attachmentchange

Attachmentchange is a term used to describe the event or signal that an attachment associated with a parent entity has undergone a modification. It can refer to the creation, update, or deletion of an attachment in a wide range of software systems, including content management, email clients, issue trackers, and customer relationship management tools.

In practical terms, an attachment change typically conveys information about which parent record the attachment belongs to, the identity of the attachment, the type of change (added, updated, or removed), the time of the change, and who performed it. Additional metadata may be included, such as the attachment’s name, size, mime type, version, and any relevant previous or current state to support auditing and versioning.

Implementation approaches vary. In event-driven architectures, AttachmentChange can be emitted as a discrete event consumed by other services or components. In databases, change data capture or triggers may log attachment changes to an audit or activity table. Some systems also expose attachment change as part of a real-time notification or activity feed.

Common patterns associated with attachment changes include access control checks, update propagation to related views, and maintenance of audit trails for compliance. Related concepts include AttachmentAdded, AttachmentUpdated, and AttachmentRemoved, as well as general change data capture and versioning practices.
