In PeopleSoft Financials, a group of application processes (performed in a defined order) that users can initiate in real time, directly from a transaction entry page.
a collection of related processes, such as a shell pipeline, all of which have been assigned the same process-group identifier
a collection of sequentially and logically dependent processes that portrays a summarized view of a scenario
an ordered collection of processes, and each process is uniquely identified by its rank within the ordering
A collection of processes that permits the signalling of related processes. Each process in the system is a member of a process group identified by a process group ID. A newly created process joins the process group of its creator.
A collection of related processes each having the same process group ID.
A set of processes that can be treated as a single entity for some purposes, such as synchronization and broadcast or multicast operations. In some parallel programming systems there is only one process group, which implicitly contains all processes; in others, programmers can assign processes to groups statically when configuring their program, or dynamically by having processes create, join and leave groups during execution.
A process group represents a group of processes as a single icon on the diagram. This group may also contains internal stores and flows to accomplish its purpose -these are 'hidden' within the process group. Process group are used to reduce the complexity of any one data flow diagram by combining related functions and naming the combinations for the general function that this group carries out. In the figure "change to new solution" is a process group comprising processes "control solution change","determine new solution","detect empty tank", etc. A process group is drawn on the diagram as a solid circle, it cannot be visually distinguished from a data process without looking at its specification.
In POSIX-conformant operating systems, a process group denotes a collection of one or more processes. The collection is identified by a positive integer, the process group ID, which is the process identifier of the process that is (or was) the process group leader.
