• If you are a computer engineering or management information systems student, preparing a graduation project, or developing your own web/mobile application, the most basic step of the project is Database Relationship Diagram (ER Diagram / Tables and Foreign Keys) is to design. However, many database drawing sites on the market (e.g. Lucidchart, DrawSQL or dbdiagram) have a free version "You can draw up to 3 tables or 1 diagram, pay $15 per month to get SQL output" leaves students and developers stranded. Here is the shining star of the open source world drawDB (drawdb.app) allows you to draw unlimited database architecture in your browser without requiring any membership and convert it to ready-made SQL code with one click provides!

  Edit your tables with the mouse in the visual editor (users, orders, products etc.), you create one-to-many (1-N) relationships by dragging and dropping columns together; When you're done "Export SQL" MySQL, PostgreSQL, SQLite, MariaDB or MSSQL for all CREATE TABLE codes ready without any errors! Or vice versa: You have a complex .sql file to the site and convert it into a visual chart map in seconds!

• STEP BY STEP USE:

  1. From your browser https://www.drawdb.app/ and "Go to Editor" (Go to Editor) button (The workspace opens directly without leaving the registration or login screen).

  2. If you are trying it for the first time, select "Templates" tab and load a ready-made e-commerce, blog or financial database schema as an example, or "New Diagram".

  3. "Add Table" button you can enter the name and columns of your table (id, title, created_at etc.), data types (INT, VARCHAR, BOOLEAN) and Primary Key (PK) marks.

  4. Draw a line with the mouse from the column point of one table to the column of the other table in the drawing area on the right Foreign Key relationship.

  5. "File > Export" to view the architecture you have drawn SQL script (MySQL, PostgreSQL, SQLite, MSSQL) as PNG / PDF / Markdown or Mermaid format!

• REQUIREMENTS AND LIMITS: No membership, credit card or table/diagram count limits; It is completely free. Optimized for use in desktop browsers.

• PRIVACY AND SECURITY: According to the official open source architecture drawdb.app by default in your own browser's local database (IndexedDB / localStorage) is stored; it is not sent to a remote cloud server. In this way, you can design the table structure of your company or project without privacy concerns. Before clearing your browser cache, be sure to "File > Save as (.ddb)" or SQL/JSON.

• ADVANTAGES, DISADVANTAGES AND WHOM IT IS SUITABLE FOR:

  • Advantages: 100% free and open source, instant use without membership, both generating SQL from drawing and automatically drawing schema from existing SQL file (Reverse Engineering), PNG/PDF/Markdown/Mermaid output.

  • Disadvantages: The interface is in English and is a technical tool aimed directly at the software/database development discipline.

  • Who is it suitable for: Computer engineering, software and MIS students, backend/fullstack developers, data architects and senior thesis report preparers.

• BRIEF CONCLUSION: Instead of paying sites that impose table limits in your database assignments or application projects drawdb.app; visually draw your schema "Export SQL"!
