ADVANTAGES:• Controlling Redundancy• Integrity can be enforced• Inconsistency can be avoided• Maintains privacy

DISADVANTAGES:• Complexity• Size• Performance• Cost

Hierarchical Structures

• Relationships between records form a hierarchy or treelike structure• Relationship is one-to-many

Network Structure• Many-to-many• Data element can be accessed by following one of several paths
