Data architecture
Data architecture is a sub-discipline of IT architecture that deals with fundamental structures and principles of data and information , their construction, use and further development. She practices a holistic view of the observed elements and can look at them in a “coarsened” model.
The term “data architecture”, also known as information architecture , is often equated with data modeling (see), but the focus is much broader.
Secondary disciplines
Further sub-disciplines of IT architecture are: technology architecture , application architecture , process architecture , IT security architecture .
Examples of sub-topics
According to Tiemeyer and Meier, the following focal points are mentioned as examples as the content of the data architecture:
- Directory of all data / information in the company
