A coherent software environment simplifies maintenance - and using the same terminology facilitates communication and learning within the IT department.

Having a mixed and complex software environment could put strain on the IT department. Applications and databases needs to be somehow cataloged in case of system failure. While mapping applications to databases using a unified terminology might seem to be a good idea from the start, but when it comes to generating a data model of interconnections based on terminology - confusion will arise. This confusion could lead to misinterpretations, which in turn could lead to incidents.
