Getting Started with SAP Hana Database
This getting started gives some clues to start working with SAP Hana
The database structure can be entirely reversed in Metadata and then used in Mappings and Processes to design and adapt the business rules to meet the user’s requirements.
You can refer to Connect to your Data page which explains the procedure.
For performance purposes, some of the SAP Hana Templates are optimized to use the SAP Hana IMPORT FROM statement to load data into the database.
For this, Semarchy xDI will extract source data to temporary files and then load them through the IMPORT FROM statement.
To use IMPORT FROM statement, SAP Hana needs to have access to the temporary files to load. SAP Hana Templates supports sending the temporary files through SSH.
This method consists of sending automatically the temporary files through FTP on SAP Hana machine.
If you want to use this method, the first step is to prepare the SSH connection by creating an SSH Metadata.
Create an SSH Metadata, fill in the target SAP Hana machine connection properties, and finally define inside a folder in which the temporary files will be transferred.
When this is done, drag and drop the SSH folder on the SAP Hana Metadata and rename it to 'TARGET_SSH'.
|The Metadata Link can also be drag and dropped on a schema or on a datastore node instead of the root server node, if you want to customize the temporary folder for each datastore, for instance.
Your Metadata being ready and your tables reversed, you can now start creating your first Mappings.
The SAP Hana technology can be used like any other database in Semarchy xDI.
You can refer to Work with Mappings page which explains the procedure.
