Realty Charge System Based On SOA

SOA (service-oriented architecture) is a kind of advanced architecture in the industry including all types of systems which can help span long distance and collaborate with business partners so that the system stability strengthened, operation cost reduced and efficiency improved.From supply and demand view,SOA have stepped complete extension of technology and product.The folowing 5 points on SOA need to be focused. Firstly,user approval.Secondly,user application and enhancement .The key point is application launch.With the time flying of 3 years,SOA product and solution have been put into market,also have a successful test application at domestic core fields.But currently typical case is less.Thirdly ,SOA needs comprehensive implementation from domestic manufacturers,media and suppliers outside of media.SOA has become core topic concerned and pushed by software manufacturer IBM,BEA,SAP and Oracle.Even international and main software manufacturers aim their strategy at SOA. Fourthly,Prodcut standardization or technology criterion integration.During the development of SOA,the technology,standard,product and method model adopted by typical providers is different.It's difficult to image for future application and development of enterprise users.Fifthly,SOA technology and product development.Its development speed is prompt.And It's reported that as an important and new technology trend,long term produt pushment is an essential if pilot IT field's development.Based on SOA concept to infrastructure system design when designing SOA building.The text realizes HTTP protocol at the circumstance of typical SOA.And introduces how to save cost and raise work efficiency for enterprise based on SOA frame.SOA sets up a direction and flag for us.During current China information development,It will take an important role for enterprise information if ponder and implement SOA.In the design process based on the SOA house Information system, it is designed as SOA as much as possible. And the thesis based on typical SOA implementation (HTTP agreement), introduce how to reduce cost and strengthen efficiency according to SOA structure. SOA shows a direction and structure instead of a technique. It must be considered in the current stage of Chinese enterprise information development. In the future, SOA plays a vital role in enterprise information development.AdvantagesFirst, system management and implementation advantage . Using the existing assets . The method is that the existing assets could be dressed as the service which provides enterprise function. The organization can continuously obtain value from existing assets instead of constructing from the beginning. It's easier to integrate and manage. The influence of infrastructure and implementation change will be minimized. Because the complicacy is isolated, when more enterprises collaborate and provide value chain together, it would be more important.To implement integration faster . It can reduce software development cycle to use existing components and service. The new business service would be developed faster and moreover, it permits the organization to response quickly according to the change and shorten the development cycle .To reduce cost and increase repetition . The enterprise can publicize the business service as loose coupling way, and can also use and assemble service according to business requirement.SOA business process consists of a series business service which can be established, modified and managed to satisfy the need in different phases. Second, technique advantage .Independent location provided and independent agreement. The service doesn't need to relate to a certain system in a certain network and it can use a method similar to url. The communication structure which isn't related to agreement can realize the code repetition. The packaging of Webservice doesn't relate to implementation so lots of methods can be released through Web service.It can be changed to web service after finishing function development. So the development and operation of applied program could be easier, and the service management could be more convenient.The loose coupling system makes the integration easier. The integration includes applied program, process and complicated service aroused by less complicated service. It also provides authorization and certification service to customer and realizes all the security functions through service interface which shows the advantage over tight coupling.DisadvantagesSOA structure isn't universal, so it must be paid more attention when used in a large enterprise.Security issue. If it is under shutout because of information system, the loss would be more than 100,000 yuan. In the current, the enterprise information development trend is that IT combined with business more and more, In other words, business depends on IT more and more. So if SOA couldn't solve the security issue, the development would be limited significantly.Performance issue. Though it is simple based on HTTP service, part of performance would be sacrificed. So it is a trial for large scope application. ImplementationOn implementing SOA ,Maybe come across the following challenge:Point 1.Selection of SOA platform .User should consider platform ,implementation method&channel and supplier when choose SOA product and technology.Point 2.Make a sufficient analysis for user business from SOA view. Implement SOA is a long process,such as service package,business procedure and data management,in one word,meet some challenge on implementation.Point 3.Technology and experts issue.Implement SOA will cause a quick return and is a main trend.I am sure SOA march step in China will be wider and wider with the development of network bandwidth and technology.
