I'm a PHP developer (not a DBA) and I've been working with Oracle 10g XE for a while. I'm used to XE's simplified user management:

1. Go to Administration/ Users/ Create user
2. Assign user name and password
3. Roles: leave the default ones (connect and resource)
4. Privileges: click on "Enable all" to select the 11 possible ones
5. Create

This way I get a user that has full access to its data and no access to everything else. This is fine since I only need it to develop my app. When the app is to be deployed, the client's DBAs configure the environment.

Now I have to create users in a full Oracle 11g server and I'm completely lost. I have a new concept (profiles) and there're like 20 roles and hundreds of privileges in various categories.

What steps do I need to complete in Oracle Enterprise Manager in order to obtain a user with the same privileges I used to assign in XE?

==== UPDATE ====

I think I'd better provide a detailed explanation so I make myself clearer.

This is how I create a user in 10g XE:

Roles:
    [X] CONNECT
    [X] RESOURCE
    [ ] DBA
Direct Asignment System Privileges:
    [ ] CREATE DATABASE LINK
    [ ] CREATE MATERIALIZED VIEW
    [ ] CREATE PROCEDURE
    [ ] CREATE PUBLIC SYNONYM
    [ ] CREATE ROLE
    [ ] CREATE SEQUENCE
    [ ] CREATE SYNONYM
    [ ] CREATE TABLE
    [ ] CREATE TRIGGER
    [ ] CREATE TYPE
    [ ] CREATE VIEW

I click on Enable All and I'm done.

This is what I'm asked when doing the same in 11g:

Profile:
    (*) DEFAULT
    ( ) WKSYS_PROF
    ( ) MONITORING_PROFILE
Roles:
    CONNECT:
        [ ] Admin option
        [X] Default value
