Multiple account-types?

I'm currently using Symfony2 and doctrine. and I'm working on a "create-account" page. There will be 2 different kinds of accounts avaliable on the page, one for normal-usersand one for companies.

I've got an entity (table) called Account this table contains the username, passwordand saltcolumns.

If a company logs in I want to have the company information from a company-table and if a normal-userlogs in I want the information from the user-table.

I've been thinking about having a column named usertype which tells me what type it is, then if the usertype is a company retrieve the company-information-entity and if it's a userretrieve the user-information-entity (corresponding to the id of the account).

Is this a good way to solve this problem? or should I have 2 different tables? AccountUser and AccountCompany?

If you have many columns in Company table that don't exist in the User table and vice versa the best way to solve your problem is to use class-table inheritance which will create three tables: Account, User, Company. User and Company must be subclasses of Account entity.

According to link above you should have code like this:

namespace MyProject\Model;

/**
 * @Entity
 * @InheritanceType("JOINED")
 * @DiscriminatorColumn(name="usertype", type="string")
 * @DiscriminatorMap({"user" = "User", "company" = "Company"})
 */
class Account
{
    // ...
}

/** @Entity */
class User extends Account
{
    // ...
}

/** @Entity */
class Company extends Account
{
    // ...
}
