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.

Our app puts three core values to the fore: simplicity, visualization, and consensus.

By creating an infinite canvas where cards, much like sticking notes, resemble a neatly organized collection of inter-related ideas. They serve as units of thoughts with clear borders, displayed on a squeaky-clean white canvas.

To preclude the document from becoming messy as the number of cards augments, we betted on functions that are clear-cut and intuitive. They include drag’n’drops; deep dive; tabs within a document; embedded pictures, videos, and links; sub-pages. As a result, the users get a well-organized, easy-to-navigate space.

Rather than providing bits and pieces of scattered information, the tool gives you a bird’s-eye view of the cards, creating the big picture.

Pillared by simplicity and visualization, the app offers a collaborative space for teams to work together in real-time, sharing cards and elaborating on ideas.
