'''Process oriented programming''' is a [[programming paradigm]] that separates the concerns of data structures and the concurrent processes that act upon them. The data structures in this case are typically persistent, complex, and large scale - the subject of general purpose applications, as opposed to specialized processing of specialized data sets seen in high productivity applications (HPC). The model allows the creation of large scale applications that partially share common data sets. Programs are functionally decomposed into parallel processes that create and act upon logically shared data.
The paradigm was originally invented for parallel computers in the 1980s, especially computers built with [[transputer]] microprocessors by [[INMOS]], or similar architectures. It evolved to meet deficiencies in the [[message passing]] paradigm of [[Occam programming language|Occam]] and enable uniform efficiency when porting applications between distributed memory and shared memory parallel computers.
The first example of the paradigm appears in the programming language [[Ease programming language|Ease]] designed at Yale University<ref name="process">{{cite paper | last=Ericsson-Zenith | authorlink=Steven Ericsson-Zenith | |title=Programming with Ease; Semiotic definition of the language|publisher=Yale University, Computer Science Technical Report YALEU/DCS/RR-809|date=1990|}}</ref><ref name="process2">{{cite book | last=Ericsson-Zenith | authorlink=Steven Ericsson-Zenith | |title=Process Interaction Models|publisher=Paris University|date=1992|}}</ref> in 1990. Similar models have appeared since in the loose combination of SQL databases and objected oriented languages such as [[Java (programming language)|Java]], often referred to as object-relational models and widely used in large scale distributed systems today. The paradigm is likely to appear on desktop computers as microprocessors increase the number of processors ([[multicore]]) per chip.
