This particular edition of Jack’s Guides looks at the Data Retrieval, SQL and Data Warehouses.

The term “Data Warehouse” is used frequently in IT circles, sometimes correctly sometimes not, and is often a mystery to people who have not been initiated.

We help you to understand what a data warehouse really is, how it is different from a relational data base, and when and why you would use one.

In order to get to this understanding we take a look at what a relational data base is, and how it works. We then look at why the relational data base is often supplemented by a data warehouse for data reporting and data mining.

We explore the different models of data base and explain what is meant by terms such as normalisation, first normal form, dimensional models, star schemas etc.

We look at the components, hardware and software, which make up a data warehouse, how data can be loaded into one, and the various types of reporting that are used.

Finally we list some of the more well-known tools and products of the data warehousing world.

This ebook will give you an overall understanding of BI as it is used in the real world and will help you to:

• Become knowledgeable about a product that is fast becoming a "must have" in many IT jobs
