    please make an effort

    on this site, we might help you with your homework, but we will not do the work for you

    draw an ER diagram and then tell us which parts of it you're not sure of

    Hi Sir, im sorry about that im not explained my problem well, this is my final project of BS (IT) VU Social Networking Forum, which is given to me from the University.
    I have just make the ERD with my level best but im still not satisfied with it. in my point of view that each entity is created with each user registration expect "user" entity because it is universal table am i right sir. but i have a problem with the "profile" entity is it created with each user or it may be a universal and please see the each relation and there is something wrong then please help me.

    Thumbs up you can read any database book

    go to CJ DATE one book for data base designing.
    try to set up normalization,
    go for data dictionary creation.
    set relation ship among tables.

    "It does not work" is not a valid problem statement.
