Many to Many relationship in Dimension Modelling - Part 1


Some times business poses questions that are fundamentally flawed. However, the beauty of dimension modelling is, most times it doesn't allow you to build wrong logic. A typical example is many-to-many relationship between levels.


Question for this series: Consider a company where a product where belongs to one or more Product Groups, and a Product Group can have one or more Products. How will you represent that in a dimension model or cube?


So, in this series we will discuss various options, their pros and cons, the fundamental flaw in this question and something I call as 'intelligent modelling'.


I hope I will get a good audience for this series, and useful comments.
