**(PDF) Pattern classification using fuzzy relational calculus**

Relational Calculus Spring 2002 CSC 742: DBMS by Dr. Peng Ning 2 Relational Calculus: 1 Can define the information to be retrieved 4not any specific series of operations In contrast, relation algebra defines the sequence of operations. Closer than relational algebra to how users would formulate queries in terms of their information needs, rather than in terms of operations. Spring 2002 CSC 742... Relational Calculus. Relational calculus is a non-procedural query language. In the non-procedural query language, the user is concerned with the details of how to obtain the end results.
