Discussion focusses on workload where there are multiple systems that will feed a data warehouse.  A question came out as to how to tie the data sources together?  One aspect is the concept of mapping source information together using unique identifiers that can be created by a data modeller, or BA doing the data model in the staging environment where extraction and transformation occurs prior to loading data into the data warehouse.

Very engaging discussion around real world usage of connecting various sources using data warehouse concepts.

The afternoon session will focus more on activities where participants will create a model using case study data and applying this principle.
