Research And Implementation Of Input And Output Interaction Handling Mechanism In Bcsep

The emergence of Web services to enterprises had brought great business opportunities. However, on the Internet a growing number of existing Web services with simple function have no connections between them. These services are often unable to meet the needs of practical application, and the number of Web services need to come together to complete a more complex task. Under such circumstances, the researchers proposed the concept of Composite Web services. Independent Web services composites to composite Web services together to form a more powerful system to bring greater business value. How to achieve the combination of services becomes a hot research.In order to make a better application of Web services-oriented business, the author of the study group puts forward the business services model, and establishs the composite services implementation platform, which is called Business Service based Composite Service Execution Platform (BCSEP). Based on business services model and BCSEP, in order to better meet the dynamic needs of users, this thesis puts forward The Input and Output Interaction Services which enables users to interact with the system and dynamically affect the executing process of business services.This article study the Input and Output Interaction Handling Mechanism in BCSEP.In the process of the Input and Output Interaction Handling, in accordance with I/O interaction of different tasks performed by the I/O interaction requirements of the classification, this thesis gives the denotation of the I/O interaction needs. In order to identify I/O interaction requirements, this thesis establishs different rules with different requirements, giving automatic recognition algorithms of I/O interaction requirements. By analysising the match connections of parameters between trigger events and results events in business processes, automatic recognizing I/O interaction requirements. According to the different needs of I/O Interaction, this thesis classifies the I/O interaction services so that different types of I/O interaction services can meet different types of I/O Interaction requirements. This thesis then establishs the model of I/O interaction services, and creates I/O interaction services with I/O interaction requirements. this thesis gives the algorithms of creating I/O interaction services, transforming the input and output information of I/O interaction requirements into the input and output information of I/O interaction services.After introduced the I/O interaction services, business processes are re-arranged through establishing the match connection of trigger events and results events between business services and I/O interaction services, making the I/O interaction services joint into new business process. In the process of executing the new business services, both I/O interaction services and business services need to be executed. So this thesis gives a new framework for the implementation of business process and the implementation algorithms of new business services, described in detail the business processes of implementation.Finally, this thesis gives the I/O interaction design and the realization of the I/O interaction processor, and validates the feasibility and effectiveness of the method proposed by this thesis.
