In this tutorial we will learn about the differences between Data Warehouse database and OLTP database and the objectives of a Data warehouse and Data flow. A data warehouse usually contains historical data that is derived from transaction data. I use this all the time when giving course on DW design and I get the students to produce a start schema based on these tables. A data warehouse is a database, data load and reporting system designed to aggregate data from multiple sources and present it in a manner which is easy to extract and report on. This tutorial will show you how you can document your existing data warehouse and share this documentation within your organization.
