	ETL and CDC with databases Create a source Connection for the relational database Create a destination Connection for the relational database. Create a new `Database to database` Flow. Add a new source-to-destination transformation. Configure mapping. Test transformation. Read the full article
	ETL multiple tables by wildcard Create a source Connection for the relational database Create a destination Connection for the relational database. Create a new `Database to database` Flow. Add a new source-to-destination transformation. Specify the fully qualified wildcard source name in `FROM`. For example, `public.`. Configure the destination name in `TO` using either only an asterisk character (``) or any part of the destination name with the asterisk character (`public.*`). Read the full article

Manufacturing company Data synchronization between the OLTP database and data warehouse Read the case study	"To incrementally load the data from the source into the destination, we will be using a feature called `Change Replication`. In order to work, the change replication requires each source table to have a so-called `High Watermark Field`. In our case, all source tables have a column called `timestamp`, which is a binary-encoded timestamp of when the record was last modified or inserted."
