系统上线 [词典] online implementing; [例句]而新的SAP系统上线前,如何将原有系统中的大量数据传输至SAP系统;But before the implementation of SAP system, how should a large amount of data transfer to SAP system?
中文有问题,应该是:系统上线 就是 将开发完的系统放到真实的运营环境中进行使用和测试。System launching means to put the developed system onto live (production) environment for using and testing/trial running.
