定义Web业务的实时 [英] Define realtime on the web for business

问题描述

这驱使我坚果听到使用基于Web的系统术语实时商业支持者。我变得疯狂的在房间里，高喊：有是在网络上实时没有这样的事！我们是银行，而不是火箭发射/船舶导航/飞机自动驾驶仪的企业！

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!"

任何人有任何的性能规格比实时的，或者它的可怕的混合，接近实时的？

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实时是指最终的天相反。

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

由于有作为的Internet / Intranet /局域网/广域网在过去没有这样的事，所有的平衡是在最终的天完成。在一个分支做具有一定的银行账户交易漠视另一种做交易的;所有的平衡决议案将一天结束时发生。当大型机排在相同的规则适用于：分辨率是由计算机完成的一个长期运行的过程通常是晚上9点到12之间运行午夜

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.

这是背后的术语，如当前余额和可用余额，例如原因，可用余额是多少已经被结束一天的过程中作为一个帐户为previous天的余额确定;当前余额是它应该是，但因为如果你已经取得了一些交易的其他地方，银行是不知道你无法触摸它。

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.

通过自动取款机的出现，互联网和其他互联技术，实时平衡的决议，现在可以：提款，在线交易，购买借记卡，等会立即反映在客户的银行账户，而不需要等待最终的日处理。

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.
