I have a third party system using Oracle 12C database to which I need to do data analytics.
For safety I don't want to do it to the production database server. For economical reasons I can't run another Oracle database server. For practical reasons I prefer to do it with a system I know better (PostgreSQL).
Is it possible to replicate a an Oracle 12C database to a PostgreSQL database? It is possible to do it in (near) real-time or on-demand but incrementally?
