Creating an Analytic Workspace From Relational Tables, 5 of 6
You can discover the names of objects by browsing through the metadata catalogs, which are variables named ___CWM.
object
.CAT
in the analytic workspace. Note that three underscores prefix the name.
Table 9-1 lists the names of the basic catalogs. To see a full listing of the catalogs, issue a LISTNAMES VARIABLE
command.

The Catalog catalog provides detailed information about each measure folder. Each folder or catalog is represented by a member of the ___cwm.cat.ent
dimension. The following example shows the entries for the xademo_cat
catalog.
report ___cwm.cat.cat -----___CWM.CAT.CAT------ -----___CWM.CAT.ENT------ ___CWM.CAT.PRP 95 -------------------- ------------------------- CATALOG_NAME XADEMO_CAT PARENT_CATALOG_ID NA DESCRIPTION XADEMO CWM Business Area
The Cube catalog provides detailed information about each cube. Each cube in the xademo
schema is represented by a member of the ___cwm.cb.ent
dimension. The following example shows the catalog entries for analytic_cube
. The Description field shows that this cube contains five measures (sales
, quota
, cost
, units
, and promo
), which are dimensioned by time
, channel
, product
, and geography
.

The Measure catalog provides detailed information about measures. Each measure in the xademo
schema is represented by a member of the ___cwm.meas.ent
dimension.
The following example lists the catalog entries for the f.sales
measure. They show that the data from the sales
column of the xademo_analytic_facts
table is mapped to a workspace variable named __meas5
. Note that two underscores begin the name.

The Dimension catalog provides detailed information about dimensions. Each dimension in the xademo
schema is represented by a member of the ___cwm.dim.ent
dimension. The following example lists the catalog entries for the geography
measure. They show that the workspace geography
dimension is named __dim3
, and the workspace objects that support the geography hierarchies have an A3.
prefix.

The Hierarchy catalog provides detailed information about dimension hierarchies. Each hierarchy of each dimension in the xademo
schema is represented by a member of the ___cwm.hier.ent
dimension. The following example lists the catalog entries for the two geography
hierarchies, standard
and consolidated
.
report ___cwm.hier.cat ------------------___CWM.HIER.CAT------------------ ------------------___CWM.HIER.ENT------------------ ___CWM.HIER.PRP 4 5 ------------------ ------------------------- ------------------------- OWNER XADEMO XADEMO DIMENSION_NAME GEOGRAPHY GEOGRAPHY HIERARCHY_NAME STANDARD CONSOLIDATED DISPLAY_NAME Standard Consolidated DESCRIPTION Standard GEOGRAPHY Executive Consolidated hierarchy GEOGRAPHY hierarchy DIMID 6 9 XADEMO GEOGRAPHY 6 9 XADEMO GEOGRAPHY HIERID 6 9 8 XADEMO GEOGRAPHY 6 9 12 XADEMO GEOGRAPHY STANDARD CONSOLIDATED
The Level catalog provides detailed information about dimension levels. Each level of each dimension hierarchy is represented by a member of the ___cwm.lvl.ent
dimension. The following example lists the catalog entries for the two of the four geography
levels. From this catalog, you can learn that geography
members at the city level are stored in a workspace dimension named __rdblvldim9
, and geography
members at the country level are stored in a workspace dimension named __rdblvldim10
.

The Level Attribute catalog provides detailed information about level attributes. Each level attribute for each dimension level is represented by a member of the ___cwm.lvla.ent
dimension. This dimension can be quite large, so you might want to use a command like the following to limit your view to the level attributes for a single dimension:
limit ___cwm.lvla.ent to (___cwm.lvla.cat(- ___cwm.lvla.prp, 'DIMENSION_NAME') eq 'GEOGRAPHY')
The following example lists the catalog entries for one of the geography level attributes. From this catalog, you can learn that the long names for cities are stored in a variable named __rdbattrvar19.
report ___cwm.lvla.cat ----------___CWM.LVLA.CAT---------- ----------___CWM.LVLA.ENT---------- ___CWM.LVLA.PRP 19 ------------------------- ----------------------------------- OWNER XADEMO DIMENSION_NAME GEOGRAPHY ATTRIBUTE_NAME GEOG_STD_CITY_LLABEL DISPLAY_NAME Long City Name(s) DESCRIPTION Long Labels for Cities values of the STANDARD GEOGRAPHY hierachy DETERMINED_BY_LEVEL_NAME L4 COLUMN_NAME GEOG_STD_CITY_LLABEL DATA_TYPE TEXT DIMID 6 9 XADEMO GEOGRAPHY LVLID 6 9 2 XADEMO GEOGRAPHY L4 LVLAID 6 9 2 20 XADEMO GEOGRAPHY L4 GEOG_STD_CITY_LLABEL RDBMS_ATTRVAR_NAME __RDBATTRVAR19
