Contrast a network and hierarchical database model?
Expert
The hierarchical model is a top-down structure where each and every parent might have many children however each and every child can have only one parent. This model supports relationships one-to-one and one-to-many. The network model can be much more flexible than the hierarchical model because each and every parent can have multiple children however each and every child can also have many parents. This model supports relationships one-to-one, many-to-many, and one-to-many.
