Re: ORM

Sat, 03 Jan 2009 01:32:15 -0500

I don't want to get involved in a fight over ORM but I started a library for working with databases in a fundamentally different way than ORM. You could build ORM on top of it, I suppose, but it's not really my goal. If you are interested...

Thanks for valuable comments. I know some ORM frameworks already have solid solutions for some of these problems. Besides, I don’t target any specific solution or framework. My criticism is general and includes Java standard solutions. Most of criticism...

Desgin Patterns (DAO)

You may want to look into design patterns and Jt (Java Pattern Oriented Framework). It solves some of the issues that you identify (Simpler persistence API). ...

Re: RDBMS is totally unsuitable for representing objects.

Well a certain CJ Date would disagree and I'm with him. Much of what some consider Object/relational is what CJ Date would call "Relational done right" for example. Certainly there are RDBMS that handle complex types and inheritance such as...

For everyone interested I especially recommend the article “What's wrong with Hibernate and JPA” that can be found here:

And yes XML mappings should be immediately abandoned. I never understood how anyone could have possibly come up with that idea in the first place

Java Persistence Frameworks - a new hope

I absolutely agree with Ibrahim Levent in his criticism of Java Persistence Frameworks....

RDBMS is totally unsuitable for representing objects.

Mon, 08 Dec 2008 15:58:57 -0500

The current persistence problem is a bye-product of gross mismatch between relational database and the object oriented approach of Java. RDBMS is totally unsuitable for representing objects... No patchwork can solve this. RDMS handles 2-D...

Re: Buzzwords re-inventing the wheel

Hibernate application is in fact redefining the data. It all works in simple cases. All these mappings become too complex in a real scenario.
When this complexity gets outsourced/offshored, it becomes really unmanageable....

I read some (but not all) of this discussion and was disappointed to see the discussion was rather concentrated on the technology (software architectures), rather than what needs to be done....

Re: Lazy Loading network cost?

Sun, 07 Dec 2008 22:42:45 -0500

Specifically, when your object graphs are on a different box (say an application server) from your DBMS (say on a separate DB server box) - then you need to "materialise" object graphs on the app server (move the data over the...

Re: ORM needs more from SQL for efficent Object Graph construction

Sat, 06 Dec 2008 19:24:07 -0500

Said bluntly, SQL is not great for building *SOME* object graphs. Oracle exposing its MVC timestamp means an ORM vendor can use that to build the object graph *MUCH* more efficiently. I'm wondering if an OODBMS query language would be even...
