它从数据源驻留的后端系统开始，到API连接，到应用程序服务器，到WSP网关，然后到手持单元。
It goes from the backend system, where the data source resides, to the API connection, to the application server, to the WSP gateways, and then to the handheld units.
许多服务将继续使用包含它们自己数据库的遗留或COTS系统，并且服务单元实现的异质性是SOA机动性的基础。
Many services will continue to use legacy or COTS systems that incorporate their own databases [and] heterogeneity of service unit implementation technologies is fundamental to SOA agility.
单元测试意味着在隔离环境中运行，所以不会运行数据库和Web服务器，最重要的是不会发生与Grails 相关的元编程。
Unit tests are meant to run in isolation, which means that no database is running, no Web server is running, and — most important — no Grails-related metaprogramming occurs.
