WHY THIS MATTERS

Data Notifications influence some of the most important operational and commercial aspects of market data management — including cost control, entitlement management, licensing alignment, and service continuity.

As notification volumes increase across exchanges and vendors, firms face growing pressure to ensure updates are reviewed, understood, and actioned efficiently.

Without the right level of automation and oversight:

• - Fee and licensing changes may be difficult to track at scale.
• - Operational teams spend significant time reviewing and validating updates.
• - Managing permissions and downstream impacts becomes increasingly resource-intensive.
• - Maintaining a clear audit trail across notifications and actions may become challenging over time.
• - Missed or delayed actions may result in service disruption, data outages, and operational risk.

THE OPERATIONAL CHALLENGE

The challenge is ensuring notifications are consistently captured, understood, validated, and actioned correctly.  For firms:

• - Notifications arrive continuously across multiple channels (LSEG, Bloomberg, etc).
• - Operational teams spend significant time reviewing and validating updates.
• - Notification changes often need to be tracked, governed, and linked to internal operational workflows and ITSM processes.

WHAT DN HUB DOES

DN Hub provides a structured operational framework for managing exchange and vendor Data Notifications — from receipt to validation, actioning, and audit.

The platform:

• - Ingests notifications across daily, weekly, quarterly, and ad hoc update cycles.
• - Centralises notifications into a searchable and trackable operational workflow.
• - Compares notification changes against entitlement and usage data.
• - Identifies affected users, applications, services, and permission groups.
• - Highlights operational, licensing, compliance, and cost impacts.
• - Supports operational workflows, approvals, and downstream ITSM processes.
• - Maintains a complete audit trail of notifications, actions, and operational history.

DN Hub helps firms improve visibility, reduce manual effort, and increase operational control across the Data Notification lifecycle by combining notification management, operational workflow, and auditability in a single platform.

Never Miss a Notification Update - Ensure notifications are consistently captured, tracked, and operationally managed across daily, weekly, quarterly, and ad-hoc update cycles.

Better Workflow Coordination - Support operational workflows across market data, compliance, support, and ITSM teams.

COMMERCIAL MANAGED SERVICES

DN Hub is a core component of CJC’s commercial managed service offering, supporting the delivery of structured and scalable Data Notification management services. Combined with CJC’s commercial market data management expertise, it delivers a fully supported operational service.

The price of managed service scales with the number of user IDs managed across client environments. This allows the service model to align with operational complexity and support requirements.

STANDALONE DEPLOYMENT

DN Hub can also be deployed independently by firms as a standalone platform, operated within their own market data and operational environments.

The standalone platform is available under a simple, fixed commercial model and lets firms benefit from the full DN Hub platform regardless of operational scale or notification volumes.

CJC is a trusted provider to global financial institutions. CJC delivers both DN Hub options in a secure, enterprise-grade operational framework designed to align with the governance, resilience, and security expectations of regulated financial markets.
