The security section allows you to manage the currently
selected database. The objects that you can manage in this section are:
Users
Roles
Schemas
Asymmetric Keys
Certificates
Symmetric Keys
Clicking on the Users node lists all the users that belong
to the currently selected database. You will also be able to add a new user
Figure 23

You create a new user by providing username, login name,
default schema, specify schemas owned by the user, and the roles the user
belong to.
Roles
This section allows you to manage database roles. You can
create/modify/delete roles in a similar manner to creating and modifying users
Figure 24

Schemas
The schemas section is much similar to the above two
sections. You can create/modify/delete schemas from your database. In SQL
Server 2005, a schema is more like a container that can contain tables, stored
procedures, and other database objects. It is a logical grouping of the
database objects.
Creating a new schema is a very simply task to do
Figure 25

The Asymmetric Keys, Certificates, and Symmetric Keys nodes
are added to myLittleAdmin just to view and delete current objects only.
