I am contemplating a project, and I have a question: What components would you use to build a business application in Ruby? Suppose, you were asked to write a business application. Typical, no-thrills business app. Reasonably small database, few dozen users (all internal), some reporting functionality, couple of batch interfaces, nothing fancy. To give an example, think about sales / stock control system for a wholesale trader of electronic goods. Or vehicle tracking system in a truck company. Or something similar. Naturally enough, one would want to do it in Ruby :) But for a job like this, you need a certain set of technologies, namely: 1. A database Java world: Oracle, MySQL or another relational DB of your choice 2. Some way to persist domain objects and manage transactions Java world: entity EJBs, JDO, hand-coded DAOs, O/R <censored> mappers, etc 3. An RPC (remote procedure call) mechanism for communication between the front-end and the back-end (assuming that the front-end is a thick GUI). Java world: session EJBs, servlets 4. A thick GUI Java world: Swing 5. A Web GUI Java world: JSP, XSLT, XMLC and all the other stuff 6. An asynchronous communications infrastructure Java world: message-driven EJBs Doing the whole thing in Ruby is already experimental enough, so the choice is limited to mature, production-grade stuff. What would you use? If this has been discussed before, I am sorry. Please point me to a relevant thread in the archives. Best regards Alexey Verkhovsky
