Data architecture is a blueprint for how data is stored and flows across the enterprise over its life cycle. This sounds pretty simple. However, it is more intricate than it sounds. The focus of data architecture goes beyond individual systems to understand how data flows across systems; it goes beyond individual data stores to understand where the data is created, where it is maintained, how it is shared, and how it is changed across data stores. The focus of data architecture is also not on the hardware infrastructure, but rather on how the infrastructure network works to deliver trusted information.
