Data Warehousing, first step in Data Mining.

Data Warehousing is one of the important aspects in data mining, without a data warehouse, you will get lost with all your data, Imagine thousands of excel files that you will be merging without any primary key, this will really make you feel lost, Always structure your data in such a way that they can be linked together like a star schema or snow flake schema, make sure that your data lies in one platform, it can be in MS SQL Server, Oracle or a large scale database server.

Once all of these are in place, then that is the time you will be able to do data mining, up to the last minute detail. This type of process is also helpful in creating your Digital Dashboard.
