This way the data in the table is tree structured. Also A single manufacturer has all mode of vehicles. I'm in my way to design this DB for use in PgSQL. But for a vast data, data retrieval is a very costly task (Joining all tables).
Can any one guide me of this design, on how the structure looks like. Hard about Inheritance feature of pgSQL. But not aware of how implementation goes.
Thanks in advance.
