JDBC in it’s documentation states that it has 4 implementations to connect to databases. I don’t quite get what the 4 implementations mean, I was wondering is JDBC truly database agnostic. That is, will I need “drivers” for each type of database, like for MYSQL (jConnector)?
I am writing an app to support Oracle, MySQL and MSSQL.

Thanks
Unfortunately, you will need drivers for all database types.
If you want to be truly database agnostic you need to use JPA:

With one of its implementations. One of the most popular is Hibernate:
