In Information Technology, a disparate system or a disparate data system is a computer data processing system that was designed to operate as a fundamentally distinct [1] data processing system without exchanging data or interacting with other computer data processing systems. Legacy systems are examples of disparate data systems as are heterogeneous database data systems.

Overview[edit]

Each data system may be envisioned as being composed of a software layer or applications architecture, a data layer or data architecture, and a data processing environment layer or technical architecture. Any of these three layers may contribute to forming a disparate data system.
