We have evaluated PowerTier 5.12.
To give a short answer:
Strength:
- Starting from an UML diagram you get your CMP entity beans
up nearly in no time (for a given UML diagram).
- good CMP because this is Persistence strength (underlying
OR mapping layer)
- Rational Rose and TogetherJ (beta) integration
Weakness:
- everything else ;-)
To be serious:
- only EJB 1.0 today
- generated Bean code with fixed insertion points (marked by
comments)
- only entity beans can made persitence (no support for persistence
dependent objects)
- for n:m relationships between entity beans you need to create
"relationship entity beans" just to navigate
- much propietary code (ok, it's EJB 1.0, wich is underspecified
as we all know)
- long turnaround time (generate beans, generate stubs/skeletons,
compile)
- no easy IDE integration (maybe we are just to stupid to find a
way ?)
- dynamic queries/finders are based on SQL breaking the mapping
abstraction (findBySQL() needs to know the actual table and column
names)
A last word:
PowerTier does not hide that it is coming from an
OR mapping/persistency layer vendor who tries to build an EJB
server/container.
