a database within a human resources database that stores the manager-subordinate relationship. we’ll impose the business rule that each manager may have one or more subordinates while each subordinate may have only one manager. how many tables shoud i make ? and how many rows and columns i should make. thanks in advance!

i want to make a database for a libary,but i don't know how to do this.how many tables i should be make? the fields i can think of are "id" "books name" "price" "ISBN" "author's name" "category" "the press" "the time of the publication". how to make the database? if i want to design a database?the first i must do is ?the second...? the third...? any tips would be appreciated!

Thanks a Lot for spending time with my questions. But it would be helpful for me,if u explain the first ,second,third normal form with some simple examples here....so that I can understand it very clearly................

i can't understand. table1: StudyNo | Name | Sex | Email | ClassNo 01 john Male [email protected] 200401 02 mary famale [email protected] 200402 table2: ClassNo | ClassAddress 200401 Abuilding1 200402 Abuilding2 are fit for the second NF,the primary key is StudyNo ,ClassNo why the first doesn't fit for the second NF

StudyNo | Name | Sex | Email | ClassNo | ClassAddress 01 john Male [email protected] 200401 A building 1 02 mary famale [email protected] 200402 A building 2 the above is a table. StudyNo is the primary key,a friend of mine said the above is fit for the first normal form,but doesn't fit for the second.the reason is "ClassAddress" partial dependencies on the key ClassAddress, why?who can explain it to me! thanks very much.

i am a newbie of php,maybe this is a simple and a little silly question,but i want to know the true principle of it.hope someone can help me . Q: there is a function,and have a form like this $a->b in a function bracket.what is $a->b mean and have what effect? the sign '->' mean is? eg: format_date($comment->timestamp) anyone's reply is appreciated!

how many ways that we can do to output an array's result, eg:$row=array{...} as far as i know,the followings are the output's format,which is right?and why? echo $row[$key]; echo $row[key]; echo $row['key']; i have tested the echo $row[$key]; is wrong, and what is the difference of the rest.thank you!
