It asks: Create a user named 'T15'. This should use the default tablespace 'users' fee should be unlimited and must have a temporary tablespace called 'temp'. Show SQL used to create the user with all the above requirements: Give the user permissions so you can create sessions, tables, users, scripts, views, and materialized views.

For the purpose of avoiding having to update it manually, and already have the version ER graphic, you want to generate this chart using reverse engineering options incorporating SQLDeveloper. Follow the steps below to get updated diagram (it is assumed that you have installed in Spanish): Since SQLDeveloper menu 'File' option 'Data modeler' option 'Import' option 'Data Dictionary'. In the Wizard window, select the user T15. Enter your login password as prompted. Tap the button 'Next'. As prompted to choose a scheme, check the 'T15'. Tap on the button 'Next'. As window appears where you can choose objects to import, select all the tables. Tap on the button 'Next'. Tap on the button 'term'. ER diagram generated, minimally sorting tables to avoid excessive crosses the lines of relationships.
