Learn what JPA and ORM abstract from the traditional JDBC model.
- [Instructor] So as we start to come to a conclusion…of this course, I would be remiss if I didn't at least…point out that there is JPA and ORM,…where they are similar, where they are different,…and what they mean to an RDBMS system.…Now first I'm going to start by talking…about why you use JDBC itself.…Now, technology itself is all about trade-offs,…so for every benefit you get from ORM,…you're going to get a problem,…and that's just the nature of what it does.…I can show you in most ORMs how to create…a Cartesian product by doing a simple one…to many join multiple times from a simple object itself.…
It's usually not what you want.…Cartesian products are not…a positive thing out of a database.…So every problem that you're solving with an ORM,…you're also causing new ones,…and that's one of the reasons why people like using…raw JDBC, and one of the reasons that I personally…advocate for it when dealing with an RDBMS system.…JDBC gives you full control,…but you're doing so with a lot of manual work,…and a lot of that is repetitive work.…
