Collections (DSO)

Note

  This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.

Collections used in Decision Support Objects (DSO) generally operate the way standard Microsoft® Visual Basic® collections do. However, there are several differences specific to DSO. DSO collections contain methods and properties that have implementations specifically designed for the DSO object model.

Unlike typical Visual Basic collections, DSO collections can contain only objects of the same type. For example, a Dimensions collection can contain only objects of the object classes that apply to dimensions, such as ClassType clsDatabaseDimension, clsCubeDimension, clsPartitionDimension, and clsAggregationDimension. The parent object of a collection determines the specific ClassType property value for the collection. For example, a Dimensions collection whose parent is of ClassType clsDatabase can contain only objects of ClassType clsDatabaseDimension.

A collection is considered to be static for an object if the range of acceptable objects in the collection is restricted. For example, the Roles collection for an object of ClassType clsCube is a static collection because it can only contain role objects that are defined for the cube's parent database object.

The following table lists the collections used in the DSO object model. With the exception of CustomProperties, all collections implement the methods and properties supported by the clsCollection object. For more information about the implemented properties and methods for clsCollection objects, see clsCollection.

Collection	Contains objects of ClassType
Commands	clsCubeCommand, clsDatabaseCommand
Columns	Column objects that make up a mining model's structure (ClassType does not apply)
CustomProperties	Property Object (ClassType does not apply)
DataSources	clsDataSource
Dimensions	clsAggregationDimension, clsCubeDimension, clsDatabaseDimension, clsPartitionDimension
Levels	clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel
MDStores	clsAggregation, clsCube, clsDatabase, clsPartition
Measures	clsAggregationMeasure, clsCubeMeasure, clsPartitionMeasure
MemberProperties	clsMemberProperty
MiningModels	clsMiningModel
Roles	clsCubeRole, clsDatabaseRole
