Sqemo is an ERD tool built around one idea: physical names should be generated from your team's naming standard, not typed by hand.
You register a glossary (customer โ cust, number โ no) and naming rules (case style, delimiter, how to handle unknown words) first. Then you model at the logical level โ "Customer Number" โ and the physical column comes out cust_no, the same way for everyone, every time. Overrides are allowed but explicitly flagged, so they never spread silently. Because the correct name is computable, drift is detectable: an in-app linter flags deviations, and a CLI fails CI on violations (npx sqemo-mcp lint).
Key capabilities: โข Logical/physical model separation with stable links between the two โข SQL DDL import/export in seven dialects: MySQL, PostgreSQL, Oracle, SQL Server, SQLite, H2, CUBRID โข DBML import/export โ one round trip to move from dbdiagram โข Runs free in the browser with no sign-up; projects autosave locally and live in a plain .erd.json file you can commit โข MCP server (sqemo-mcp) with 33 tools โ AI agents read and edit your ERD while following your naming standard โข Team workspaces: shared standard, proposeโapprove queue for new glossary words, and a compliance view showing which ERDs drift from the standard

With this, I went for designing the db. I went to http://drawsql.app/ and created my first draft. Then exported the DDL and did a bit of back and forth with AI. This is the final draft of the database:. - Source: dev.to / 8 months ago
So I started designing the DB using this cool tool. The project has 2 tables, users and categories . The user can create many categories as he wants so the first approach I took was creating a third table, a union table to store user_id and category_id. With this solution the users are able to create x numbers of categories and we can see assign the category to the user. - Source: dev.to / over 1 year ago
Once you have generated the SQL code, you can convert it into a relational schema (the graphical table model) using DrawSQL. This tool offers:. - Source: dev.to / over 1 year ago
DrawSQL makes it easy for teams to collaborate on creating and maintaining schema diagrams. With a single source of truth, there's no need for manually syncing diagram files between different developers and offline tools anymore. Source: about 3 years ago
To be honest, since you are just getting started, I think you should reconsider simplifying this app to begin with. Built something easier and get some more experience before jumping in the ocean. Maybe start by focusing only on the parent company and sub-companies. However, I strongly recommend you to try and make a diagram of your database with relations and columns as it can you a lot of time. I personally use... Source: about 3 years ago
