To expose custom database tables to Drupal Views, implement `hook_views_data()` in your module to define table schemas, relationships, and fields. This makes your non-entity data discoverable and filterable within the Views UI.

Entity integration with Drupal Views works automatically by using entity annotations or attributes to expose base fields. This allows site builders to create Views listings, filter data, and sort content entities without manual data definitions.

You create custom Views plugins for fields, filters, and sorts by developing specific plugin classes that extend Views base functionality. This allows for advanced data manipulation and custom display logic when built-in Views features are insufficient.

Yes, you can alter existing Views data definitions from other modules by implementing `hook_views_data_alter()`. This allows you to modify, override, or extend how external modules expose their database tables and fields to the Views UI.

You need custom Views plugins when built-in Views functionality cannot handle your advanced data manipulation or display requirements. Custom field, filter, sort, and argument plugins provide the necessary logic for complex custom entity integration.

The best way to integrate a custom content entity with Views is by using entity annotations or attributes to automatically expose base fields. This enables site builders to filter by date and sort by title directly within the Views UI.
