常见问题
Quick answers.
›What SQL dialects are supported?
The generator produces standard ANSI SQL compatible with PostgreSQL, MySQL, and SQLite. You can adjust specific data types in the text editor before exporting.
›How does it handle relationships?
The DSL identifies shared keys to automatically generate `FOREIGN KEY` constraints and appropriate join table structures for many-to-many relationships.
›Is my database schema saved anywhere?
No. All parsing and SQL generation occurs locally within your browser session. Your architectural designs are never transmitted to a server.
›Can I define indexes in the DSL?
Yes. You can flag specific columns as unique or indexed within the text definition, and the tool will generate the corresponding `CREATE INDEX` statements.
