Need help setting up DB environment for homework assignment in Database SQL class. I am having trouble with MySQL installer. Can anyone help me?

Do you have any specific examples to back up your assertion that many-to-many links cannot be stored in a relational database? If you have, we'd appreciate it if you'd tell us about them.

Can you explain the difference between DBMS and RDBMS?

please answer DBMS ques asap! AUMarket is a retail company whose database system uses the discretionary access control to manage its data. Jennifer is the DBA of this database system and also the owner of a table called PAYMENT. Jennifer grants SELECT on the table PAYMENT to the database user Lee as follows:  GRANT SELECT ON PAYMENT TO Lee; However, Jennifer does not want to grant any privileges on the table PAYMENT to the database user Paul. Paul knows very well about database hacking techniques. If Paul does not have any privilege on PAYMENT but he knows that Lee has the SELECT privilege on PAYMENT, is it possible that Paul can hack the database in order to obtain the information of all records in the table PAYMENT? If impossible, you need to explain why it is impossible. If possible, you need to explain how Paul can obtain the information.
