What is the database design process used to increase integrity and reduce redundancy of data?

• Relational Design
• Data Constraints
• Error Handling
• Normalization

EXPLANATION

This process is used to create the Entity Relationship Diagrams necessary to design a database. Each level of normalization is a new "normal form". Typically databases use 3NF or 4NF.
The higher the normal form the more relational your database will be.
