Data modeling is the process of representing data in a form that is easy for business users to understand and find answers to their questions. Data modeling requires a centralized approach to ensure consistent enterprise metrics as well as a self-service approach for business users to blend data...
The ones that query it aren't a problem. If they don't ask for the new column, they won't get it and won't realize that the table has been changed (this is one of the big selling features of the RDBMS). But the scripts that update the table will all need to be changed. If ...
strong focus on data quality is also a must. In both cases, though, IT and data management teams can't go it alone. Business executives and users must be involved to make sure their data needs are met and data quality problems aren't perpetuated. The same applies to data modeling ...
