ApprovalAttachment

ApprovalAttachment is a data construct used in workflow and approval systems to associate one or more files or documents with a specific approval request or step. It serves as a bridge between the approval record and its supporting evidence, ensuring reviewers have access to relevant materials during the decision process and that an auditable trail is maintained.

Typically, an approval attachment includes identifiers for the approval item it relates to, a reference to the stored file, and metadata such as file name, mime type, size, and the uploader. In some implementations the attachment is stored as a separate file resource and the approval attachment holds a link rather than embedding the data.

Lifecycle: An attachment is added by a user or system process when evidence is provided. The approval status may be updated or delays introduced based on the attached documents. Attachments can be versioned or replaced, and may be flagged as required or optional. Deletion usually requires appropriate permissions and may persist in an audit log.

Usage scenarios: procurement approvals with vendor quotes, regulatory submissions with compliance documents, or change management where design documents are attached. It supports audit and compliance by keeping a trace of what documents influenced the approval decision.

Implementation considerations: access control, encryption, retention policies, searchability, and linkage to the approval lifecycle. In some platforms approval attachment is a built-in object; in others it is modeled as a junction or child entity in the data schema.
