About Factory Method and Abstract Factory (design pattern)Hi everyone,
Sorry, I don't know what group to post this problem, I think may be this group is suitable. I'm styduing DAO (Data Access Object) pattern in this link http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html. While I've read about implementing Data Access Objects by Factory Method Pattern (http://java.sun.com/blueprints/corej2eepatterns/Patterns/images09/figure09_07.gif) and Abstract Factory Pattern (http://java.sun.com/blueprints/corej2eepatterns/Patterns/images09/figure09_08.gif). I don't know what is difference things between them, they're seem the same pattern. So my question: in above article, what are difference about these patterns ? Sorry about my poor English :) -- Duy Lam Phuong Granted, this is a general question about design patterns, but it
revolves around implementations in Java, so you might want to look in Java-specific forums. That being said, there isn't a difference between the two images that you have shows. They are the same pattern. The first image just shows the complete Cloudscape implementation of the factory, while the second diagram shows a partial implementation for three different providers. -- Show quote- Nicholas Paldino [.NET/C# MVP] - mvp@spam.guard.caspershouse.com "Duy Lam" <duylamphu***@gmail.com> wrote in message news:%23vogNBFMIHA.5400@TK2MSFTNGP04.phx.gbl... > Hi everyone, > Sorry, I don't know what group to post this problem, I think may be this > group is suitable. > I'm styduing DAO (Data Access Object) pattern in this link > http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html. > While I've read about implementing Data Access Objects by Factory Method > Pattern > (http://java.sun.com/blueprints/corej2eepatterns/Patterns/images09/figure09_07.gif) > and Abstract Factory Pattern > (http://java.sun.com/blueprints/corej2eepatterns/Patterns/images09/figure09_08.gif). > I don't know what is difference things between them, they're seem the same > pattern. > So my question: in above article, what are difference about these patterns > ? > > Sorry about my poor English :) > > -- > Duy Lam Phuong Nicholas Paldino [.NET/C# MVP] wrote:

Thank you, i also think it's the same :( -- Duy Lam Phuong  |
