Data tables are frequently
used to define data stores. They can be used to define data stores,
summary data, a join, or a table that holds information that does
not conform to any other data storage type. A detail, or base, table
is any data table defined in the SAS metadata that contains the measures
and levels for a cube. The detail table consists of unsummarized data
that must include one column for each level and one numeric analysis
column for each set of measures that will be generated. There are
different types of data tables that can be used to build a SAS OLAP
cube. You can use the following tables to construct SAS OLAP cubes:
-
detail tables (base tables)
-
star schemas (a fact table and
associated dimension tables)
-
summary tables (NWAY data set)
-
-

SAS Intelligence Platform: Data
Administration Gujide for more information about managing
data table sources.
