2.Ideally,a database language must enable us to create the database and table structures;it must enable us to perform basic data-management chores(add,delete,and modify data);and it must enable us to perform complex queries designed to transfrom the raw data into useful information.Moreover,it must perform such basic functions with minimal user effort,and its command structure and syntax must be easy to learn.Finally,it must be portable;that is,it must conform to some basic standard so that we do not have to learn from scratch when we move from one RDBMS to another.
