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.
