Implementation of Embedded File System Based on SOA with Three-tier Architecture
Yaoli Wang · Journal of Taiyuan University of Technology · 2011
The embedded file system was implemented based on SOA architecture.According to requirement-semantics-service three-layer architecture,the file system design and overall program was completed.The requirement layer built domain ontology model of files business systems using UML modeling,Ontology modeling tool Protege and Reasoning plug-in pellet.The semantic layer established a semantic feature tree and described the form of semantic feature tree with the language of OWL/RDF.The corresponding atomic business was found based on the processing of business use cases,use case scenarios,business steps analysis.The system requirements were mapped according to the atomic business and the system model was built,then the corresponding set of atomic components was obtained.The sequence of scene steps was described as the combination of a series of atomic components using the formal semantics.
