The following table highlights how TinyDB is different from MySQL and Oracle databases −

Comparison Basis MySQL Oracle TinyDB
Configurations Several Configurations Several Configurations Less Configurations, lightweight database
Complicated Yes Yes No, easy-to-use and hustle-free
Affordable No No Affordable than other databases
Manageable Big database, hence difficult to manage Big database, hence difficult to manage Small and manageable
