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.
In CRM (customer relations management), real-time analytics can provide up-to-the-minute information about an enterprise's customers and present it so that better and quicker business decisions can be made -- perhaps even within the time span of a customer interaction. Real-time analytics can support instant refreshes to corporate dashboards to reflect business changes throughout the day. In a data warehouse context, real-time analytics supports unpredictable, ad hoc queries against large data sets. Another application is in scientific analysis such as the tracking of a hurricane's path, intensity, and wind field, with the intent of predicting these parameters hours or days in advance.
The adjective real-time refers to a level of computer responsiveness that a user senses as immediate or nearly immediate, or that enables a computer to keep up with some external process (for example, to present visualizations of Web site activity as it constantly changes).
