Research And Implementation Of Personal Security Trading System Based On SOA

SOA(Service-Oriented Architecture) has become the hot research in IT domain. Comparing to legal architecture, SOA, as a architecture model, has such properties: based on standards, loose-coupled, service-shared and coarse-grained etc. By Applying SOA, we will reuse legacy assets, improve development's efficiency, decrease cost, increase reusability. Nowaday, Web Services is the best implementation of SOA. Web Services possesses the advantages: independent of any platforms and languages, good interoperability, support by broad manufacturers, lower cost, based-on open standard and availability for incremented development.How to construct an excellent trading system always is a hotspot in security stock traders. A well-designed trading system, establishing a set definitely rules for every phrase in investment decision, helping traders effectively control his psychology and manage the risk, guaranteeing traders having a long and stable profit in security market.After studying and researching current trading systems and security operating systems, we introduce a new architecture: Architecture of Security Information Service Platform Based on SOA(SISP-SOA). Architecture of SISP-SOA, as a loose-coupled architecture, will reuse current legacy system effectively. Security information platform, with applying the architecture of SISP-SOA, will effectively organize structured and half-structured information in internet, traders can access information briefly, efficiently, swiftly, accurately. With Architecture of SISP-SOA, developers will use web services components to construct information software, that decreases complexity of development and maintenance, improving efficiency in development.Framework of Personal Security Trading System (PSTS-SOA) is one of application of architecture of SISP-SOA. Software with framework of PSTS-SOA, with openness, extensibility, independence of platform, integration, is convenient for personal traders to construct, valuate, improve trading systems by combining web services components.An software, based on PSTS-SOA Framework, gives an instance for developers and traders.
