In Data Vault modeling, large numbers of entities and joins can look intimidating — but the real problem isn't how many joins you have, it's how complex they are. In this session we break down how bridge tables and PIT tables work together to reduce that complexity, turning expensive left outer joins into simple inner joins. We also cover practical techniques for keeping your model lean: combining satellites across sources and tenants, avoiding unnecessary splits, choosing business keys that exist across multiple systems, and building small use-case-tailored information marts instead of monolithic data marts. Plus, how modern commercial optimizers can automatically eliminate joins you don't need. "Data Vault Friday", a new live session every week.
