Research On Key Problems Of Enterprise Informationization Based On Web Services

Web Services is a new distributed computational model.It provides a suit of standard ways of defining, releasing and invocation of Services. Low degree of coupling services can be developed based on Web Services and it can be used abroadly in Enterprise Informationization.There are two key problems existing in current Enterprise Informationization, namely,Enterprise Application Integration(EAI) and business process construction.Some shortcomings such as difficulty of integration, high degree of coupling, poor flexibility of business process, poor interoperability and so on exist in traditional resolution scheme. Aiming at these shortcomings, Some schemes in Enterprise Informationization based on Web Services are put forward in the thesis, which have the advantage of loose coupling, widely used in various industry ,high integration ability, etc. The thesis researches mainly on the following problems: enterprise application integration framework based on Web Services, some strategies on improving the performance of Web Services, how to implement application integration efficiently, how to create dynamic business process, etc.The thesis researches deeply on enterprise application integration which is one of the key problems in Enterprise informationization. In consideration of the impacts of QoS (Quality of Service) to the usefulness of service, an application integration framework based on Web Services is improved, which imports two components, load-balanced engine and strategies on improving the QoS. Subsequently, some strategies on improving the performance of Web Services are put forward and analyzed. Based on the requirements of Enterprise informationization, a private UDDI (Universal Description, Discovery and Integration) is designed. Some problems that come forth in the development of invocation of Web Services, such as the transmission of custom Bean's object are also discussed. Aiming at the problems existing in traditional dynamic invocation of Web Services ( i.e. the use of UDDI4J and WSDL4J API to parse WSDL) in application integration, such as,fussy in parsing...
