About

rdbms-playground is a cross-platform terminal app for learning relational database concepts - tables, columns, primary and foreign keys, relationships, indexes, queries, and query plans - in a safe sandbox. It's a teaching tool, not a database administration tool: it meets beginners with guided, keyword-based commands (simple mode) and grows with them to raw SQL (advanced mode), so the same playground works from "what is a primary key?" through to writing real queries and reading their execution plans.

Security

No known CVEs for RDBMS Playground.

Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
