  • a swirnlane is able to move a specific, finite amount of data between the two devices. For example, a single swirnlane might: reliably cany and have incorporated into the data store, the data equivalent of .5 seconds worth of data from 10 sensors in 5 seconds, this being its capacity. Attempts to place 5 seconds worth of data received from 6 sensors using one swirnlane would result in data loss.

For example, given the node “James R,” name information for a person, qualifying properties might be "183 cm tall", “DOB 08/13/1965" and "speaks English", Similar to the use of properties to further describe the information in a node, a relationship between two nodes that forms an edge can be qualified using a "label".

Such linearization can result in exponential growth of resource consumption. The most, sensible approach to overcome possibility is to introduce new transformation pipelines just as they are needed, creating only those that are ready to compute. Such method results in tra sformation graphs which are highly variable in size and node, edge composition as the system processes data streams.

Transformations may comprise any combination of machine, human or machi e-human interactions Transformations need not change data that enters them, one example of this type of transformation would be a storage transformation which would receive input and then act as a queue for that data for subsequent transformations. As implied above, a specific transformation may generate output data in the absence of input data. A time stamp serves as a example.
