Our Services

Database Architecture Services

From ground-up schema design to complex distributed system migrations — we cover every layer of your data stack.

Schema Design & Data Modeling

Normalized and denormalized schema design, ER diagrams, entity relationships, data type selection, indexing strategies, and documentation for long-term maintainability.

Scalability & Sharding

Horizontal and vertical scaling strategies, database sharding, partitioning, and read-replica architectures to handle millions of concurrent users without degradation.

Caching Architecture

Multi-layer caching with Redis and Memcached — write-through, write-behind, cache-aside patterns, cache invalidation strategies, and TTL tuning for sub-millisecond reads.

Replication & High Availability

Primary-replica replication, multi-region failover, automated backup strategies, point-in-time recovery (PITR), and zero-downtime deployment pipelines.

Database Migration

Zero-downtime migrations between engines (MySQL → PostgreSQL, MongoDB → CockroachDB), schema versioning with Flyway or Liquibase, and rollback planning.

Query Optimization & Tuning

EXPLAIN ANALYZE audits, slow-query profiling, composite index design, materialized views, N+1 elimination, and connection pooling with PgBouncer or ProxySQL.

Use Cases

Built for Every Data Challenge

Whether you're storing user profiles or processing billions of time-series events, we architect the right database for the job.

SaaS Multi-Tenancy

Schema-per-tenant or row-level isolation patterns — data segregation without sacrificing query performance.

Financial Transactions

ACID-compliant schemas, double-entry ledger design, distributed transactions, and audit trail tables.

Real-Time Analytics

ClickHouse or TimescaleDB for time-series data, OLAP query optimization, and streaming ingestion pipelines.

Mobile App Backends

Offline-first sync architectures, conflict resolution, partial indexes, and hot-path caching for mobile-scale workloads.

Healthcare Records

HIPAA-compliant designs with field-level encryption, access logging, and FHIR-compatible schema structures.

E-Commerce Catalogs

Product variant models, inventory tracking, flash-sale concurrency controls, and search-optimised Elasticsearch sync.

Social Graphs

Graph-aware relational schemas or native graph DBs (Neo4j) for follower feeds, recommendations, and relationship queries.

Geospatial & IoT

PostGIS for geospatial queries, time-series partitioning for sensor data, and streaming write pipelines for high-frequency IoT events.

Why It Matters

Architecture That Pays Off

A well-designed database is invisible. A poorly-designed one breaks at the worst possible moment. Here's what we build in from day one.

ACID Guarantees by Default

Transactions designed to be atomic, consistent, isolated, and durable — no data loss, no phantom reads, no split-brain corruption.

Index-First Design

We profile your query patterns before writing a single CREATE TABLE — ensuring every hot path hits an index, not a full table scan.

Cloud-Native & Managed

AWS RDS, Aurora, Google Cloud SQL, Neon, PlanetScale — we choose the managed service that fits your team's ops maturity and budget.

Security-First Schemas

Role-based access control, row-level security in PostgreSQL, field encryption, and audit logging baked in from the initial schema design.

Why Appther

Database Architects, Not Just DBAs

There's a difference between someone who can write SQL and someone who can architect a system that handles 10B records without breaking a sweat.

01

Query-Pattern-First Design

We start with your most critical read/write queries, not with generic best practices. Every index, partition, and schema decision is driven by real access patterns from your application.

02

Production-Proven at Scale

Our architects have designed databases handling billions of records, 100K+ concurrent connections, and multi-region distributed setups — across fintech, healthcare, and high-growth SaaS.

03

Zero-Downtime Migrations

Schema changes on live systems are high-risk. We use expand-contract patterns, online DDL, and shadow table migrations to ship changes with no service interruptions.

04

Full Polyglot Coverage

SQL, NoSQL, NewSQL, time-series, graph, vector — we know when to use each. We don't force a hammer on every nail; we pick the database that matches your data model.

05

Architecture Documentation

Every engagement ends with complete ERDs, runbooks, index rationale docs, and migration playbooks so your team owns the system long after we're done.

06

Ongoing Performance Reviews

We offer quarterly database health checks — reviewing slow query logs, bloat statistics, index usage, and lock contention to keep your system optimal as your data grows.

Our Process

From Requirements to Production-Ready

A structured 5-step process that eliminates guesswork and delivers a battle-tested database architecture in weeks, not months.

1

Discovery

Map your data entities, volume projections, access patterns, and compliance requirements (GDPR, HIPAA, PCI-DSS).

2

Schema Design

Design normalized schemas, ERDs, data types, constraints, and relationship models — reviewed with your dev team.

3

Indexing & Tuning

Define composite indexes, partial indexes, full-text indexes, and connection pool settings based on load simulations.

4

HA & Scaling Setup

Configure primary-replica replication, automated failover, read scaling, and backup / PITR with RTO targets.

5

Handover

Full documentation, runbooks, migration scripts, and a live walkthrough session with your engineering team.

FAQ

Common Questions

Which databases do you specialise in?
We work across PostgreSQL, MySQL/MariaDB, MongoDB, Redis, Elasticsearch, ClickHouse, CockroachDB, TimescaleDB, Apache Cassandra, DynamoDB, and managed cloud services like AWS Aurora, Google Cloud SQL, and Azure Cosmos DB. We select the right engine for your specific workload, not the most familiar one.
Can you help migrate our existing database without downtime?
Yes. We use expand-contract patterns, online DDL (pg_repack, pt-online-schema-change), and dual-write strategies to migrate schemas and data with zero downtime. We also handle cross-engine migrations (e.g. MySQL → PostgreSQL) using tools like pgloader or custom ETL pipelines with cutover windows under 60 seconds.
Our app is already live. Can you optimise an existing database?
Absolutely. We start with a comprehensive audit — EXPLAIN ANALYZE on slow queries, pg_stat_statements analysis, index bloat reports, N+1 detection, and lock contention profiling. We then deliver a prioritised optimisation plan with estimated impact for each change. Many clients see 90%+ query time reductions within the first sprint.
Should we use SQL or NoSQL for our app?
It depends on your data shape and query patterns. Relational data with complex joins and strict consistency → PostgreSQL. Flexible document structures with high write throughput → MongoDB. Ultra-fast caching or session storage → Redis. Analytical time-series → ClickHouse or TimescaleDB. We'll recommend the right fit after a short discovery call.
How do you handle database security and compliance?
We implement row-level security (RLS) in PostgreSQL, field-level encryption for PII, role-based access control (RBAC), audit logging, and network isolation (VPC, private subnets). For regulated industries (healthcare, fintech) we align schemas with HIPAA, PCI-DSS, and GDPR requirements from the outset.
What is your typical engagement timeline?
A green-field schema design engagement typically takes 2–4 weeks from discovery to production-ready setup. Complex migrations or architecture redesigns for large existing systems range from 4–12 weeks. We provide a detailed project plan with milestones during the proposal phase.
