1. The basic definition of real-time data is that it is data that is not kept or stored, but is passed along to the end user as quickly as it is gathered. It is important to note that real-time data does not mean that the data gets to the end user instantly. There may be any number of bottlenecks related to the data collection infrastructure, the bandwith between various parties, or even just the slowness of the end user`s computer. Real-time data does not promise data within a certain number of microseconds. It just means that the data is not designed to be kept back from its eventual use after it is collected.
2. Real-time data is information that is delivered immediately after collection. There is no delay in the timeliness of the information provided.
