How to have essentially DML and no DDL for a user schema? [message #301476]

Ok- this may seem like an overly pedestrian question, but...

How would I ensure that a user has ONLY the permissions to SELECT, INSERT, UPDATE, DELETE and EXECUTE PACKAGES/PROCEDURES/FUNCTIONS in their OWN schema, and no more?

So, I don't want them to be able to create or drop tables, indexes, functions, packages, etc.- even in their own schema.
But, they can connect, and use the objects that are created for them (by SYS), and no more.

...Assume this functionality would be implemented using a role, which would be customized, and then granted to the user.
Assume the user would have unlimited (DEFAULT) resources.
Also assume that the best method of implementation would be one where the role is created just once, and then does not require modification if SYS adds a new table / trigger / procedure / function / view / package, etc to said schema...

...The idea behind this is to have a main user that our application server connects to (and who owns the database objects for our application), but to which our developers (or hackers) can't tinker with in order to play at being DBA.

Any help would be greatly appreciated.

Don't give them other privileges.

Don't grant them roles or privileges to create objects.
Don't give them quota on any tablespace.

This is a bad idea.
Each user must have their account with only the privileges they need to do their job.
Owner schema should be locked and never use (or maybe during application upgrade).
