DATA MAPPING

Please can someone help me with a sample document of data mapping(dimensions and facts),
The task I am to do is for an existing Data warehouse, I am develop something like a data dictionary of the dimensions and fact in terms of how their attributes are derived, I have looked online and have seen some basic table type. I am just checking if there is a better standard template.

Thank you

Which platform are you using?

If it is Microsoft-based, Pragmatic Works has a product named DOCxPRESS that does a good job.

Thanks for the reply, its microsoft based, I was looking for a free tool, checked out docxpress
