The first step in making a decision based on data comes from accurately acquiring it. Analog data comes from acquiring natural phenomena such as temperature, strain, pressure, and so on. Because the varied sources of analog data are so great, each system requires specific sensors and actuators (if used in a controls application) to meet the needs of the type and magnitude of natural phenomena being measured.
This is a valuable piece of an end-to-end Big Data solution because these systems (CompactRIO, PXI, NI CompactDAQ) help connect the benefits of precise data acquired from a sensor to the benefits of in-depth data analysis, usually while the data is real time or early life. The system nodes are network-connected hardware (with associated software) that perform A/D conversion, conditioning, and early analysis of the data acquired and help it move past "the edge" to the switch and server where it is stored and will likely undergo further analysis.

Once through Tier 2, the data moves past "the edge" and usually hits a network switch and then a server where it can be stored and undergo further analysis. This is the point at which customers can realize a great value from the data they’ve acquired and where many engineering, scientific, and business decisions are made. This tier also includes the cloud, a growing and appealing IT infrastructure for NI customers. In addition, it is within the IT infrastructure that much of NI’s systems management and RASM software is run, affecting NI system node (CompactRIO, PXI, NI CompactDAQ) products. This is further explained below.
