Oracle Fusion Has the Data Your Analytics Need.
Getting It Into BigQuery Without Breaking Production Is the Hard Part.Oracle Fusion Finance, HCM, and SCM contain the most operationally accurate enterprise data in the organisation. Getting it into BigQuery for analytics and AI requires either slow batch exports that are always stale, or a change data capture pipeline that streams commits from Oracle in real time. Batch exports are not analytics-ready data. CDC pipelines are.Symhas designs and deploys Oracle GoldenGate CDC pipelines streaming transactional changes from Oracle Fusion into BigQuery — real-time operational data available in BigQuery within minutes of commit, with no impact on Oracle Fusion production performance, and dbt transforming the raw CDC stream into analytics-ready datasets.

Oracle GoldenGate CDC PipelineGoldenGate · Log mining · CDC · Redo log · Capture · Replicat
Oracle GoldenGate captures transactional changes from the Oracle Fusion redo log — log-based CDC reading committed transactions without querying production tables, Extract process capturing changes, Replicat delivering them to the target, and GoldenGate Microservices providing REST-based monitoring and management.
GoldenGate Extract — log-based capture from Oracle Fusion redo log, zero production table scanning
GoldenGate Replicat — delivery of captured changes to Cloud Pub/Sub or BigQuery
Trail file management — local and remote trail files with compression and encryption in transit
DDL capture — schema change events captured and propagated alongside DML changes
GoldenGate Microservices — REST API-based management, monitoring, and alerting for the pipeline
Oracle Fusion transactional data in BigQuery within 5 minutes of commit — with zero production performance impact
GoldenGate to BigQuery via DataflowPub/Sub · Dataflow · BigQuery · Schema evolution · Exactly-once
GoldenGate Replicat delivers change events to Cloud Pub/Sub, with a Dataflow streaming pipeline consuming events, applying schema mapping, and writing to BigQuery using exactly-once semantics — handling schema evolution, deletes, and updates as BigQuery upserts.
Pub/Sub delivery — GoldenGate Replicat writing change events to Pub/Sub topic
Dataflow streaming pipeline — schema mapping, type conversion, and BigQuery write
Exactly-once to BigQuery — Dataflow streaming inserts with deduplication key
BigQuery MERGE handling — UPDATE and DELETE events applied as BigQuery MERGE operations
Schema evolution — new Oracle columns detected and propagated to BigQuery schema automatically
Every Oracle Fusion transaction faithfully represented in BigQuery — inserts, updates, and deletes, no data loss
Oracle Fusion Module CoverageFinance · HCM · SCM · GL · AP · AR · Payroll · Inventory
Symhas Oracle Fusion CDC coverage spans Finance (GL, AP, AR, Fixed Assets), HCM (Core HR, Payroll, Absence), and SCM (Inventory, Purchase Orders, Sales Orders) — the tables and entities most useful for analytics and AI use cases, with Oracle-to-BigQuery data model mapping documented.
Oracle Financials — GL journals, AP invoices, AR transactions, Fixed Assets, Cash Management
Oracle HCM — Worker, Assignment, Payroll, Absence, Compensation, and Performance data
Oracle SCM — Inventory transactions, Purchase Orders, Sales Orders, and Receipts
Cross-module analytics — Journal-to-Worker cost allocation, Order-to-Cash, Procure-to-Pay
Oracle Fusion REST API — supplemental data from Fusion REST where CDC is not applicable
All Oracle Fusion operational data available in BigQuery — Finance, HCM, and SCM in one analytics platform
dbt Transformation on CDC Datadbt · Incremental models · SCD Type 2 · Slowly changing · Analytics-ready
dbt incremental models transforming the raw GoldenGate CDC stream in BigQuery — SCD Type 2 history tables preserving prior states for point-in-time analysis, business logic applied on top of the raw operational data, and gold-layer marts producing analytics-ready tables for Looker and Vertex AI.
dbt incremental models — processing only new CDC records on each run, not full table refresh
SCD Type 2 — slowly changing dimension tables preserving full history of Oracle Fusion entity changes
Business logic layer — Oracle-specific data model abstracted into business-friendly dimensions and facts
Gold layer marts — aggregated tables for Finance P&L, HCM headcount, SCM inventory position
dbt tests — uniqueness, referential integrity, and business rule validation on every CDC pipeline run
Raw Oracle CDC data transformed into analytics-ready BigQuery datasets — Finance, HCM, and SCM in consistent business terms

Retail · Oracle ERP to GCP Integration500+ Location Retailer.
Oracle SCM in BigQuery. Real-Time Inventory. 33% Forecast Accuracy Gain.

The national retailer was running Oracle Fusion SCM for inventory and purchase order management but exporting data to a reporting database via nightly batch extracts — 14-hour-old inventory data at the start of every business day, with no ability to run intraday demand sensing.

Symhas deployed Oracle GoldenGate CDC connecting Oracle Fusion SCM to BigQuery via Dataflow — inventory transactions, purchase order receipts, and sales order confirmations available in BigQuery within 5 minutes of commit. Vertex AI demand forecasting models trained on real-time inventory positions, enabling intraday replenishment signals.

What was delivered

Oracle GoldenGate CDC to BigQuery — Retail Production

→GoldenGate Extract — log-based capture from Oracle Fusion SCM 12.2, zero production table scanning
→Pub/Sub — GoldenGate Replicat delivering change events, 180K inventory events per hour at peak
→Dataflow pipeline — schema mapping for 47 Oracle SCM tables, exactly-once BigQuery writes
→BigQuery MERGE — UPDATE and DELETE events applied as MERGE operations, audit history preserved
→dbt incremental models — 23 models processing CDC stream, SCD Type 2 for inventory location history
→Lag monitoring — GoldenGate Microservices lag alert configured, PagerDuty notification if lag exceeds 10 minutes

“We went from 14-hour-old inventory data to 5-minute-fresh data in BigQuery. The forecasting models that used to be trained on yesterday morning now train on what happened an hour ago. That changes the replenishment conversation entirely.”

Why Symhas
GCP Expertise Built from Production Deployments.
Log-Based CDC, Not Table PollingTable polling extracts put query load on Oracle Fusion and return stale data. Symhas implements GoldenGate log-based CDC — reading from the redo log without touching production tables — zero Oracle Fusion performance impact.
Table Selection Based on Analytics Use Cases FirstCapturing every Oracle Fusion table creates an unmanageable CDC stream with most data never queried. Symhas starts from the analytics and AI use cases and works backwards to the tables required — focused scope, faster delivery, lower cost.
SCD Type 2 Built Into the dbt LayerRaw CDC streams without slowly changing dimension handling lose the history that makes time-series analysis possible. Symhas builds SCD Type 2 models in dbt for all key Oracle Fusion entities — full change history preserved from go-live.
Exactly-Once Semantics on Every CDC PipelineGoldenGate pipelines that restart after failure can deliver duplicate events. Symhas configures exactly-once delivery on the Dataflow pipeline — deduplication by change event key, duplicates structurally prevented.
Lag Monitoring Configured Before Go-LiveCDC lag that grows silently invalidates every analytics SLA built on top of it. Symhas configures GoldenGate lag monitoring and alerting before go-live — the pipeline team knows about lag before the analytics team notices stale data.
Data Engineering Team Certified on GoldenGate OperationsBy handover your data engineering team monitors GoldenGate lag, adds new source tables, and manages the Dataflow pipeline independently. Certified on GoldenGate Microservices before Symhas steps back.
