Due largely to the effects of Bill Inmon, data warehouse systems have become a popular way to store information. Many companies have built them, now they need to learn how to manage them. In this book Inmon (the "father of data warehouse"), J.D. Welch and Katherine Glassy show database administrators and managers how to keep data warehouses running smoothly after they are built. Having essentially created the data warehouse system, there is no one more qualified than Inmon to demonstrate how to manage it. Here they cover all of the essential topics necessary for managing a data warehouse, including: monitoring operations and performance, administering data and tools, and mangaging change, growth and security.
