 /**
  * Module to generate database related entries.
+ *
+ * ### Overview
+ *
+ * Traditional relational database tables have data organized in columns with specific types - [`column()`](https://next.fakerjs.dev/api/database.html#column), [`type()`](https://next.fakerjs.dev/api/database.html#type). The database usually has an [`engine()`](https://next.fakerjs.dev/api/database.html#engine) and a default [`collation()`](https://next.fakerjs.dev/api/database.html#collation) for sorting.
+ *
+ * For the NoSQL database MongoDB, [`mongodbObjectId()`](https://next.fakerjs.dev/api/database.html#mongodbobjectid) provides a random ID.
