Operational amplifier applications
Operational amplifier applications, also called op-amp circuits, are analog circuits built around a high-gain differential amplifier whose external feedback networks set functions like amplification, arithmetic, filtering, and oscillation.
Operational analytics
Operational analytics (also operational BI, operational intelligence) applies analytics directly to operational systems like POS, ERP, IoT, and CRM in near real time to monitor, optimize, and automate day-to-day business processes.
Operational data store
Operational data store (ODS), or operational data layer (ODL): a subject-oriented, integrated, near-real-time database consolidating data from multiple transactional systems for operational reporting, distinct from data warehouses holding historical analytical data.

An operational design domain (ODD) is the set of operating conditions, such as road type, speed, and weather, under which a driving automation system is designed to function.
Operational modal analysis
Operational modal analysis (OMA) is a response-only structural dynamics method that estimates natural frequencies, damping ratios, and mode shapes from ambient vibration, without measuring excitation forces.
Operational profile (software)
An operational profile is a quantitative characterization of how a software system will be used, listing its operations and their probabilities of occurrence; John D. Musa introduced the concept.
