Electronic signatures are designed to help your organization comply with the FDA Code of Federal Regulations (CFR) Title 21 Part 11.

Electronic signatures provide the following data validation mechanisms:

  • Electronic signatures link the data to a reason for signing, the name of the signatory, and the date/time of the signature.
  • Electronic signatures are linked to a unique and unrepeatable id number.
  • Signatories must authenticate themselves with a username and password before signing.
Signing data resembles exporting a data grid, except, when data is signed, the signatory is presented with a pop-up dialog where a reason for signing can be specified. Only the rows in a given data grid that have been selected will be signed.

Upon signing, an Excel document of the signed data is created and added to the database as a record in the Signed Snapshot table. The Signed Snapshot table is available to administrators in the Query Browser in the compliance schema. You can add the Signed Snapshot web part to a page to allow users to download signed documents. The record includes the following information:

  • the Excel document (i.e., the signed data) is included as an attachment to the record
  • the source schema of the signed document
  • the source query of the signed document
  • the number of rows in the document
  • the file size of the document
  • the reason for signing the document
  • the signatory
  • the date of signing
