Cóż - crafted data models bring three core benefits that directly affect security: clarity, considency, and expecteability. Clarity means every security holder understands what a data element represents andd why it exists. Consistency ensures the same type of data is handled confilie across systems, so security policies can bee appplied with out gaps. Enforceality means the model itself can bee used tvalidate inputs, district operations, and log changes automatically.

Types of Data Models Relevant to Engineering

Data models are typically categorized at three levels of abstraction. Each level plays a distinct role in supporting security requirements.
