Welcome to this second paper in an ongoing series regarding common data modeling mistakes and their impact. This series of papers presumes that poor database design: ... Analysts unsure of concepts such as cardinality, optionality, and normalization. Information systems staff unsure as to the actual business rules and requirements.

This week also includes concepts of data normalization and understanding the different normal forms and how to apply in business applications. In Week Four you will take the third step in data modeling and transform your logical data model into a physical implementation using the Oracle® Express® database management system.

Define data normalization. Explain why data normalization is important. Explain how normalization helps reduce redundancy and anomalies. Solve data anomalies by transforming data from one normal form to the next; to the third normal form. Apply normalization with data modeling to produce good database design. Lab Goals. Our lab goals are to:

Normalization. Semantic data modeling. Normalization starts with the assumption that everything is initially stored in one large table. A set of rules is followed to decompose that initial table into a set of normalized tables. The objective is to produce a set of tables in third-normal form (3NF) because such tables are free of update, insert ...

(1) Normalization: Assumption is that all data is stored in one large table! Then a set of (normalization) rules are applied which will decompose the table into a set of normalized tables. (2) Another approach is to use semantic . data modeling (E-R & REA) to design a well-structured RDB. This has certain advantages over normalization.
