Very well, the internal secret is oracle uses the great Single Sign-On (SSO) to simply achieve the amazing function.As well known as the Single Sign-On (SSO) technology has been used on oracle (https://www.oracle.com/) over the past many years. Are you wondering the underlying principle? Fortunately #NikkiSiapno uses the concise and easy-understanding GIF image (https://lnkd.in/dmdtqTqU) to reveal this mysterious veil.
We supposed "Identity Provider" is oracle own's IAM mechanism located in its cloud, "Service Provider 1" is the 1st APP I mentioned "LiveSQL", "Service Provider 2" is the 2nd App I mentioned "Forums or AskTOM".
The last 3 Apps uses the same principle to achieve SSO function (only listed the first 2 Service Providers). Similarly we supposed "Service Privoder 3" is the 3rd App I mentioned "DevGym", "Service Privoder 4" is the 4th App I mentioned "LiveLabs", "Service Privoder 5" is the 5th App I mentioned "SQuizL".

#NikkiSiapno uses the incredible GIF image (https://lnkd.in/gT2Q9Wyq) to pertinently and vividly describe what's the potential and essential differences between CONCURRENCY and PARALLELISM … I've just decorated it to become a fabulous MP4 file, which has been integrated the special effects and melodious music … 😉

Currently Oracle GoldenGate supports 6 topologies to enable data replication and integration across different environments, they are as below:
◾ Undirectional Replication
◾ Bidirectional (Active - Active) Replication
◾ Peer-to-Peer (Multi-Master) Replication
◾ Broadcast (Hub-and-Spoke) Replication
◾ Consolidation (N-to-1) Replication
◾ Cascading ReplicationThanks to #Ibrahim Kmail's gif image I just embellished or decorated it to becoma a small video *MP4* file.
