Staging BigQuery → <Transform> → ODS BigQuery |
Data Mapping Staging => ODS (BigQuery SQL views)
The spreadsheet below presents all data transformations from Staging tables to ODS tables. This steps aims to structure the files in the target table format and checking if the column's type (schema) are conformed.

For the DM dataset (DM_Conductivity), we have the views on the top of the tables before. As defined in the convention, there is no need of the abbreviation "conduct". No need either of Talend jobs.
Orchestrating Jobs
All the jobs are run in sequence under the follow job and project name on Talend Cloud:
