The costs can be low if the data sources have similar data models and only simple transformation operations are required.
如果数据源具有类似的数据模型,并仅需要执行简单的转换操作,那么其成本可能很低。
This reduces development efforts for new transformation jobs and simplifies administration — thus reducing operational costs.
这可以降低新的转换任务的开发成本并简化管理,从而降低操作成本。
Although benefits achieved through services reuse leading to development and integration costs reduction are essential, in the long run they are secondary to SOA's business transformation value.
尽管通过服务重用实现的好处可以减少开发和集成的成本这一事实非常重要,但就长远来看,SOA的业务转换价值却更为重要。
