Why teams connect MariaDB and Oracle Fusion Cloud HCM

Put your workforce data where your apps can reach it: MariaDB and Oracle Fusion Cloud HCM share the same people, positions, and org structure in real time.

Oracle Fusion Cloud HCM is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. MariaDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Departments (Organizations), Locations, Grades and Salaries, Absences (workerAbsenceEntries) in Oracle Fusion Cloud HCM need to exist as queryable Views, Columns, Primary and Unique Keys, System-Versioned Tables in MariaDB before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Views, Columns, Primary and Unique Keys, System-Versioned Tables in MariaDB with Departments (Organizations), Locations, Grades and Salaries, Absences (workerAbsenceEntries) in Oracle Fusion Cloud HCM field by field, in real time. You decide which system owns which fields — Oracle Fusion Cloud HCM typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Replicate ERP or billing master data into MariaDB databases that power customer-facing applications
  • 02 Feed a warehouse continuously from MariaDB using binlog-based capture instead of scheduled dumps
  • 03 Keep Positions and Departments aligned between Oracle HCM and a finance/ERP system so cost centers and reporting structures match.
  • 04 Sync Absences (workerAbsenceEntries) into a scheduling or workforce-management database for coverage planning.

Common sync patterns

Reporting and analytics on current data

Departments (Organizations), Locations, Grades and Salaries, Absences (workerAbsenceEntries) replicate into MariaDB where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Oracle Fusion Cloud HCM stay consistent in MariaDB, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in MariaDB write onto the matching record in Oracle Fusion Cloud HCM where those fields are writable, keeping the people system enriched.

What you can sync between MariaDB and Oracle Fusion Cloud HCM

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

MariaDB objects Oracle Fusion Cloud HCM objects How this pairing syncs
Stored Procedures Server-side logic that can post-process synced rows. Absences (workerAbsenceEntries) Time-off and leave entries; synced into scheduling or workforce-management databases for coverage planning. Stored Procedures is specific to MariaDB and Absences (workerAbsenceEntries) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. Workers (publicWorkers) Person master with personNumber, names, national IDs, and work relationships; synced two-way via the /workers resource, which replaced the desupported /emps resource. Databases (Schemas) is specific to MariaDB and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Tables The primary sync target; rows map to records in connected systems. Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Tables is specific to MariaDB and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Views Read-side projections used as outbound sync sources. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Views is specific to MariaDB and Jobs to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Columns Field-level mapping targets with engine-typed values. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Columns is specific to MariaDB and Positions to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Primary and Unique Keys Match keys for idempotent upserts. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Primary and Unique Keys is specific to MariaDB and Departments (Organizations) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between MariaDB and Oracle Fusion Cloud HCM

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

MariaDB Oracle Fusion Cloud HCM Sub-second propagation

DetectionChanges in MariaDB are captured at the source via change data capture — no polling loop against its API. Database triggers — Stacksync creates deterministic triggers for internal logging and syncing.

DeliveryEach detected change is written to Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Oracle Fusion Cloud HCM MariaDB Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

DeliveryEach detected change is applied to MariaDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • MariaDB: No API rate limits; throughput is bounded by connection limits and server resources.
  • Oracle Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
