i am not good with table relationships on primary foreign key and 1-n and n-1 etc relationships, data model diagram reading esp when there are 100 tables connecting one other? how do i go about digesting those diagrams.
shoe i take printout and using a pencil mark physically which table is talking to which super table and sub table.
please advise any good links, resources, training, free video tutorials on this.
this concept is same across any kind of database right?
