Dummy Database is built to solve a simple, yet annoying problem — generating realistic test datasets quickly, without writing scripts or juggling Excel files.
It’s designed for: - Developers needing dummy databases for prototyping & testing. - Analysts and BI specialists preparing demo dashboards. - QA engineers creating data scenarios for testing. - SQL learners who want practice datasets on demand.
What makes it special? - Create from simple tables to full relational databases with PK/FK. - 35+ data types including Numbers, Dates, Names, Booleans, etc. - Unique Event Sequences — simulate user actions and workflows. - Advanced data controls — outliers, nulls, repeats, distributions. - ERD visualization to map relationships. - Built-in PostgreSQL editor to query generated data. - Export as CSV, XLSX, SQL DDL, or full ZIP. - Free up to 10,000 records per table for registered users — no paywalls or limits.

DUMMY DATABASE's answer
A free, all-in-one data generation platform that builds everything from simple tables to full relational databases with advanced controls, unique event sequences, ERD visualization, built-in SQL querying, and multiple export formats — no limits, no paywalls.
DUMMY DATABASE's answer
Unlike other data generators, DUMMY DATABASE gives you full relational database creation, unique event simulations, advanced control over every field, built-in SQL querying, and generous free limits — so you can go from idea to test-ready data without restrictions, subscriptions, or hidden fees

I needed exactly this sort of tool for a reverse-engineering project! I was so invested I returned here to write this comment... Then spotted the other comments about "no Firefox support". Indeed, visually broken "Browser Not Supported" popup appears. Darn. Disappointing. Guess I will have to keep looking. Also... It doesn't look open-source and the comments about file access are valid. The functionality listed is... - Source: Hacker News / 7 months ago
Have you tried modeling it in falstad's onine circuit simulator? Source: about 3 years ago
Simulation is not viable for all but the most trivial circuits, and even then it won't catch things like a wrong footprint. I do occasionally use the Falstad simulator for simple analog circuits, but that just isn't possible with complicated digital ICs. Source: over 3 years ago
I don't know, but you could try simulating the circuit in Falstad circuit simulator to look at what is going on. Source: over 3 years ago
You can use Falstad to make sure you have a basic understanding of how relays work. Source: over 3 years ago
