Chapter 3 Relational Data Model And Normalization Pdf Relational Unit 3 part 1 normalization free download as pdf file (.pdf), text file (.txt) or view presentation slides online. the document discusses database normalization and issues with bad database design such as redundancy, anomalies, and memory wastage. What is normalization? normalization is the process of organizing the data in the database. normalization is used to minimize the redundancy from a relation or set of relations. it is also used to eliminate undesirable characteristics like insertion, update, and deletion anomalies.
