For buyers contracting authority
Pick 48614000 when the contract's point is capturing data and bringing it in, rather than storing, managing or modelling it. Sensor and telemetry capture, feed ingestion, monitoring and import tooling all point here. If the deliverable is the database platform that holds the data, that is the database-management system code (48612000) or the database software package (48611000) instead.
The boundary that trips contracting authorities is the sibling 48613000, Electronic data management (EDM). EDM is about handling and controlling documents and records once they exist; an acquisition system is about getting fresh readings or feeds into the system in the first place. Where a single contract spans both, set the primary CPV code by the dominant purpose.
One more thing to watch: an acquisition system often arrives bundled with the sensors, transmitters or instruments it reads from. The hardware itself belongs under its own equipment code; keep the contract here when the software capture layer is what the authority is mainly procuring, and tag it elsewhere when the iron dominates the spend.
