This topic is an overview of the features that can
be implemented through the sample catalog during the ETL process.
Delta load
The delta load process extracts only that data which has changed
since the last time a build was run. The delta load process is used for extracting
data for the operational data store of IBM Rational Insight
data warehouse.
This topic is an overview of the delta load implementation.
Reuse of ETL jobs
If the product data sources have similar structure, you can reuse
the same extract, transform, and load (ETL) job for all the data sources.
Inclusion of external data
At times, it might become necessary to create reports that
include data not present in the data sources defined for the extract,
transform, and load (ETL) process. This topic is an overview of the
process for including in reports such external data.
Data mastership
Businesses often use multiple tools to manage project information.
Data mastership is the mapping of these several disparate projects
to a single, common entity. The sample catalog defines a framework
for simplifying the ETL implementation for data mastership.
