ühendugi

Ühendugi is a term used in Estonian information technology and systems engineering to describe the capacity of a system, component, or service to remain interoperable and connected with other systems over time. It encompasses compatibility of interfaces, data formats, and communication protocols, as well as the ability to incorporate updates or changes without breaking existing integrations.

Etymology and meaning: the word is formed from ühendus, meaning connection, with a suffix that signals a state or quality. In use, ühendugi refers to the enduring ability to connect diverse modules, platforms, or services despite evolution in software and hardware environments.

Applications and usage: in project planning and architecture design, engineers assess ühendugi to ensure long-term viability of integrations. It guides decisions on API design, data model flexibility, modularity, versioning strategies, and migration paths. The concept is particularly relevant in environments with multi-vendor components, cloud deployments, or legacy systems that must interface with newer technologies.

Measurement and assessment: while not universally standardized, a practical approach involves evaluating supported interfaces across versions, data format extensibility, backward and forward compatibility, and the rigor of test coverage. Some organizations propose an explicit ühendugi index to quantify interoperability resilience.

Limitations and scope: as a relatively informal term, use of ühendugi varies by organization and context. It is commonly discussed in the same domain as interoperability and compatibility, but may lack formal metrics or universal definitions in standards bodies.
