Object Orientated Databases (P2)

Question 1

What is an ODD?

Answer 1

Object-orientated databases store data as objects and do not have any tables or use SQL. Objects contain both data and functions that can be performed on the data.

Question 2

3 advantages of OOD

Answer 2

• Can store a larger number of data types
• Better performance when there are complex data structures and relationships
• Reusability of functions because each object is defined by a class, and classes can take functionality from other classes through a process called inheritance

Question 3

3 disadvantages of OOD

Answer 3

• Lower efficiency when data structures and relationships are simple
• More user tools exist for relational databases
• OODs are less secure (you cannot set user access rights)
