AcMapFeatureService Class
Provides an abstraction layer for the storage and retrieval of feature data in a technology-independent way.
class AcMapFeatureService : public MgFeatureService;
Remarks
The API lets you determine what storage technologies are available and what capabilities they have. Access to the storage technology is modeled as a connection. For example, you can connect to a file and do simple insertions or connect to a relational database and do transaction-based operations.
