What is the method for incremental data synchronization…

There are several commonly used methods for Oracle incremental data synchronization, including the following:

1. Utilizing Materialized Views: A materialized view is a logical structure defined based on a query, which allows storing the query results in a physical table. By using materialized views, one can create one or more materialized views to synchronize incremental data between a source database and a target database.
2. Utilizing Log Mining: Oracle database offers log mining technology that can capture and synchronize incremental data by analyzing database log files. Log mining can identify changes made to the database and apply them to a target database.
3. Using Oracle GoldenGate: Oracle GoldenGate is a powerful tool for data replication and synchronization that enables real-time incremental data synchronization. It achieves data synchronization by capturing changes made to the database and applying them to the target database.
4. Utilizing Oracle Streams, a highly configurable data replication and synchronization solution offered by Oracle databases, allows for incremental data synchronization by capturing changes made in the database and applying them to a target database.

Each method has its own characteristics, and the specific choice should be determined based on actual needs and environment.
