PPT-Third Normal Form And Database Design

1 Are you sick of this slide yet Good relational database design is about optimizing how the data is STORED not how it is DISPLAYED Most tables you have seenin books in lectures on the webwere probably optimized for display not for storage. Also formal definitions of insertion anomaly and deletion anomaly are presented It is shown that a schema is in DKNF if and only if it has no insertion or deletion anomalies Unlike previously defined normal forms DKNF is not defined in terms of trad 1 Second Normal Form 32 Third Normal Form 33 Functional Dependencies 4 FOURTH AND FIFTH NORMAL FORMS 41 Fourth Normal Form 411 Independence 412 Multivalued Dependencies 42 Fifth Normal Form 5 UNAVOI ABL E RE DUNDA NCIES 6 INTERRECORD REDUNDA NCY 7 CO Basic SQL.
