Database Sample: Open-Source Database Designs

About Database Sample

Database Sample offers a library of ready-made database schemas and diagrams, with browser-based tools to design, edit, and export schemas. It targets developers, students, researchers, and anyone needing database diagrams, samples, and schema generation in a no-install environment. Users can browse, edit, and generate schemas in the browser, with no account required to view or download designs.

The platform lets users write a schema description in DBML or describe it from the catalog, and then compares designs from the AI generator while highlighting missing keys and indexes as work progresses. It supports in-browser editing, SQL export, and sharing of results via a link that reproduces the answer.

Core capabilities include browsing 1,846 designs with diagrams and automated reviews, editing schemas in an editor, generating SQL and diagrams from text, and exporting SQL scripts, migrations, and ORM models. It also provides an SQL playground to run queries against generated data in SQLite or PostgreSQL and a dataset repository with multiple formats.

It describes platform access via web in-browser tools and notes CC0 licensing and no account required for many actions.

Frequently asked questions

What is databasesample.com?

databasesample.com is a library of open-source database schemas and downloadable sample datasets, with browser-based tools to design and convert schemas. Schemas, datasets and editors are free. Browsing, downloading and the editors need no account. An account is required only to sync your work across devices, publish a design or fork another member’s design.

Who can use databasesample.com?

Anyone. The schemas, datasets and tools are open to students, developers, researchers and anyone else who needs a database.

Are the database samples free?

Yes. Every database sample on databasesample.com is open source and free to download and use.

Can I publish my own designs?

Yes. Publishing needs no approval and takes effect immediately. A published schema appears under Designs and in the database catalog at the same address; a system design appears under Designs. You can unpublish a design from your account at any time.

What is in the Dataset Repo?

Sample datasets that include data, not just schemas: several hundred generated sets with foreign keys that resolve, statuses that match their timestamps and realistic number distributions. Each set downloads as CSV, JSON, SQL for four dialects, a Prisma seed or a Django fixture.

What is the Database Editor?

The Database Editor is a schema designer that runs in your browser. Write DBML on the left and the entity-relationship diagram updates on the right, or drag tables on the diagram and the code updates. It imports SQL from MySQL, PostgreSQL and SQL Server, and exports SQL, Prisma, Django models, a data dictionary, PNG, SVG and PDF.

Do I need an account to use the editor?

No. Without an account, diagrams are stored in your browser and never leave it, so they are available only in that browser. When you sign in, diagrams are stored in your account and sync across devices.

Do I need an account to download database samples?

No. Every schema and every dataset downloads without signing in.

How is my personal data handled?

The Privacy Policy lists what is collected and why. In short: browsing needs no account, and an account stores an email address, a password hash and the diagrams you save.
