Oracle data base management system uses command line user interface which is very difficult to deal with. You will get to know the difficulty once you use the same. For instance, you will not be able to go back once you have pressed the enter key (to go to new line). Hence editing is very difficult once you have written and executed the query. You have to use one extra editor for this purpose. But all other DBMSs provide a pretty good user interface with all the advanced functionality.
