Fidelity National Financial started the process of creating a data map, or a consolidated system that tracks the contents of multiple databases, over two years ago. Bruce Phillips says the data mapping process is arduous and requires commitment of both time and resources. Phillips: “If you don’t have multiple constituents, don’t try it. Unless you have a lot of uses for it, it’s just too hard to do it for it” The end benefit is that the company has a much firmer grasp of their systems and can quickly respond to data requests.”]
