Development of a database for a rating system

The application processes users and objects, users evaluate objects with three functions (one speed for each function).

EDIT : the last sentence is unclear: by character I mean criteria shared by all objects

what i was thinking about:

Tables:

• of users
• objects
• feat1rates
• feat2rates
• feat3rates

and relationships: the object has a lot

• feat1rates
• feat2rates
• feat3rates

The user has a lot

• feat1rates
• feat2rates
• feat3rates
