Abstract: Domain-specific software is characterized with heterogeneous data and resources, complicated business processes and changing business requirements from users. It is of practical significance and great value to find out a technique for integrating these software which may be developed by different people using different languages and technologies , and provides very different functionalities. Considering the characteristics of oil-drilling engineering, a goal-tree based domain-specific modeling technique and a SCA based platform independent modeling technique were suggested,which SOA and MDA arc used for reference to. Finally, a real case, Simulation System of Oil-Drilling Engineering,shows the modeling techniques are practical to integrate domain-specific software and can meet the requirements to flexihle extension and confi}nration of hnsiness modules.
