What is RTD?
Real-time data (RTD) is information that is distributed directly after it has been gathered. There is absolutely no delay in the timeliness of the data delivered. Real-time data is often used for navigation or tracking.Some uses of the term "real-time data" confuse it with the term dynamic data. The presence of real-time data is actually irrelevant to whether it is dynamic or static. Real-time analytics is the use of, or the capacity to use, data and related resources as soon as the data enters the system. The adjective real-time refers to a level of computer responsiveness that a user senses as immediate or nearly immediate. Real-time analytics is also known as dynamic analysis, real-time analysis, real-time data integration and real-time intelligence.
Technologies that support real-time analytics include:
- Processing in memory (PIM) -- a chip architecture in which the processor is integrated into a memory chip to reduce latency.
- In-database analytics -- a technology that allows data processing to be conducted within the database by building analytic logic into the database itself.
- Data warehouse appliances -- combination hardware and software products designed specifically for analytical processing. An appliance allows the purchaser to deploy a high-performance data warehouse right out of the box.
- In-memory analytics -- an approach to querying data when it resides in random access memory (RAM), as opposed to querying data that is stored on physical disks.
- Massively parallel programming (MPP) -- the coordinated processing of a program by multiple processors that work on different parts of the program, with each processor using its own operating system and memory.
