Process-oriented programming is a

programming paradigm A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. A programming language can be classified as supporting one or more paradigms. Paradigms are separated along and descri ...

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 The transputer is a series of pioneering microprocessors from the 1980s, intended for parallel computing. To support this, each transputer had its own integrated memory and serial communication links to exchange data with other transputers. ...

message passing In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer. The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting ...

paradigm of Occam to enable uniform efficiency when porting applications between distributed memory and shared memory parallel computers . The first such derived example appears in the programming language Ease designed at Yale University in 1990. Similar models have appeared since in the loose combination of SQL databases and objected oriented languages such as

, 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. The

Actor model The actor model in computer science is a mathematical model of concurrent computation that treats an ''actor'' as the basic building block of concurrent computation. In response to a message it receives, an actor can: make local decisions, create ...

might usefully be described as a specialized kind of process-oriented system in which the message-passing model is restricted to the simple fixed case of one infinite input queue per process (i.e. actor), to which any other process can send messages.
