I started reading ofbiz documentation to be familiar with it. I look at the artifact document here: https://cwiki.apache.org/confluence/display/OFBIZ/Framework+Introduction+Videos+and+Diagrams?preview=/7045155/14286869/18ArtRefDia.pdf I'm truly amazed by this diagram.
There is only (5) colored big boxes. Are they virtually serving as containers? For example, the Entity Engine serving as a container to produce entities, that can be created by physical SQL engine? But what is this Entity Engine implementation? Is it a Tomcat container instance? I imagine Servlet Container to the top right of the diagram is implemented by Tomcat, is that right? The request flow is like a loop to me. The CS: Request: Event are fed into Control Servlet: Request part. What are the CS: Request: Event files and what are the control logic for this part to happen? >From this document: >https://cwiki.apache.org/confluence/display/OFBIZ/Entity+Engine+Guide. The >document said "The patterns used in the Entity Engine include: Business >Delegate, Value Object, Composite Entity (variation), Value Object Assembler, >Service Locator, and Data Access Object." The number of patterns is much less >of the number of Entities to be managed? Is that all the patterns? Is there >other reference that I can learn more about those Entity patterns?
