# BackendName


A supported database backend, as a string literal.


`BackendName: TypeAlias = Literal[``"postgresql", `<span class="st">`"mysql"``, ``"sqlite"``]`</span>


Using a `Literal` type rather than a plain `str` lets type checkers catch misspelled backend names at analysis time instead of at runtime.
