Data Type
String (maximum length 50 characters, exclusive of any plus signs)
Access
Access depends on the value of the ClassType property of the object.

clsCube |
R/W |
clsDatabase |

Aggregation prefixes are used to generate aggregation names, and they are used for table names in the relational database.
A fully expanded aggregation name has four parts:
<DatabasePrefix><CubePrefix><PartitionPrefix><AggregationID>
The first three parts of the name are provided by the user and make up the aggregation prefix; the fourth part of the name is a system-defined ID over which users have no control. The first two prefixes (DatabasePrefix and CubePrefix) are optional. CubePrefix is used only if PartitionPrefix begins with a plus sign (+), and DatabasePrefix is used only if CubePrefix begins with a plus sign. For example, if PartitionPrefix is +_Partition1, CubePrefix is +_1995, and DatabasePrefix is Sales, the aggregation prefix is Sales_1995_Partition1.
