systembase

SystemBase is a term used in computing with several meanings. In Unity's Data-Oriented Tech Stack (DOTS), SystemBase refers to a base class used to implement ECS (entity component system) systems. Developers extend SystemBase to provide an OnUpdate function for system logic, and the class offers access to the world, entity queries, and component lookups while integrating with Unity’s job system and scheduling.

In broader use, a system base or base system describes the foundational layer of a computer system. This can mean the minimal software stack required to boot and run a device, a baseline configuration used for benchmarking, or the base address map that hardware uses to locate memory-mapped peripherals. In software architecture, a system base layer may house core services such as configuration, logging, error handling, and dependency management, serving as a stable foundation for higher-level modules.

Because the term is context-dependent, documentation or project glossaries should be consulted to determine the precise meaning in a given setting. When encountered in Unity-related material, SystemBase usually denotes a concrete class for building ECS systems; in other domains, it may simply refer to aBaseline or foundational system used for comparison, integration, or deployment.
