请注意，可以作为任何系统用户从应用程序连接 DB2 数据库，对其中的表有完全访问权。
Please note that you can connect and have full access to the tables in the DB2 database as any of the system users from within your application.
一旦成功建立连接，应用程序就会在一个表中显示雇员记录。
Once the connection is established successfully, the application will display employee records in a table.
其他想要并发访问相同表中的数据的应用程序不需要与数据库断开连接，并且可以继续进行该表中的读或写操作。
Other applications that want to access data in the same table concurrently do not need to disconnect from the database, and are free to pursue read or write operations in that table.
