## How to configure To configure the generator, toggle the **Consistency** setting to indicate whether to make the generator consistent. By default, the generator is not consistent. If you enable consistency, then by default the generator is self-consistent. To make the generator consistent with another column, from **Consistent to**, select the column. When the generator is consistent with itself, then a given value in the source database is mapped to the same value in the destination database. For example, Host123 in the source database always produces MyHostABC in the destination database. When the generator is consistent with another column, then a given source value in the other column results in the same host name value in the destination database. For example, a host name column is consistent with a department column. Every instance of Sales in the source data is given the same host name in the destination database. If [Structural data encryption](https://docs.tonic.ai/app/generation/generators-assign-config/generators-data-encryption-config) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position.
