...into my PostgreSQL database through Tally Definition Language. The goal is seamless, automated integration—no manual exports, no Excel hops—so that every voucher, ledger, and stock movement recorded in Tally lands in dedicated tables inside Postgres in near-real time. Here’s what matters to me: • TDL code that hooks into the relevant Tally events and packages the data for transfer. • A lightweight service or script on the Postgres side that receives the payload and inserts or updates the right tables. • Clear mapping documentation so I can see which Tally fields end up in which database columns. • Basic error handling and a simple log so I know when something fails. I already have the database schema and connection details ready; yo...

Deliverables will be: 1. A fully populated SQL database (MySQL or PostgreSQL are both acceptable) matching the structure I provide. 2. A brief validation report confirming record counts, any skipped entries, and issues resolved. Accuracy is more important than speed, but I would like the initial load completed within one week once access is granted.

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...
