Figure 6 .9 : SAP H ANA blockchain service

The two components that make up the SAP HANA blockchain service are as

follows:

1. Adapter of blockchain

2. Service of integration

Adapter of blockchain

Deployed on SAP HANA, the SAP cloud platform gets connected by a Smart

Data Integration (SDI) connector. The blockchain service which helps in

exchanging data back and forth between SAP HANA and the blockchain

platform is the blockchain adapter of SAP HANA.

Blockchain data is represented as virtual tables in the HANA database, and

blockchain data can be replicated to the HANA database using these virtual

tables. Changes to the blockchain data are continuously identified and applied

to the HANA tables.

Service of integration

To configure connection properties on the Cloud platform side is the

integration service of SAP HANA, which helps to deploy on the SAP cloud

platform.

APIs are provided to fetch data from blockchain nodes, write data back onto it,

and are used to manage the data exchange between SAP HANA and the

blockchain by the blockchain adapter of SAP HANA.
