Database Engineering

The deepest part of our practice.

Deep production database work across Oracle, PostgreSQL, SQL Server and the cloud-native platforms that have largely replaced them. This is where the fastest wins usually are: tuning a query is almost always cheaper than buying more hardware.

What we do

  • Logical & physical data modellingConceptual through physical models, normalisation and deliberate denormalisation, dimensional and Data Vault approaches where they fit.
  • Database design & developmentSchema design, constraints and referential integrity, stored procedures and packages, across Oracle, PostgreSQL, MySQL and SQL Server.
  • Performance tuningExecution plan analysis, index strategy, statistics management, partitioning and query rewrites.
  • High availability & recoveryReplication topology, failover design, backup strategy and tested recovery procedures with real recovery time objectives.
  • Migration & upgradeVersion upgrades and cross-platform migration with parallel validation and reconciliation before cutover.
  • Oracle Data Integrator developmentODI mappings, packages, load plans and knowledge module customisation, including remediation of inherited estates.

Who usually owns the budget

CTO, VP Engineering, or a Head of Platform whose database has become the bottleneck.

What triggers the purchase

  • Queries that used to take seconds now take minutes
  • An unsupported database version is becoming an audit finding
  • Nobody has tested whether the backups actually restore

Depth by platform

Six engines. One team that has actually run every one of them in production.

Not a line in a tech-stack list: each of these is a platform we have tuned, replicated, failed over and upgraded under a live workload.
