> [!tip] CDS models are database-agnostic
> CDS models are designed to be database-agnostic, allowing you to switch between different databases with minimal changes. The `--dialect` option helps you see how your models translate to different database-specific DDLs. \

Outdated

Note that expressions in CDS models are _not_ treated in a database-agnostic way. In other words, they are not rewritten
into database-specific equivalents; instead, they are carried over one-to-one into the DDL.
You therefore need to ensure that any expression you write in your CDS model works across all databases you use.
See also [Database-Specific Models](#database-specific-models).
