I am am developing a recruitment application for storing records of people who come for an interview. So I have two models - Applicant & Employee which seem like one in OO sense. i.e. Employee was earlier an applicant. Therefore I am planning to create a Single table inheritance like:
Applicant < Person
Employee < Person
All the fields of Applicant are there in Employee. Employee has several other fields that are not in Applicant.
Am I correct with this plan. I have another similar scenario to deal with - prospects & clients.
Update: As I am working more and more with STI, I am starting to dislike it.
