This document provides an overview of a business intelligence (BI) system architecture. It includes a product database using Attunity for change data capture fed into a Teradata data warehouse. An ETL system extracts and transforms the data from the warehouse for analysis in Tableau, a BI reporting tool. Centralized logging of the database, applications, and web console are stored in a separate logging database.
