You also create the canvas context object, as this is the object you use to do all of the actual drawing.
但只有在你连接到上下文对象的时候，你才可以修改对象并把它们保存回数据库。
You can change objects and save them back to the database, but only if you are connected to a context object.
如果连接属性与一个可信上下文对象的定义相匹配，则那个连接被称作可信连接。

DB2 USES the create trusted context statement to create trusted context objects.
其次，它在队列连接中创建一个队列会话，并通过查找上下文对象获得一个指定名称的队列。
From the queue connection factory, a queue connection is created. Next, a queue session is created from a queue connection and a queue is retrieved by looking up the context object with a queue name.
就像数据库连接那样应该非常快，一旦该上下文对象超出范围，数据对象实质上就进入只读状态。
Once the context object goes out of scope, which like a database connection should be very quickly, the data objects essentially become read-only.
