I’m a java developer, currently starting developing a hospital management system that will server patients, doctors, accountant, …. etc the system is really huge that may have 900,000 records/day, data is really growing so fast, for that i’m confusing in which database to use since i have the following options: (Percona Server(Mysql), Oracle, SQLServer), since the application will run on network with average of 45 online users.
I hope to find a good answers here.
Thanks in advance
If you have been working with MySQL for 6 years then stick with it!
You don’t want to add the burden of learning another database as well as having to develop your application.
If you are unsure if MySQL is up to the job then run some tests. Write an app that runs multiple threads inserting 1M rows and see if your servers can handle it.
I’m guessing the brand of the database you choose will be less important than the performance of the platform (machines) it is running on.
