Armstrong's Axioms

Armstrong's Axioms are a set of rules used in database theory to infer relationships between data. They help determine how different pieces of information are connected. The three main axioms are: 1. **Reflexivity**: If a set of data includes certain attributes, it also implicitly includes any subset of those attributes. 2. **Augmentation**: If one set of attributes determines another, adding more attributes doesn't change this relationship. 3. **Transitivity**: If one set of attributes determines a second, and that second set determines a third, then the first set determines the third as well. These principles are crucial for understanding dependencies in databases.
