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.

When you use a transaction, the database tables/views/other resources used in the transaction are locked until the transaction is either committed or rolled back in order to ensure all modifications are either ALL made, or none of them made. Usually databases also have options on the level of locking used such as no one can read or make changes to those resources when locked, or users can’t make changes to the resources but they can read data in the tables/views/read access to resources.  Pick a potential problem with database locks on tables/views/resources and one popular way database administrators and / or database users use to address that problem?
