systematic parameter, summarize the systematic advantage and shortcoming ,then present the numerical results value into B/S system.In all, The systematic obtaining all the steady state. By the way,we introduced another scheme called scheme.Compared the two schemes and we can Run the systematic parameter, summarize the systematic advantage and shortcoming in all way.
