Aliprosessi

Aliprosessi is a Finnish term for a subprocess, used to describe a smaller unit of work within a larger process. It is applied in both business process management and computing to denote a component that performs part of an overall task.

In business process management, a subprocess is a defined sequence of activities that forms part of a larger process. It can be embedded within the parent process or invoked as a call to another process. Subprocesses support modularity, reuse, and readability by encapsulating complexity. They typically have defined input and output data, and start and end points, and may have their own variable scope. They can include exception handling and event-based boundaries. In diagrams such as BPMN, a subprocess is represented as a container that holds activities and can be expanded or collapsed for clarity.

In computing, a subprocess is a child process created by a parent process. It runs in its own memory space and system resources and often communicates with the parent via inter-process communication channels. Subprocesses are created by system calls such as fork and exec on Unix-like systems or CreateProcess on Windows. They enable tasks such as running external programs, performing separate computations, or implementing pipelines. The parent can wait for the subprocess, retrieve its exit status, or terminate it. Proper management avoids issues such as zombie or orphaned processes.

Summary: aliprosessi covers both conceptual subprocesses in process modeling and technical subprocesses in operating systems, reflecting a shared idea of decomposition of work into independently executable units.
