1) Executing an action in the DDL creates an object in the database; in contrast, a java or C++ declaration is simply an abstraction used in the program.
2) They do not allow consistency constraints to be specified
3) DDL supports access rights to different users; Java and C++ do not
4) Java and C++ have more complex types, such as arrays and objects
5) A database DDL is focussed on specifying types of attributes of rela- tions; in contrast, a programming language allows objects, and col- lections of objects to be created.
