Wiki Roadmap 4.1 This document is written to represent the thoughts behind the wiki roadmap 4.1 and to reflect on discussions in irc. It is also a representation to an alternative Roadmap 4.1 The ultimate goal is to present everthing in an understandable overview to give everyone involved a clear mind over what's to come and to open up discussion.

Client Server Database (Oracle, Postgresql) JBoss Compiere ServerBean dbPort Package Web Webstore model Package dbPort Package PO - model Package AD GUI Engine Internet Browser The inherited architecture of Compiere. WWW Swing GUI

The inherited architecture of Compiere Comments There's something to say about that... About the web application (WWW) * Both Java Servlets and JSP are used (why using 2 solutions in the same project ?) About the GUI (AD) * Web package is used to check if the AppsServer is online * GUI uses server objects to manipulate the database * GUI talks via AD data models directly to the database This is clearly not such transparent architecture and the question is why there are 3 routes used to talk to the server and 2 ways to talk to the database.

Client Server SOAP (XML messages service) Database (Any DB tool) OQL (Object query language) JPA (Persistence Model) Hibernate or Toplink JSR (Script API) Pentaho reports Wiki Roadmap 4.1 AJAX GUI Reports GUI

Wiki Roadmap 4.1 Comments There's something to say about that as well... * AJAX: can this technologie be implemented AND let AD survive “as is” ? I don't think we want to throw away AD, after all AD IS the project. What we want is to improve AD. * Pentaho reports: ? * JSR Script API: the big advantage is that it can talk to other script languages then just Java. Great. But why should we need that for ? It will slow down Adempiere already under review for sqeezing better performance out of it. * SOAP (XML messages): that would replace the current server running ADempiere server ? Why replacing the technology we have with this one. SAOP is slower then what we have. * JPA (Hibernate or Toplink): would replace the current PO classes in Adempiere. I'm not opposed to new technology or a new standard. If someone can deliver proof that one of these gives better performance and is as easy to undersand and use as the current PO, I can see no problem in that. * OQL: advantage is that it talk to any database tool. Great, but we don't use just any database tool. The disadvantage of OQL is that this fact is slowing dramaticly because - it has to translate to the specific database - it takes no advantage of special features a database tool has We better serve a few databases with good performance then all database with poor performance. And, last point

Client Server SOAP (XML messages service) Database (Any DB tool) OQL (Object query language) JPA (Persistence Model) Hibernate or Toplink JSR (Script API) Pentaho reports I assume Compierians/ADempierians know their database and Java technology. We can not assume they know the new technology that would be used. Let me blank out what most of us don't know and will have to learn... (click) AJAX GUI Reports GUI You got the point.....

Client Server Database (Oracle, Postgresql) JBoss Compiere ServerBean dbPort Package JBoss Web Webstore model Package dbPort Package PO - model Package AD GUI Engine Internet Browser New proposal (still under revision, it's very early release...) click... WWW Swing GUI Compiere ServerBean dbPort Package PO - model Package

New proposal Comments * unify the way the application is talking to the database, only one way instead of 3 * get rid of the web package, this isn't doing much usefull... And most important: don't change technology just for the sake of the technology. We already have great technology, and we understand it (or should), we all joined this community for a reason... It's not the technology It's what you do with it
