A relational DBMS is designed in such a way that the data in the relation is integrated while also remaining non-redundant. This is achieved through the normalization process, which breaks down the data into smaller, more manageable tables and eliminates redundant information. The relational DBMS can automate the process of extracting data from multiple tables and presenting it in a way that appears integrated, but the underlying data remains non-redundant.
