# Catalog Object (ADO MD)
Contains multidimensional schema information (that is, cubes and underlying dimensions, hierarchies, levels, and members) specific to a multidimensional data provider (MDP).  
  
## Remarks  
 With the collections and properties of a **Catalog** object, you can do the following:  
  
-   Open the catalog by setting the [ActiveConnection](../../../ado/reference/ado-md-api/activeconnection-property-ado-md.md) property to a standard ADO [Connection](../../../ado/reference/ado-api/connection-object-ado.md) object or to a valid connection string.  
  
-   Identify the **Catalog** with the [Name](../../../ado/reference/ado-md-api/name-property-ado-md.md) property.  
  
-   Iterate through the cubes in a catalog using the [CubeDefs](../../../ado/reference/ado-md-api/cubedefs-collection-ado-md.md) collection.  
  
 This section contains the following topic.
