Question 1

Should database names be snake_case or camelCase?

Accepted Answer

Lowercase snake_case is the safest choice. PostgreSQL folds unquoted identifiers to lowercase, so mixed-case names require quoting in every query. snake_case works without quoting on PostgreSQL, MySQL, SQL Server and SQLite.

Question 2

How long can a database name be?

Accepted Answer

PostgreSQL allows 63 bytes, MySQL and MariaDB allow 64 characters, and SQL Server allows 128 characters. For readability, keep names under 32 characters regardless of the limit.

Question 3

Can I use hyphens or spaces in a database name?

Accepted Answer

Only with quoting, which you will have to repeat in every query, script and connection string. Underscores need no quoting anywhere, so they are the safer separator.

Question 4

Are DbDen names guaranteed to be unique?

Accepted Answer

No. They are random starting-point suggestions. Always check the name is free on your own server and follows your database engine's identifier rules before using it.

Question 5

How should I name dev, staging and production databases?

Accepted Answer

Use one base name with an environment suffix: shop_dev, shop_staging, shop_prod. Keep the domain first and the environment last so the databases sort and group together.

Question 6

Does DbDen send my generated names anywhere?

Accepted Answer

No. Everything runs 100% in your browser with JavaScript. Nothing is sent to a server, nothing is stored, and there are no cookies or tracking.

Question	Answer
snake_case or camelCase?	Lowercase `snake_case`. PostgreSQL folds unquoted identifiers to lowercase, so mixed case forces quoting everywhere. snake_case needs no quoting on any major engine.
How long can a database name be?	PostgreSQL: 63 bytes. MySQL/MariaDB: 64 characters. SQL Server: 128 characters. Keep names under 32 characters for readability.
Hyphens or spaces?	Only with quoting in every query — avoid them. Underscores are the safe separator.
Can a name start with a digit?	Technically possible with quoting on some engines, but avoid it. Start with a letter.
Which words must I avoid?	SQL reserved words: `select`, `table`, `order`, `group`, `user`, `index`, `database`, `schema`, and hundreds more per engine.
How do I name environments?	One base + suffix: `shop_dev`, `shop_staging`, `shop_prod`. Domain first, environment last.
Are generated names unique?	No — they are starting-point suggestions. Always verify availability on your own server.
Can I use these names commercially?	Yes. They are random word combinations; just confirm the name is free and does not collide with an existing trademark in your context.
Is anything sent to a server?	No. The generator runs 100% in your browser. No signup, no cookies, no tracking.
Does it work offline?	After the first page load, the tool itself runs entirely offline since it needs no network calls.
