Finally, if your Java application system takes the framework of the presentation layer, service layer and persistence layer mentioned above, you can also develop a high quality application system without having to master the design pattern.

Strengthen the database environment for "operations" (disk space, data files, redo logs, tablespace, etc.) to monitor and alarm properly. If you do not do this, the client's IT environment will experience a lot of power outages and take a lot of time for Fault Repairs.
