All tables support the IClass interface.
The CLSID property returns the globally unique identifier for the software component (COM coclass) representing the row objects stored and handed out by this table. Examples of the value of this property include the CLSIDs representing esriGeoDatabase.Row, esriGeoDatabase.Object, esriGeoDatabase.Feature, and esriGeoDatabase.AttributedRelationship.
The EXTCLSID property returns the globally unique identifier for the software component (COM coclass) representing the class extension associated with this Table. Class extensions are a mechanism whereby a developer can associate additional class level methods with an ObjectClass in the database.
The CLSID and EXTCLSID and other similar properties for a Table are stored in the geodatabase as part of the data dictionary information for the database. These properties link the behavior of the class (as implemented by software components in a DLL) with the data in the table.
The Extension property returns an interface on the ClassExtension associated with this Table.
The HasOID property may be used to test if this table has an Object ID column. Tables representing object classes and attributed relationship classes in a geodatabase will have an Object ID column whose values are unique and are assigned by the geodatabase as new objects and attributed relationships are created. The “Register With Geodatabase” command available on the context menu of a table in ArcCatalog can be used to register a pre-existing table in an RDBMS as an object class, this process will add an Object ID column to the table if needed.
The IClass interface also contains methods (inherited by ITable) to manage the collection of fields and indexes for a Table.
