Overview

IBM Db2 and AS/400 (IBM i) systems remain integration sources in manufacturing and finance clients—.NET services access them via ODBC or message bridges while operational stores stay on SQL Server or Azure for new Factory work.

Relational SQL Server on Azure remains the default for Factory and SaaS templates—paired with NHibernate or EF Core, migrations in CI, and backup policies that match enterprise SLAs.

Polyglot and client-mandated stores are supported with clear boundaries: integration schemas, migration tooling, and capacity planning so operational data never becomes an undocumented side channel.

Need search, cache, or warehouse tiers alongside transactional SQL? We design data paths that stay observable, recoverable, and aligned with your Azure landing zone.

Why we use it:

  • Read-only or replicated access where possible
  • Charset and CCSID mapping validated
  • Batch windows for heavy extracts
  • Clear ownership between integration and core teams
  • Migration and rollback discipline in Azure Pipelines
  • Encryption, redundancy, and residency matched to SLA
  • Clear ownership between platform SQL and integration stores
