Aim: Apply the database Normalization techniques for designing relational database
tables to minimize duplication of information like 1NF, 2NF, 3NF, BCNF. Recommended Hardware / Software Requirements: Hardware Requirements: Intel Based desktop PC with minimum of 166 MHZ or faster
processor with at least 1GB RAM and 500 MB free disk space. MySQL 5.6.1
Prerequisites: Student must know about the Relational database(SQL)
Normalization is a process of converting a relation to be standard form by decomposition a
larger relation into smaller efficient relation that depicts a good database design. 1NF: A Relation scheme is said to be in 1NF if the attribute values in the relation are
atomic.i.e., Mutli –valued attributes are not permitted. 2NF: A Relation scheme is said to be in 2NF,iff and every Non-key attribute is fully
functionally dependent on primary Key. 3NF: A Relation scheme is said to be in 3NF,iff and does not have transitivity
dependencies. A Relation is said to be 3NF if every determinant is a key for each & every
functional dependency. BCNF: A Relation scheme is said to be BCNF if the following statements are true for eacg
FD P->Q in set F of FDs that holds for each FD. P->Q in set F of FD’s that holds over R. Here P is the subset of attributes of R & Q is a single attribute of R. xi) The given FD is a trival
xii) P is a super key.
