The MDStore interface supports the following collections.

Collection	Description
Commands	The collection of user-defined commands or sequence of commands
CustomProperties	The collection of user-defined properties
DataSources	The collection of objects specifying a data provider
Dimensions	The collection that holds the dimension definitions for an object
MDStores	The collection that holds MDStore objects
Measures	The collection that holds the measures
MiningModels	The collection of data mining models contained within a database
Roles	The collection that holds the user role definitions for a database

The following table shows the class types of the objects that each collection can contain.

Collection	Class type of contained objects
Commands	clsCubeCommand, clsDatabaseCommand
CustomProperties	Property
DataSources	clsDataSource
Dimensions	clsAggregationDimension, clsCubeDimension, clsDatabaseDimension, clsPartitionDimension
MDStores	clsAggregation, clsCube, clsDatabase, clsPartition
Measures	clsAggregationMeasure, clsCubeMeasure, clsPartitionMeasure
MiningModels	clsMiningModel
Roles	clsCubeRole, clsDatabaseRole, clsMiningModelRole

Access Cross-Reference

The following table shows whether a collection is read/write (R/W), read-only (R), or not applicable (n/a) for each of the MDStore objects.

Collection	clsDatabase	clsCube	clsPartition	clsAggregation
Commands	R/W	R/W	n/a	n/a
Custom Properties	R/W	R/W	R/W	R/W
DataSources	R/W	R/W*	R/W	n/a
Dimensions	R/W	R/W	R	R
MDStores	R/W	R/W	R/W	R
Measures	n/a	R/W	R	R
MiningModels	R/W	n/a	n/a	n/a
Roles	R/W	R/W	n/a	n/a

*This property is not applicable (n/a) for virtual cubes (that is, those of SubClassType sbclsVirtual).
