Hi Folks/Fellow Developers,
As I’ve seen lot many examples, articles over Single Table Inheritance, I decided to write my own. Thanks to the open source contributors. Their Articles/Examples helped me a lot writing this post.
As you might know about single table inheritance, let me quickly set the definition for it. Single-Table-Inheritance (STI) allows you to write/create sub-classes of a specific model. You can use a single table, add specific objects and extend the functionality/behavior of base model.
Current example explained:
My Current example is based on Mobile system. We have a single model called ‘Mobile’ and other models such as ‘Samsung’, ‘Apple’, ‘Nokia’ etc., that inherits the property of Mobile model. (Refer to the image for more help)
