warehousing data1st then data mining
If you are asking about histroy, data mining came first, data mining has been around for a long time but under different names, in computer science it all started with the term Artificial Intelligence and then Machien Learning and now Data Mining is considered part of Machine Learning.
On the other hand, if what you meant to ask is "What comes first?', then I would say that Data Warehouse is not related to Data Mining, although some people prefer that a data warehouse be available to store the data before applying data mining on it.
One needs to be careful, Business Intelliegence (BI) and Analytics is different from Data Mining, some people use the term BI to refer to a complete solution that also includes data mining.
Data Mining can be applied on any kind of data from any source, not neccessarily be it in a data warehouse.
First, data warehousing to prepare selected and valuable data for data minning
