Abstract:The paper discussed a new type of model of software architecture used for oil/gas geophysical field, which surpassed traditional three-tier architecture, separated control engine from functional module logic in each tier, and included uniform software bus and application framework. The paper presented that the main body of model in geophysical software architecture consists from (central part's) interactive (UI user interface) tier, application tier, data tier as well as system service bus and application framework. These components of architecture are constructed on the platform of extended operational system of computer. The software architecture has four basic properties: layered structure, separating control engine from functional module, uniform service for system performance and framework-based application development of software. The model of software architecture presented in the paper is convenient for both application integration and data integration, and management of process developing software system, software maintenance and property rising, which is hopeful to be used for study and development exploration and development product line.
