A thorough database design process will undergo four distinct phases, as follows:•Conceptual: This is the “sketch” of the database that you will get from initial requirementsgathering and customer information. During this phase, you attempt to identify what theuser[r]
missing from the database. No role is more critical to any datacentric application than the role ofthe data modeler. User interfaces come and go, but data lasts for generations of application lan-guages, and today’s database schema errors will be cursed by p[r]

What is it that our customer produces? Why, it's automobiles of course! Wouldn't our customer want to track the company's performance in many ways? We are probably safe in assuming that we need to create a Total Vehicle dimension that allows us to look at the data by an i[r]

Smart keys are useful tools to communicate a lot of information to the user in a small package. However,all the bits of information that make up the smart key need to be identified, documented, and implemented in astraightforward manner. Optimum SQL code expects the data[r]
