GoldenGate is our official recommendation for replication of data between environments

Other solutions I've seen used by customers include:

- Debezium
- Open Log Replicator https://github.com/bersler/OpenLogReplicator
- roll your own with LogMiner
- roll your own with PL/SQL and database links

And depending on the complexity of your needs, materialized views across database links can also be effective.
