Schema

Schema is a logical description of each piece of data in the database and its relationship with other data elements. It does not identify the actual value of the data.


From the aspect of Psychology, Schema is a mental model or framework within which new experiences are digested.

This term is extensively used by Jean Piaget in his descriptions of the way in which children make sense of the world at different stages of development.
