One of the killer concepts of a bullet journal is the use of indices and spreads to provide an interlinked and searchable reference. If you go back in time, there are numerous journal and commonplace book organisational schemes.
Pages can be easily rearranged using a removeable binding (three-ring binder or various other options), or by using an unbound format such as index cards (the original database solution).
Data can be entered into a computer through scanning and handwriting recognition, though this is admittedly slow, cumbersome, and inexact. On the other hand, you may want friction between your paper-based and electronic data systems.
