FdoProvider Class
A base class for connecting to and management of FDO data stores. Data store is a repository of an integrated set of objects. The objects in a data store are modeled either by classes or feature classes defined within one or more schemas. Some data stores can represent data in only one schema, while other data stores can represent data in many schemas.

Public methodDeleteObjectT
Public methodDestroySpatialContext
Destroys default FeatureSchema spatial context, if such operation is supported by present Provider.
Public methodDestroySpatialContext(String)
Destroys named FeatureSchema spatial context, if such operation is supported by present Provider.
Public methodDispose
Disposes FdoProvider object. Automatically closes and disposes any opened connection established via OpenConnection(FdfResultCollection) method.
Protected methodDispose(Boolean)
Releases the unmanaged resources used by the FdoProvider and optionally releases the managed resources
Public methodDisposeConnection
Closes and disposes an IConnection connection object previously opened using OpenConnection(FdfResultCollection) method.

Remarks
A feature class is a schema element that describes a type of real-world object. It includes a class name and property definitions, including zero or more geometric properties. It describes the type of data that would be included in object instances of that type.
