Common Mistakes to Avoid

Not Validating Data Before Saving

Failing to validate data can lead to incorrect information being saved, causing issues later. Always implement validation checks to ensure data integrity before saving documents.

Overwriting Existing Documents Without Backup

Overwriting documents without creating backups can result in data loss. Always create a backup before making significant updates to existing documents to prevent irreversible mistakes.

Neglecting to Update Related Documents

When updating a document, neglecting to update related documents can lead to inconsistencies. Ensure that all interconnected documents are reviewed and updated accordingly to maintain coherence.

Deleting Documents Without Reviewing Dependencies

Deleting documents without understanding their dependencies can disrupt workflows. Always review how a document is linked to others before deletion to avoid breaking processes.
