Hi all,
just joined....
I'm doing a presentation (20th June), for one of my Uni subjects,
Comparing Objective-C with Java and I was hoping I might be able to
get some pointers from people on this list regarding the above
topic.
I've noticed that there is a group who have worked on an
implementation for Objective-C (objectpark.org) with their project
SOIL - but I haven't gotten a reply from them as yet.
For Java's persistence options I'm referencing the following paper:
[Atkinson, M. P. et al., Design issues for persistent Java: A
type-safe, object-oriented, orthogonally persistent system, , Proc.
of the 7th International Workshop on Persistent Object Systems,
Cape May, 1996.
http://www.dcs.gla.ac.uk/pjava/pjava-pos7.pdf]
which specifies...
__Goals for PJava__
The design of PJava seeks to provide an orthogonally persistent
system that meets the following goals.
1 No loss of safety when utilising persistence and ideally, an
increase in consistency.
2 No impact on the performance of programs that do not use
persistence; minimum performance
penalties and, if possible, performance gains for those that do.
3 Minimal changes to the language.
4 Simple, almost subliminal, use of persistence for many
programmers that can be satisfied by
a default model of transactions.
5 Sophisticated and precise control of transactional programming
for those that require it.
Would anyone be able to either point me in the direction of similar
projects for Objective-C (and more importantly documentation,
and/or discuss GNUstep options with me in relation to this topic?
It would be greatly appreciated!!
Thanks.
with regards,
