Is it possible to import the tables from Oracle Database to Data Service?
It is recommended to manually create the entities in the Database and then write a process (workflow in UiPath) to copy data from Oracle DB to Data Service using UiPath.DataService.Activities as mentioned in the Update Entity Record .
Activities are available for both the systems (UiPath.Database.Activities and UiPath.DataService.Activities ) , also Batch activities can be utilized for Data Service to write 1000 records at a time as mentioned Designing The Workflow .
