被忽略 (帮助)A database schema is a logical container for data structures, called schema objects. Examples of schema objects are tables and indexes.
Other types of objects are also stored in the database and can be created and manipulated with SQL statements but are not contained in a schema. These objects include database users, roles, contexts, and directory objects.
A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema. Schema objects can be created and manipulated with SQL.(schema是数据或模式对象的逻辑结构的集合,由数据库用户拥有,并且与该用户具有相同的名称,也就是说每个用户拥有一个独立的schema。)
