I’m building an internal security tool and need a solid PostgreSQL foundation that starts as a single, multi-tenant database yet can be cleanly split into separate databases—and separate servers—later on. The first release will concentrate on storing architectural components (a very well defined structure) alongside threat-intelligence data (mapped to the components metadata), so the schema must keep cross-tenant isolation strict while still allowing swift relational join matching across those two domains. What I need from you • A full relational schema (ERD and DDL) optimised for multi-tenant operation—think shared-table with isolated tenant-id or schema-per-tenant, whichever you can justify—and documented so the eventual extraction path is cle...

The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I ne...
