Teradata Corporation

This is Teradata's core business: multi-year subscriptions that let customers run its analytics database, plus the support that keeps it working. A growing share now comes from cloud subscriptions rather than software installed on a customer's own servers, so the mix is shifting even as the total line shrinks. Because swapping out a company's core data warehouse is disruptive and costly, customers tend to stay for years once they commit.这是Teradata的核心业务：客户使用多年期订阅来运行其分析数据库，并获得配套支持服务。目前云订阅所占比例正在上升，取代安装在客户自有服务器上的软件，因此即使这条业务线整体在萎缩，其构成也在缓慢转变。由于更换公司的核心数据仓库既麻烦又昂贵，客户一旦采用往往会连续使用多年。

Teradata's services team helps customers set up, migrate, and get more value from its software, including moves from on-premises systems to the cloud. This work often opens the door to new or expanded subscription contracts, so it supports the recurring line even though it is a much smaller stream on its own.Teradata的服务团队协助客户安装、迁移其软件并从中获得更多价值，包括从本地部署迁移到云端。这类工作通常会带来新的或扩大的订阅合同，因此即使自身规模较小，也能支撑经常性收入这条业务线。

This covers one-time sales of older, install-it-yourself software licences and related hardware, a model Teradata is phasing out in favour of subscriptions. It is now a tiny slice of the business, and its shrinking size reflects how far the company has moved toward the cloud.这部分包括一次性出售较旧的、需自行安装的软件许可证以及相关硬件，Teradata正逐步淘汰这一模式，转向订阅制。目前它只占业务的极小一部分，持续萎缩的占比反映出公司已在很大程度上转向云端。
