Object Orientated Databases (P2)

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.

• 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

• 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)
