What is the method for replicating tables in Oracle Gol…

Oracle GoldenGate offers various ways to replicate tables, including the following methods:

1. Initial Load: GoldenGate can export data from the source table to the target table to achieve the initial load. This approach is suitable for situations where existing data needs to be imported into the target table.
2. DDL replication in GoldenGate allows for the replication of DDL operations on the source table, including creating, modifying, and deleting tables. This ensures that the structure of the target table remains consistent with the source table.
3. Real-Time Replication: GoldenGate can capture changes on the source table in real time and apply them to the target table, ensuring that the data on the target table stays synchronized with the source table.
4. Cluster Replication: GoldenGate can replicate data from the source table to multiple target tables to achieve high availability and load balancing of data.
5. Filtering Replication: GoldenGate can select only the data from the source table that meets specified conditions through filtering, reducing the amount of data in the target table and improving replication efficiency.
6. Transformation Replication: GoldenGate can transform the data from the source table during replication, such as modifying column values or adding calculated columns. This method enables data format conversion and data processing.
7. Data integration: GoldenGate is able to combine data from multiple source tables into one target table in order to achieve data consolidation and integration, making it suitable for scenarios where data from multiple source systems needs to be integrated.

The appropriate replication method should be chosen based on specific business needs and system architecture.
