A Study on a Framework for Persistence Layer Supportable Web Services in Distributed Environments

Abstract

The web service was proposed as a standard to assemble service modules without any relation where they exist in distributed environments. The standard web service is declared with XML based language about registration, searching, orchestration and execution, which will be used to represent domain data model and process model. Each model can be mapped between data object and execution object but the mapping process have no standard so it can cause higher coupling between logics for processing domain objects and for business. Therefore, a web service framework should provide a domain model to reduce coupling and it must support features for registration, searching, orchestration and execution which are compatible with the standards. We propose a framework for persistenc layer supportable web services in distributed environments. Proposed framework is implemented for service registry, orchestration engine, execution engine, and a meta model for various domain. In service registration and searching, it shows high performance because it uses hashing based searching. And it shows higher performance than other ORMs such as the Hibernate and iBatis on the MS-SQL which is general DBMS in factor of domain objects’ creation, modification and removal.
