It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology.
Oracle could improve on scalability.
It could be more beneficial if MySQL can enhance its data masking functionality in the same way it has improved data encryption.

Native encryption ensures secure data management with a simple deployment
The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.
