    Erd

    I'm an absolute beginner. What possible advantages, in general, will have creating another entity with its own attributes instead of assigning those attributes to the parent entity? I'm trying to understand it more in depth, and see the possible scenarios in general/logical terms.
    Thanks

    You should start reading about normalizing databases. Search for database normal form and you should get plenty of materials.
