Discipline Specification // DATABASE DESIGN MIGRATIONS

Database Design & Migration Services

Bad schema decisions made at the start of a project compound quickly — they show up as N+1 queries, as migrations that take 20 minutes to run in production, as data inconsistency that's hard to debug, and eventually as a rewrite. SynS Infrastructure approaches database work the same way it approaches API design: with a written contract upfront, explicit trade-offs documented, and an output that can be maintained by whoever comes next.

DELIVERY COMMITMENT

Continuous staging previews from Sprint 1 with clean architectural handovers.

Target Alignment

Who this is for

  • 01A team moving from prototype to production who needs their schema reviewed before real users depend on it.
  • 02An engineering team that needs to migrate from MongoDB to Postgres, or between Postgres versions/providers, without downtime.
  • 03A startup that grew its database organically and now has performance or consistency problems to untangle.
Deliverable Scope

What's included

  • ✓Schema design from scratch or review of an existing schema — with documented trade-offs
  • ✓Normalisation and denormalisation decisions made explicitly, not by accident
  • ✓Index strategy based on the actual query patterns, not guesswork
  • ✓Migration scripts with rollback paths — tested against a staging copy before touching production
  • ✓Row Level Security (RLS) policy design for Supabase/Postgres projects
  • ✓Performance review: slow query identification, EXPLAIN ANALYZE walkthroughs, and fixes
Engineering Stack

Stack & tooling architecture for Database Design & Migration Services.

Why we choose each component in the production runtime.

Postgres

Primary choice — mature, reliable, excellent support for RLS, full-text search, and JSON

Supabase

Managed Postgres with Auth, realtime, and a good migration workflow

MongoDB

Where document-oriented storage genuinely fits the access patterns

MySQL

For projects where the hosting environment or team preference requires it

Drizzle / Prisma

Type-safe ORM layer where it adds value — explicit about when raw SQL is cleaner

Engagement Protocol

How this discipline executes.

01

Scope & Architecture

Define exactly what gets built, what doesn't, and milestone criteria — in writing, before work starts.

02

Iterative Staging

Weekly written updates with staging deployments from the first sprint. Test features as they are built.

03

Handover & Ownership

100% repository, credentials, and documentation handed over. Retainers available for ongoing evolution.

Technical Clarifications

Questions & answers for this discipline.

Can you migrate our database without downtime?+

Zero-downtime migrations are possible for most schema changes using expand/contract patterns — adding columns before dropping old ones, backfilling in batches. We'll be explicit in the scoping phase about which changes require a maintenance window.

Do you work with cloud databases or only self-hosted?+

Managed services (Supabase, RDS, Neon, PlanetScale) and self-hosted. The choice depends on your team's ops capacity and the project's requirements.

Can you review our existing schema without doing the migration?+

Yes — a schema review is a standalone engagement. You'll get a written report with specific recommendations, not just a list of abstract best practices.

Do you handle data privacy and GDPR requirements?+

We'll flag where the schema has implications for data retention and deletion, and design RLS policies accordingly. For full legal compliance review, that's a job for a solicitor.
