Abstract
DarkSide-20k is an underground direct dark matter search experiment designed to reach a total exposure of 200 tonne-years nearly free from instrumental backgrounds. The detector's core is a dual-phase Time Projection Chamber (TPC) filled with 50 tonnes of low-radioactivity liquid argon. The TPC wall is surrounded by PMMA acting as a neutron Veto, immersed in a 35-tonne argon bath.

The key technological innovation consists in instrumenting the TPC and Veto volume with silicon photomultiplier (SiPM) arrays, for a total area of 27 m$^2$.
The whole production comprises around 250,000 single components to be assembled in the 648 photo-detector units that will instrument the TPC and the Veto.
The proceeding focuses on describing the database infrastructure solution used to keep track of all the photo-detector components during the construction phase and the relative tests, in order to ensure a precise quality assurance and quality control through all the production.
