Build a private database by replicating part of data in the production database in real-time.

Replicate to various target DBMS with global CDC-level replication performance
Reduce the cost of establishing a replication system while maintaining the work level.

Upgrade, migrate, or win-back the operational database without interrupting the existing system.

Realize zero downtime by simply switching services from ‘As-Is’ to ‘To-Be’ after the migration completes by replicating the ‘As-Is’ system and the ‘To-Be’ system in real-time.

Prevent data losses from service interruption and provide high stability. Verifies the data migration integrity before switching the services.

Prevent data loss through continuous data replication.

Expect cost reduction as the target server specification does not need to be the same as the original server.

Provide high availability if the specifications of the source and target servers are the same (HADR)

Compared to Oracle DBMS engine level Active-Standby

No need for crash recovery in case of failover, so service is switched to standby quicker.

Can distribute inquiry task since standby server is in operation.

Realize storage redundancy automatically.

Compared to Oracle DBMS engine level Active-Active

Support high speed replication because 2 phase is not committed
Can also be built in WAN networks

Provide HADR(High Availability & Disaster Recovery)

In-doubt stage occurs for a certain period of time
Requires data conflict resolution and data loopback prevention

Check data consistency independently of replication

Starting with the first full inspection, each subsequent inspection is verified only on the update data block based on that point in time

Continue to reduce the time gap in subsequent verification section until the verification time of the nth order becomes zero.
