It is called a data warehouse. (and&#x2F;or Business Intelligence) You can have disparate systems that each create their own data... and each datum comes from the system that &quot;owns&quot; that data. But it gets aggregated to a central location, which owns none of it, but pulls it together for reporting and analysis.<p>There are comments here giving some examples of products intended to help with this, but this is one of those area where the concepts are easy, but execution is challenging. I&#x27;d recommend looking less at products, and more at theory to decide how you want to approach it... and then go back and see if any of the products match your decisions.
