Subj:   Re: Why not use star schema

  A good 3NF schema modeled on how the business functions will most likely be independent of any source schema model; but all the more efficient to source if they actually matched. The reasons for a "star schema" are still valid for user (application) interpretation; whether or nor it is logically or physically implemented.  

Thanks. When would you choose to implement a source-independent 3NF vs. a source-independent dimensional model?

In particular if your goals are:

* Make the model as simple as possible for the end user to understand.

* Make the model as adaptable as possible to end user tools.

* Accomodate as much as possible differences and changes in source systems.
