Terminologies
This section describes the terminologies used for data maps included in the document.
<Table Name>
The Table Name indicates the name of the fact or the dimension in a star schema in the data warehouse.
Properties
The Properties table lists properties of the table independent of each field. The following properties are listed in the table:
Property
Value
Target Table
Name of the table in the target schema (data warehouse) into which data is loaded
Table Type
Fact or Dimension
SCD Type
Type 1: Existing records are updated directly. The nature of the dimension on how it handles changes made in the source system.
 
Type 2: Existing records are inactivated by putting the current date as the effective end date and new records are inserted with an effective start date as today’s date. The new record will have the start date as the current date and a high date.
Fact Type
Whether this is a snapshot or transactional fact table
 
Snapshot: Captures a snapshot view of the data as available in the source system during that period (monthly or weekly). Each snapshot's data is stored independently.
 
Accumulation: Data from the source system is accumulated periodically. Changes from source system will be merged with the existing data. Multiple copies of the same data will not be maintained.
Source System Driver Table
Name of the table in source database from which data is extracted
Stage Table
Name of the table in the staging schema (data warehouse) that can be used to query the data records generated by the ETL logic
Oracle Data Integrator Package
Name of the ODI package that needs be executed to extract data from the source application and populate a specific target table in the data warehouse
ETL View
Name of the view in the data warehouse that has the logic for retrieval and transformation of the source data
Materialized View
Names of the materialized views delivered with the product for a specific fact table
 
These materialized views are designed to support all of the OAS answers delivered with the product. Refreshing these materialized views will be taken care as part of the ETL processes.
Fields
The Fields table lists the individual properties of each field in the presentation table or the database table. The following fields are listed in those tables:
Property
Value
Source Field
