What is Introduction to Relational Model about?

The document provides an overview of the relational model for databases including: - Relations consist of attributes (columns) and tuples (rows) that make up a table. Attributes have domains and can allow null values. - Relations schemas define the attributes of a relation. Relation instances are the current data values stored in a table. Relations are unordered sets of tuples. - Keys like candidate keys and primary keys uniquely identify tuples. Foreign keys enforce relationships between relations. -
