Video Description

In this section we have a look at the various database models: - Hierarchical - this database structure is much like an org chart and is tree-like in fashion. Examples of this model are the DNS and Active Directory. - Distributed - in this model, there is no single server where the database resides. Instead, it is distributed across numerous locations. Again, DNS is an example. - Object-oriented - this model uses the concept of objects as opposed to just treating everything as text. As a result, it's more complex. Characteristics of the OO model are reusability and being modular in nature. - Relational - this model is based on tables that are related via fields that they hold in common. Examples of relational databases are MySQL and Oracle. We'll spend most of our time here!
