Unit 7: Object-Oriented and Object-Relational Databases
As object-oriented programming gained popularity in the 1990s, object-oriented database management systems that incorporated all of the principles of object-oriented design began to emerge. A short time later, a hybrid approach known as object-relational databases was adopted. In this unit, you will first learn about object-oriented databases and then object-relational extensions to relational database management systems.
Completing this unit should take you approximately 12 hours.
