Hello!

I'm trying to map three-dimensional array from PostgreSQL with Hibernate. A need to store weights of Multi layer neural network. How should I do it better?

All source I've met was too old. It seems to me that there are more convenient ways to cope with it.

Thank you!!!

UPD: I need Double[][][]

What model do you want to represent in the DB exactly? Multi-dimensional array is a loose concept, i.e. Java has an array-of-arrays concept, while PostgreSQL's array must be "rectangular". -- Hibernate does not support array types out-of-the-box. – pozs 21 hours ago

we'll need slightly more information. i.e. will it always be rectangular, or do you use that fact that in Java, you have array-of-arrays? Some example data (a few rows) and how you are going to use the elements' value, etc. – pozs 21 hours ago
