Users and Basic Security

After you've installed the binaries, created a database, and created tablespaces, one of your next tasks is to create users and configure the security of the newly created accounts. A user is an account through which you can log in to the database and establish a connection. A schema is a collection of database objects (such as tables, indexes, and so on). A schema is owned by a user and has the same name as the user. The terms user and schema are often used synonymously by DBAs and developers. Distinguishing between the two terms isn't usually important, but there are some subtle differences.
