oracle中schema指的是什麼？ .

我們先來看一下他們的定義：
A schema is a collection of database objects (used by a user.).
Schema objects are the logical structures that directly refer to the database’s data.
A user is a name defined in the database that can connect to and access objects.
Schemas and users help database administrators manage database security.
