Graphical Programming

Since LabVIEW diagrams are data flow driven, the sequence in which the various operations in the VI are executed is not determined by the order of a set of commands. Rather, a Block Diagram node executes when data are present at all of its input terminals. As a result, in the case of the Block Diagram in Figure 12.4, one does not know whether the Add node or the Subtract node will execute first. Get price

What is flow control?

Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace. Too much data arriving before a device can handle it causes data overflow, meaning the data is either lost or must be retransmitted. Get price

Data Warehouse Architecture, Concepts and Components
