Choosing an Update Strategy
The choice of synchronization interval should be based on business criticality. Do not attempt to synchronize everything in real-time, as this creates excessive infrastructure load.
- Operational Data (orders, payments): Use an event-driven approach. Updates should occur instantly after a change in the source system.
- Reference Data (prices, details): It is optimal to use scheduled batch synchronization (e.g., every 4 hours or overnight), which reduces the risk of database locks.
Conflict Resolution and Quality Measurement
When data is changed simultaneously in different systems, conflicts arise. Apply the "Golden Record" rule: designate the CRM as the owner of contacts and the ERP as the owner of pricing policy. If a record is updated in both places, priority must be given to the owner system.
To measure data staleness, use timestamp monitoring. Implement a simple report: "Time of last synchronization minus time of last change in source." If this metric exceeds the allowable limit, the system should initiate an incident. Upon detecting delays, check channel bandwidth and message queues. In the case of conflicting updates, instead of automatic overwriting, route the data for manual review by a responsible employee. Such an audit allows you not only to maintain data integrity but also to detect technical "bottlenecks" in your IT architecture in a timely manner. Focus on ensuring that business processes do not stop due to version mismatches.
