AI can read your tables. It can't tell how a relationship, its accounts, their products and their balances connect across the core, GL and CRM. Preql maps how each system represents those concepts, and business owners approve one definition for each, with version history and lineage back to source.
1. Concepts live in different systems. Customers in the CRM, accounts in the core, balances in the GL.
2. Relationships aren't written down. Which accounts belong to which relationship depends on rules people carry in their heads.
3. Every step is a guess. An answer that crosses three systems compounds three guesses.
