Remote data table mapping enables to store Data set data in a remote database instead of the database used by BellaDati. In that case, data are stored only in the source database and the mapping between BellaDati and the source database table is done by a intermediate database view located on the remote storage. Currently, PostgreSQL and Oracle Database is supported. UsageTo use Remote data table mapping, following prerequisites are required:
The Remote data table mapping is set in the Advanced settings of the data set. If all prerequisites are met, an option to configure the mapping is displayed. After clicking on Edit, the page for Remote mapping configuration is displayed. If the mapping is was not configured yet, there is a button to create a new mapping. Next, the user has to specify from which database table should BellaDati load the data. It is necessary to specify the name of the table with the tablespace (or user for Oracle) - e.g. "MYDATA"."SOURCETABLE". To confirm, user needs to click on Save. As the next step, user has to map the columns from the database table to the actual attributes and indicators of the data set. Once configured, user has to save the configuration and click on Recreate mapping. After confirming, the view is created (or updated) and data are available in the data set. Editing existing mappingTo edit existing mapping, user has to click on Edit. After that, the user can do following actions:
