Serialization and Alternatives
When is it appropriate to use serialization?
What are the alternatives to serialization?
Serialization
An easy way to save and restore objects in between program sessions
Useful in many projects where persistency is necessary, but not a key topic
Requires only little programming
Custom programmed file IO
Full control of object IO
May require a lot of programming
Objects in Relational Databases
Impedance mismatch
: "Circular objects in retangular boxes"
Useful when the program handles large amounts of data
Useful if the data is accessed simultaneous from several programs
Not a topic in this course
