  Flawed JDO Points the Way to the "Objectbase"
Subject:   JDO can give us more than just JavaBean functionality
Date:   2002-04-25 08:02:56
From:   dion
Althought I agree that it can be trivial to reimplement JDO functionality for simple cases,
JDO gives you a lot more:


- Persistence Manager can do a lot of great caching, so you don't even have to go to the database (which is the #1 bottleneck)


- Tools allow us to push the data mapping OUT of code. I can view my database and point and click my way around.


- Relationships are a *lot* easier to manage in my opinion. I think it is a lot nicer to be able to say:


Cat poorCat = getPerson().getDogs().getLastCatEaten();


to traverse the relationships. Nicer than working with joins.


However skill-set does come into play. If you are an SQL geek, then you may want to stay in that land. JDO is not a silver bullet by any stretch, but it is an interesting technology, that will mature and become a great way to access persistent information (not only RDBMS)
