This document provides technical guidance on considerations for relational database design when building a system that holds beneficial ownership information. In particular, it focuses on the requirements for publishing data to meet the Beneficial Ownership Data Standard (BODS). Most of these recommendations will also suit the creation of any system which aims to ingest declarations of beneficial ownership and create auditable records.

This guidance note is designed for use by technical professionals, especially those with a role in the database design and technology architecture of company registers and/or sector registers that will publish to BODS.
