Content Documents


ERD for Content Documents

When a Content Document is created, a content version record is created.  Each update gets stored as a version and the content document LatestPublishedVersionId is updated. When linking a content document with a record, a ContentDocumentLink is created.  A Content Document can be associated with multiple records in the system.

ContentNotes are only notes which are stored as well in the ContentDocument object.  You can filter ContentNotes using FileType = 'SNOTE' in the ContentDocument object.

"Implementation restriction: ContentDocumentLink requires a filter by a single Id on ContentDocumentId or LinkedEntityId using the equals operator or multiple Id's using the IN operator."
