Replicating data from HANA db to other HANA system in real time

You can also try using SAP Smart Data Access feature to transfer data in real time. In SAP HANA system, you can use Smart Data Access (SDA) option to replicate data to HANA database from other data sources where you create virtual tables, which are linked to tables in the remote system. You can perform read/write operations on these virtual tables - SELECT, INSERT, and UPDATE.

Smart Data Access creates a virtual layer that allows you to access remote data without physically moving it to your local HANA system. This approach provides real-time access to data while maintaining a single source of truth in the remote system.

Supported Remote Systems

Different types of remote systems can be used under Smart Data Access ?

• SAP HANA - Other HANA databases for cross-system data access
• Sybase - Sybase ASE databases
• Teradata - Teradata data warehouse systems
• Apache Hadoop - Big data clusters and HDFS
• Oracle - Oracle database systems

How Smart Data Access Works

Implementation Steps

To set up Smart Data Access between HANA systems, you need to ?

1. Configure the remote data source connection
2. Create virtual tables pointing to remote physical tables
3. Set up appropriate user permissions and access controls
4. Test the connection and data access operations

To know more about SAP HANA Smart Data Access replication, you can refer to the official SAP documentation ?

Conclusion

Smart Data Access provides an efficient way to replicate and access data from remote HANA systems in real time without the need for physical data movement. This approach ensures data consistency while enabling cross-system operations through virtual tables.
