Reaaliaikaisilla

Reaaliaikaisilla is the plural adessive form of the Finnish adjective reaaliaikainen, which means "real-time" or "in real time". As an inflected adjective, reaaliaikaisilla is used when qualifying a plural noun in the adessive case, conveying meanings such as "with", "on", or "by" those real-time items (for example, "with real-time systems" or "on real-time devices").

The term appears frequently in technical and professional contexts: information technology (reaaliaikaisilla järjestelmillä — with real-time systems), telecommunications, finance (reaaliaikaisilla markkinat — with real-time markets), control engineering, gaming and live data monitoring. It signals that processes, data or interactions occur without perceptible delay, often with constraints on latency and timing guarantees.

In Finnish grammar, adjectives agree in number and case with the nouns they modify; thus reaaliaikaisilla must be paired with a plural noun in the adessive case (e.g., reaaliaikaisilla palveluilla — with real-time services). Related forms include reaaliaikainen (basic adjective), reaaliaikaiset (plural nominative), and reaaliaikaisuutta (partitive of the noun form reaaliaikaisuus, "realtimeness" or "real-time nature").

Usage examples:

- Reaaliaikaisilla järjestelmillä voidaan seurata tuotantoa välittömästi. (With real-time systems, production can be monitored immediately.)

- Päätökset tehtiin reaaliaikaisilla tiedoilla. (Decisions were made with real-time data.)
