○ They include
• Investment , Resource, Timesheet Information
○ Data updated in real time (Live Tables)
● Time Slice Tables
○ Houses summarized data by Daily, Weekly, Bi-Weekly, Monthly, Bi-Monthly, Quarterly,
Semi-Annually, Yearly views
○ These tables are populated via a job process – Time Slice
○ Time Slices are critical to define how much data is summarized
● DataMart Tables
○ Provides Summary and Rollup Data
○ DataMart is populated via several job processes – Rate Matrix Extraction, DataMart
Extraction and Datamart Rollup

Time Slice Tables
● Time and Hour metrics are stored as blobs and are unreadable
in the day to day production tables.
● Time Slice tables open a window to this data for viewing.
● These views allow Clarity to group data into Weeks, Months,
Quarters etc…
● This grouping allows for more efficient queries.
● Need to tell it what slice you are going after.
● Keep your daily slices to a minimum.
● Resetting Slices.

Description
Primary key constraints need to be named explicitly as they
control the name of the primary key index (which is
automatically created)
Foreign key constraints need to be named explicitly (“alter
table XYZ add XYZ_FK1 foreign key …”)
i.e. CK1 or CK2
i.e. U1
i.e. N1 or N2
i.e. S1 or S2. S1 is used for primary key sequences only, i.e.
CMN_LOOKUPS_S1.
i.e. TRG1 or TRG2, T1 or T2

● INV_HIERARCHIES_FLAT
○ This denormalized table stores data based on INV_HIERARCHIES. The flattened
table contains parent_id and child_id entries for all descendants of a given
investment parent_id that has a hierarchy. The link_source_id contains the ID
of the immediate parent of the child. This table enables rapid retrieval of all
descendants within a hierarchy. By examining the link_source_id, the original
hierarchical order can also be retrieved.
● Can return Program/Master/Sub relationships.
