marmelab web developer Thiery Michel shares in this article his use of PostgreSQL features that allow us to draw certain data validation logic away from the application layer, and into the database. The proposed solutions in some instances can be more elegant than a purely application layer data validation approach.

Code changes have AI review tools. Data changes don't... until now.

Our own Kent Chen wrote about how the team built a multi-agent system with Claude Agent SDK and MCP that reviews data changes in every dbt PR. Orchestrator + two specialist agents using 6 Recce MCP tools for lineage diffs, schema diffs, row counts, and custom queries.

AI Data Review lands in the PR automatically. No manual queries.

One of the new features in SQL Server 2025 is that you can now use regular expressions directly in your T-SQL queries. Now, regular expressions (or RegEx) have never been a syntax that’s easy…
