While the Mainframe maintains case and criminal files, the Denabase is an EMP-proof archive that stores miniaturized hard files on all registered LA civilians. Akin to archaic microfiche, the Denabase can magnify each person’s file sorted by their DNA ID code. Entries go back decades, and (due to Blackout data corruption) often contain the only pre-2020 records, though some files are incomplete. The data is too dense for humans to review without the terminal, but Replicants can “run it raw” and search DNA code manually for faster results. The Denabase is regularly updated as a security measure, and some prefer its discretion of researching records off the Mainframe’s radar.
