Jourier's Data Hub sits between IBM Db2 and Sigma. IBM Db2 data flows into the layer continuously (real-time CDC where supported, webhooks and polling otherwise), gets modeled to your business, and surfaces in Sigma as a clean dataset your team can build operational reporting, KPI dashboards, and data-quality monitoring on top of.

For teams that want more than a packaged BI experience, the same Data Hub feeds a bespoke data application coded in React and TypeScript, owned by your team. Sigma runs alongside the bespoke application or in front of it, depending on what each part of the business needs.

IBM Db2 is a backend store, not an analytics surface — so the question is shape, not transport. Jourier's modeling layer translates operational schemas into analytical entities (customers, transactions, periods) without disturbing the source application's contract with the database.

On Sigma, IBM Db2 data is queried directly from the warehouse with a spreadsheet-style interface that business users actually understand. Jourier prepares the IBM Db2 modeled layer in the warehouse for that interaction — clean column names, well-typed fields, foreign keys defined — so Sigma's analyst experience starts from a usable foundation.

Result: Sigma reports on IBM Db2 read from a layer engineered for operational reporting, with definitions consistent across reports and across the rest of the operational stack.

Sigma is a strong choice for teams that want a packaged dashboard experience on top of IBM Db2. For workflows Sigma doesn't cover (custom UI, write-back to IBM Db2, role-specific tools), Jourier builds a bespoke React application on the same Data Hub. Both can live alongside each other.

Can I connect IBM Db2 to Sigma through Jourier?

Yes. Jourier builds a bespoke IBM Db2 → Sigma integration through the Data Hub layer. IBM Db2 data is modeled, kept current, and exposed to Sigma as a clean dataset your team can build operational reporting on top of. The same modeled tables can feed coded React applications and AI assistants alongside Sigma, so the numbers stay consistent regardless of which surface a stakeholder uses. No connector licence fees if you self-host the data layer.

Is the IBM Db2 → Sigma sync real-time?

Where IBM Db2 supports change-data-capture, yes — updates surface in Sigma within seconds. Where it doesn't, scheduled polling and webhooks keep the layer current at the cadence the business actually needs (5 minutes for operational dashboards, hourly for finance, daily for archival). Time to first sync is typically instant to one day. The Data Hub holds the canonical state, so reports and dashboards never read directly from IBM Db2's API.

What does a IBM Db2 → Sigma engagement cost?

Bespoke project, scoped to the IBM Db2 workflows that matter and the Sigma reports your team actually uses. Pricing is project-based, not subscription-based — a fixed-fee build for the data layer + the Sigma dataset, then optional managed-services if you want Jourier to run it. No per-seat licences from Jourier, no platform fees if you self-host. Sigma licences are paid directly to Sigma Computing; we never mark them up.

Who owns the IBM Db2 → Sigma integration code?

You do. Pipelines, data model, semantic layer config, Sigma dataset definitions, documentation: all yours. Self-host or have us host. Hand it to another vendor whenever you want, or take it over with your own team. Jourier delivers everything as code in a repository you own, with runbooks for how to operate it. No lock-in, no per-engagement licence.

Can I move off Sigma later but keep the IBM Db2 integration?

Yes. The Data Hub feeds Sigma today, and the same layer feeds open-source dashboards (Apache Superset, Metabase, Grafana), a bespoke React application, or a different vendor BI tool tomorrow. The IBM Db2 side of the integration — the pipeline, the modeling, the access controls — is unchanged when you switch front-ends. Most of our customers keep multiple consumers running in parallel during a transition window.

How long does a IBM Db2 → Sigma engagement take?

First sync of IBM Db2 data is typically instant to one day. A scoped engagement covering IBM Db2 plus the Sigma reports that matter usually runs four to eight weeks. Bigger transformations are split into phases, each shipping value before the next begins. Jourier handles the IBM Db2 pipeline, the modeling, the Sigma dataset, and the access controls. Your team validates the reports and trains the analysts.

Can existing Sigma reports built on IBM Db2 be migrated to the new model?

Usually yes. Most existing Sigma reports become thin wrappers over the new modeled tables — the report logic stays, the data source switches from a direct IBM Db2 connector to the Data Hub. Jourier audits the existing Sigma workspace, identifies what's worth keeping, and rebuilds report-by-report against the new model. Reports that were workarounds for IBM Db2's data shape get simplified or retired.

How do permissions work for Sigma pulling IBM Db2 data?

Permissions live in the Data Hub, not in Sigma. Each Sigma user authenticates against your identity provider; the dataset that Sigma reads is filtered server-side based on the user's role, region, or department. Sigma's own row-level security still works on top of this. Result: a sales rep in Helsinki and one in New York hitting the same Sigma dashboard see different rows automatically, with the rule defined once in the layer.
