为企业定义 Web 上的实时性 [英] Define realtime on the web for business

问题描述

听到业务支持者对基于 Web 的系统使用术语实时"，这让我很抓狂.我在房间里变得疯狂，高呼:网络上没有实时性这种东西！我们从事银行业务，而不是火箭发射/船舶导航/飞机自动驾驶仪业务！"

It drives me nuts to hear business proponents using the term realtime for web-based systems. I'm becoming the crazy in the room, chanting, "There is no such thing as realtime on the web! We're in banking, not the rocket launch/ship navigation/airplane autopilot business!"

在性能规格方面，有没有人比实时或其可怕的混合近实时更好?

Anyone have anything better for performance specifications than realtime, or its horrible hybrid, near-realtime?

推荐答案

在银行业的大部分时间里，实时"与日终"相反.

In the banking industry most of the time "real time" means the opposite of "end-of-day".

因为在过去没有互联网/内联网/局域网/广域网这样的东西，所有的平衡都是在一天结束"时完成的.在某个银行账户的一个分行进行的交易不知道在另一个分行进行的交易；所有的余额解决都将在一天结束时发生.当大型机采用相同的规则时:解决方案由计算机通过一个长期运行的进程完成，通常在晚上 9 点到午夜 12 点之间运行.

Because there was no such thing as internet/intranet/LANs/WANs in the old days, all balancing is done at "end-of-day". Transactions done in one branch with a certain bank account are oblivious of the transactions done in another; all of the balance resolution will occur during end of day. When mainframes came in the same rule applied: resolutions are done by computer by a long-running-process usually run between 9PM and 12 midnight.

这就是当前余额"和可用余额"等术语背后的原因，例如，可用余额是由日终流程确定的前一天账户余额；当前余额是应该的，但你还不能碰它，因为银行不确定你是否在其他地方进行了一些交易.

This is the reason behind terms such as "current balance" and "available balance", e.g., available balance is what has been determined by the end-of-day process as an account's balance for the previous day; current balance is what it's supposed to be, but you can't touch it yet since the bank is not sure if you've made some transaction somewhere else.

随着 ATM、互联网和其他互联技术的出现，实时"余额解析现在成为可能:取款、在线交易、购买借记等将立即反映在客户的银行账户中，无需需要等待一天结束的处理.

With the advent of ATMs, the internet, and other interconnectivity technologies, "real time" balance resolution is now possible: a withdrawal, an online transaction, a purchase debit, etc will immediately be reflected in the customers' bank accounts without the need to wait for end-of-day processing.
