Where PostgreSQL fits
Related business records with explicit integrity, access and reporting rules.
When to choose another approach
Transactions do not guarantee freedom from operator mistakes, incorrect business logic or data loss. Backups and restore checks remain necessary.
Worked example and evidence
Fictional purchase order: store supplier, line items and approval together. Reject an invalid supplier reference and prevent requesters approving their own orders.
What you need to supply
Schema, sanitized records, permission matrix, current counts/totals and recovery needs.
What acceptance should demonstrate
Reconcile migrated counts, totals and sampled relationships. Check permissions and restore a backup before cutover.
Running costs and responsibilities
Assign database hosting, patches, storage growth, access review, backups and recovery.
Technical scope to confirm
Choose a backup strategy and recovery window for the deployed version and infrastructure.
A proposal should identify the systems and data, direction of sync, access feasibility, failure handling, named owners and included deliverables. Listing this technology does not imply a prebuilt connector, vendor partnership or included feature.
How will migration accuracy be accepted?
Agree reconciliation rules before moving data. Compare counts, financial totals, relationships and exceptions, then obtain approval from the business data owner.
