## Database Sample

DatabaseSample tackles the blank-page problem in data modelling. Instead of opening an empty designer, you search a catalogue of 1,847 published database designs — each with an ER diagram, table and column details, and an automated review that flags missing keys, absent indexes and other structural problems. Nearly a thousand multi-table sample datasets are also available with intact foreign keys, shipping as CSV, JSON, SQL for four dialects, a Prisma seed or a Django fixture, all released under CC0 with no account required.

Around that library sits a working toolkit. The DBML text editor renders a diagram as you type, the SQL playground runs queries in PostgreSQL or SQLite directly in the browser and shows the query plan, and share links bundle the schema, query and result into one reproducible URL. Field generators produce valid UUIDs, localised names, non-uniform numbers and test card data, while SQL dialect converters translate DDL between MySQL, PostgreSQL and SQL Server and spell out the semantic differences.

The AI side is the AI Generator and Dataset Studio. Describe the dataset you need and the model proposes a schema; the Free plan lets you run three designs a day and download a 50-row sample of every table, while Pro and Team plans raise limits, unlock complete datasets and private downloads, and add a stronger model inside the editor. Team workspaces add roles, comments and review requests, and a GitHub Action can review pull requests that change a shared schema.

**Pricing & Plans:** Freemium. All published database designs and datasets are free to download with no account. Dataset Studio generation starts free (50-row samples, 3 designs/day); Pro is $19/month for complete datasets and 25 designs/day; Team is $15 per user per month ($45/month for 3 seats) with shared workspaces; Education is free for verified school email addresses. Yearly billing costs ten months' price; Team is 50% off for verified educators.

- **1,847 database design catalogue:** Browse ready-made schemas by subject, each with an ER diagram, full column details and an automated design review that calls out missing keys and indexes.
- **AI schema generator and Dataset Studio:** Describe the data you need in plain English, compare generated designs, and download generated rows with working foreign keys in CSV, JSON, SQL, Prisma or Django formats.
- **In-browser DBML editor and SQL playground:** Write schema as DBML text and watch the diagram update live, then query generated rows in PostgreSQL or SQLite, inspect the query plan and share the whole thing as one reproducible link.
- **997 multi-table sample datasets under CC0:** Deterministically generated datasets with valid foreign keys, available in eight download formats with no account, no attribution and no restrictions.
- **SQL dialect converters and field generators:** Translate DDL between MySQL, PostgreSQL and SQL Server with differences called out, and generate UUIDs, localised names, skewed numeric distributions and standard test card numbers column by column.

**Strengths:** The design catalogue, sample datasets and download formats are free with no account, making it easy to evaluate before paying anything; Sample data is genuinely relational — foreign keys stay intact across tables, so it loads and queries like real data; Tooling is unusually complete for one site: catalogue, editor, diagram, SQL playground, converters, generators and AI design in one place; Transparent, published pricing with a free education tier and yearly billing equal to ten months

**Limitations:** Generated Studio results expire after 30 days on every plan, including paid ones, so output must be downloaded to be kept; The free tier is deliberately narrow — 50-row samples, three AI designs a day and 20 editor AI requests per month; Credit-style daily limits mean large modelling sessions on the Free plan require waiting for the next day

## Datascale

Datascale describes itself as "Cursor meets Miro for databases" — a visual canvas where you design, document and discuss data models, with an AI copilot embedded rather than bolted on. The core trick is reverse engineering: point it at DDL, CTAS (CREATE TABLE AS SELECT), views and INSERT INTO statements and it draws out the primary and foreign keys, including implicit joins where no declared keys exist. That makes it useful for teams inheriting a warehouse they did not build.

Beyond visualization, Datascale is positioned as a writing and thinking surface. You can drag-select nodes or tables and chat with the AI about them without leaving the board, ask it to expand a rough idea into a system design or analytics workflow, turn notes into polished design docs and PRDs, and get feedback on architecture trade-offs such as normalization versus denormalization. Data lineage and downstream impact tracing help you see what a change would affect before you make it.

Boards can be made public and embedded elsewhere, which supports sharing architecture with stakeholders or writing public documentation. Pricing is per user with a 7-day free trial that does not require a credit card. The team behind it describes itself as engineers building tools for other engineers, and there are named customer references from analytics consultancies.

**Pricing & Plans:** Per-user subscription with a 7-day free trial and no credit card required. Monthly is $12 per user per month; annual billing drops it to $8 per user per month. Both tiers include unlimited team members, unlimited boards and wikis, data lineage and ER diagrams, the AI Copilot and shared AI conversations. An enterprise/education discussion path is also referenced via a sales contact.

- **SQL reverse engineering:** Reads DDL, CTAS, views and INSERT INTO statements to rebuild your data architecture without migrations or framework changes.
- **Implicit join detection:** Surfaces primary and foreign key relationships even when no keys are declared, revealing the true structure of your data.
- **On-canvas AI copilot:** Drag-select nodes and tables, then ask questions, refactor models or co-design in context without switching tools.
- **Data lineage and impact analysis:** Maps dependencies and cross-table relationships grounded in your actual SQL so you can trace downstream effects of a change.
- **Docs, wikis and flowcharts in one place:** Combine diagrams, notes and flowcharts on a single canvas and turn rough ideas into design docs, PRDs and data specs.

**Strengths:** Rebuilds lineage and ER diagrams from SQL you already have, with no migrations; Detects implicit joins that tools relying on declared keys would miss; AI chat works directly on selected canvas nodes rather than in a separate window; Boards can be published and embedded, which helps with stakeholder communication

**Limitations:** Focused on SQL-based stacks; it is not a general-purpose diagramming suite; Smaller product and team than established BI catalog vendors, so governance features are lighter; The public pricing FAQ entries appear partially unfinished on the site
