JPA for querying in-memory data

Question

During an import procedure, I read tabular data from excel sheets. I want to perform some operation on this data: I want to sort, search by key, filter etc. Is it possible to reliably perform this kind of operations via JQL? thanks

Answer 1

I would use Space4J and simple Collections for something like this.

Personally I think all these ORM abstractions and layers are a distraction at the small scale problem domains, and are inflexible and added complexity at the other extreme.
