Short description

A data object (sometimes also called information object) is a resource that can be attached to an EPC function by a data flow in order to highlight data processed by the function.


A data object is connected to a function by data flow connector, a straight line with an arrow in one direction. The arrow is at the end of the straight line, pointing towards the element to which the information is flowing. [1], [2] Data objects which are neither written nor read, but carried around, are connected to a function by an undirected connector. [2] A function is associated with none or more data objects and a data object is associated with one or more functions. [3], [4]


Data objects illustrate input data that serves as the basis for a function or output data that is produced by the function. [2], [4] A data object is not only data from databases, but can be any information from any source, digital or non-digital. [2]
