IT = Internal table
Both are SQL data objects, and are similar in writing. The most important thing is that the storage and running processes on the server are almost the same, both of which are stored in the SQL statement set and are compiled before running, that is, you do not need to re-compile each time, which can greatly improve the execution efficiency.
