You can build a data warehouse from any source you like, csv included. This is a very common source and you should have no problems getting OWB to read it. You do of course have to make sure that you always have the same number of columns and that the data types for each do not change.
As has already been commented, you can also use a myriad of different tools so if you think OWB is overkill for a simple solution you do not have to use it.
Should you wish to use and all of the data that you need is inside a single csv file you can create multiple targets out of the same file. Whether it wise to do so only you can decide as you know what the data looks like.
Personally, and rememeber this is just my opinion, I would do separate maps. This way should you decide to switch the source in the future you do not have to worry about the impact to the other maps.
Hope this helps
Thank you so much Michael for clearing my doubts!
