Currently I have the following database design

A user is either a person or a business entity. How do I extend this database design so that under a single business account, a business can allow for multi user access?

Example a business might want to give access their control panel access to an accountant, a developer, etc… A developer should only be able to view and manage applications while an accountant can view / download transactions etc…

USER
Id
Name
Username
Password
...




PERSONAL_INFO
UserId (PK-FK)
FirstName
MiddleName
LastName
....


BUSINESS_INFO
UserId (PK-FK)
BusinessName
....

Would this do it?

USER_ACCESS?
Id
BusinessUserId 
GrantedUserId

USER_PERMISSION
Id
UserAccessId
PermissionId

PERMISSION
Id
Name
Share

    i think, it’s better to add the entity BUSINESS_INFO and the attribute BusinessInfoId (foreign key to BUSINESS_INFO table) to USER table. The BUSINESS_GROUP table will have the primary key BusinessInfoId (of int type, e.g.)

    USER
UserId
BusinessInfoId (FK)
Name
Username
Password
FirstName
MiddleName
LastName
...

BUSINESS_INFO
BusinessInfoId (PK)
BusinessName
....

    notice, PERSONAL_INFO table is redundant. its fields must be normalized in USER table
