从这个图中可以看出，数据库和模式是从SQL对象派生而来的，因此具有属性，例如名称、描述和标签。
From this figure, you can see that databases and schemas are derived from the SQL object, and therefore they have properties, such as name, description, and label.

Intended use cases: Connecting to and browsing Derby or DB2 databases, creating schema objects, running and creating SQL scripts, loading and unloading tables, and Derby to DB2 migration.
使用模式控制对数据库对象的访问。
Rails迁移特性可以帮助应用程序开发人员管理这种模式演变，便于在应用程序代码与数据库对象之间同步更改。
The Rails migration feature helps application developers manage this schema evolution, making it easy to synchronize changes between the application code and the database objects.
Hibernate和TopLink等工具大大简化了把对象模型映射到关系数据库模式的过程。
Tools such as Hibernate and TopLink have made it much easier to map an object model into a relational database schema.
Pixie提供了略微不同的方法，它不要求从类到数据库的模式或映射—它只存储对象。
Pixie offers a slightly different approach in the sense that it doesn't require a schema or map from the class to the database — it just stores objects.
每个数据库对象有0到多个(0. .n)模式，每个模式可以有0到多个(0 . . n)表、索引、用户定义类型和例程等。

Create, view, and edit database objects (such as tables and schemas).
在这个例子中，所有未限定的sql语句(即没有使用模式名限定其中的数据库对象的语句)会使用模式u1。
In this case, all unqualified SQL statements (statements that did not qualify database objects with a schema) would use the schema U1.
如果恢复的任何对象引用另一个模式中的对象，而被引用的对象在目标数据库中不存在，那么这个过程将失败。
If any object to be restored references an object in another schema, and this object does not exist in the target database, the procedure will fail.
