Re: SQL for JSON?
- View SourceTrimQuery solution is right pretty, but.... not for tree-based
Visitor pattern and XPATH on XML realy designed for tree.
written by Steffen Meschkat <mesch@...>. It's realy titanic
solution, but it's designed for XML.
function visit(aTree, anAcceptor, aVisitProcessor)
I proceed from the assumption:
- 90% tasks are based on search by equals or like.
- 10% tasks can be realized by custom "acceptor" and/or custom "visit
Moreover, Visitor allowed to modify tree so well as search from them.
For example, I can design code, that removed from JSON data structure
all persons whose birth day arrived on full Moon (20 lines of code).
Java Visitor on Tree vs. Events named Digester
Of course Visitor is not competed with SQL (especially on server with
indexes, cache etc), Visitor is not a rival for XPATH on XML.
TrimQuery solution is very good and very helpful, but for JSON
JsonTools is preffered more...
