在软件生命期尤其是长期的支持和维护过程中(这也是应用程序生命周期中最昂贵的一个阶段)，应用程序和领域模型的重用将提高ROI。
ROI will rise from the reuse of application and domain models across the software lifespan, especially during long-term support and maintenance, the most expensive phase of an application's life.
如果我们将应用程序设计为只在便于管理的处理阶段中打包和交换少量XML数据，那么就可以减少这些盲点，使应用程序更易于维护。
If you design applications that package and exchange small, controlled chunks of XML data in manageable processing stages, you reduce these blind spots and make the application easier to maintain.
我们高度推荐您尽可能利用这些应用程序范围的参数，这样可以提高程序的可移植能力，并且简化将来的维护工作。
It is highly recommended that you utilize these application-wide parameters as much as possible to increase portability and to ease maintenance havoc in the future.
要么象更改帐户状态的副作用那样，程序应该自动备份；要么程序必须维护一个审计跟踪以便撤销更改。
Either the program should back up automatically as a side effect of changing the state of an account, or the program must maintain an audit trail that lets you undo the changes.
代码结构糟糕透了，程序员显然没有深入思考程序的正确性，算法，数据结构和可维护性。
The structure is appalling, and the programmers clearly didn't think deeply about correctness, algorithms, data structures, or maintainability.
它使用一个调度程序来发起周期性的事件，比如爬网程序执行和全文索引维护。
It USES a scheduler to initiate periodic events, such as crawler executions and full-text index maintenance.
相反，编码策略不需要进行上述维护工作，而且它对现有应用程序代码以及应用程序功能的影响也较小。
The encoding strategy, on the other hand, does not have the above-described maintenance effort, and it also has less impact on the existing application code as well as on application functionality.
优秀的应用程序设计和编码实践是实现高性能、可维护的应用程序的基础。
Good application design and coding practices are the cornerstones of high-performance, maintainable applications.
配置文件最适合存储这类数据，从而在修改这些属性的时候不需要重新编译应用程序，应用程序维护起来也更容易。
A configuration file is the best place to store this data, because it ensures that you can change these properties without recompiling the application, and it makes maintaining the application easier.
