How do I handle sync conflicts?

Common strategies: last-write-wins (simple but can lose data), source-of-truth priority, merge changes (complex), or flag for manual review. Choose based on data criticality and conflict frequency.

Should I use real-time or batch sync?

Real-time for: customer-facing data, time-sensitive operations. Batch for: analytics data, cost sensitivity, systems that don't need instant updates. Many systems use both for different data types.

How do I maintain sync when systems have different data models?

Create mapping rules for field transformations. Handle many-to-one relationships. Account for fields that don't exist in both systems. Document transformations thoroughly.

Implement: monitoring and alerting, retry logic with backoff, dead letter queues for failed records, manual reprocessing tools, and audit logs. Design for failure recovery from the start.

Data Synchronisation

Keeping data consistent across multiple systems by automatically copying and updating data when changes occur. Essential for multi-system architectures.

In-Depth Explanation

Data synchronisation ensures data remains consistent across multiple systems. As businesses use more applications, keeping data in sync becomes critical for operations and accuracy.

Synchronisation patterns:

One-way sync: Data flows in one direction (source → destination)
Two-way sync: Changes in either system propagate to the other
Real-time sync: Changes sync immediately
Batch sync: Changes sync periodically (hourly, daily)
Eventual consistency: Systems converge over time

Sync challenges:

Conflict resolution (which change wins?)
Data model mismatches
Performance at scale
Error handling and recovery
Maintaining referential integrity

Key considerations:

What is the "source of truth"?
How to handle conflicts?
What triggers sync (event, schedule, manual)?
What data fields map between systems?
How to handle deletions?

Business Context

Poor data sync leads to customer frustration, operational errors, and bad decisions. Good sync ensures everyone works with accurate, current data.

How Clever Ops Uses This

We design data synchronisation solutions for Australian businesses, ensuring critical data stays consistent across CRM, ERP, marketing, and custom systems.

Example Use Case

"Two-way sync between Salesforce and HubSpot - when sales updates a contact, marketing sees it, and when marketing captures new leads, sales sees them."
