# Database naming

## TL;DR

For data types: **PascalCase**

For data fields: **camelCase** 

For option sets: **SCREAMING\_SNAKE\_CASE** 

For option set fields:

* Use regular texts when the field needs to be displayed to end-users.
* Use rules like data fields for regular fields.
* Use **kebab-case** if the `Display` field is used for URL param.
