i2Active is used for dual-active data replication between homogeneous databases. Through a flexible architecture (one-to-one, one-to-many, or many-to-one), it allows data users to obtain the required accurate data in real time for data analysis, testing, disaster recovery, simulation and other scenarios. This software can achieve fast data capture in milliseconds, timely, safe and reliable data transmission, and can be adapted to production systems of various scales.
