Why user table has large no of columns ? Why don't we have different tables for specialized class like B2BCustomer , Employee etc ?

Why does hybris have data of all specialized types of users into user table only? What are the advantages of such a schema ?

    Read up on Table per hierarchy vs Table per class e.g.


    TPH = better performance but more redundant columns and no chance of data integrity rules in the db

    TPC = worse performance (more joins) especially with large hierarchies but no redundant columns and possibility of enforcing data integrity in database
