INTRODUCTION AND TERMINOLOGY

WHAT IS DATA WAREHOUSE?

Loosely speaking, a data warehouse refers to a database that is maintained separately from an organization’s operational database

Officially speaking: “A data warehouse is a subject-oriented,

integrated, time-variant, and nonvolatile

collection of data in support of

management’s decision-making process.”—

William. H. Inmon

Alternative names: knowledge discovery/extraction,information harvesting, business intelligenceIn fact, data mining is a step of the more generalprocessof knowledge discovery in databases

APPLYING DATA WAREHOUSING IDEAS TO PROJECT DATA

•Pulling data together•Using data correctly

Pulling data together

Data may be pulled in and manipulated at any point along the way; the programmer may mix together the program logic that acquires the data with the program logic that generates the desired results from it in any way that seems easy and efficient.

Using data correctly

Data cleaning goes a long way toward ensuring that data will be used correctly, but a well-designed data warehouse goes beyond this. A data warehouse uses additional variables and documents to describe the meaning of data elements,values, and records. This additional data is called metadata because it describes the data being used.The data warehouse approach: Use metadata to describe the meaning and source of data.
