- It is possible to implement workflow using a rules engine, much as it is possible to write your own workflow using Java. Of course , you don’t get the graphical designer that JBpm has. http://firstpartners.net/2006/02/21/jboss-workflow-jbpm-and-jboss-rules-drools/

Scala Implicits: a dose of Magic | Part 1

http://lalitpant.blogspot.com/2008/08/scala-implicits-dose-of-magic-part-1.html Conversions of a method call receiver: for this type of conversion, if a non-existent method m1 is called on an object of type X , the compiler makes an attempt to convert this source object to a target object of a type Y that contains m1. For this to succeed, a unique implicit method of type (X => Y) should be in scope at the point of call. Conversions to an expected type: for this type of conversion, if a method m2 takes a parameter type Y, and it is called with a parameter x of type X, the compiler makes an attempt to convert x to a target object of type Y, which is then passed along to m2.

I was whining recently about how my scala-code is java in poor disguise. I started reading the scala by example pdf that also comes with the scala installation.
As alluded to as a possibility previously , I'm happy to announce that improved exception handling with multi-catch and final rethrow will be part of an upcoming JDK 7 build. Improved exception handling is joining other Project Coin features available in the repository after successful experiences with a multi-catch implementation developed by Maurizio Cimadamore . http://blogs.oracle.com/darcy/entry/project_coin_multi_catch_rethrow

The last nine months I have been running my own business together with some friends ( Triental AB ). We are building a product suite for private banking and wealth management with a focus on portfolio management, analysis and simulation. One of the great things of being your own is that you get to choose whatever technology you like and think is best suitable for the job. http://jonasboner.com/2008/10/01/real-world-scala-introduction/

http://www.scala-lang.org/node/1403 Domain Specific Languages (DSL) written in Scala have become powerful tool in the hands of Scala programmers.

DSLs - A powerful Scala feature | The Scala Programming Language

In this post, I'm going to attempt to create something similar to Ruby on Rails (or rake's) db:migrate scripts in Scala. I'm not going to actually implement features, just show how one can go about constructing a DSL in the Scala language.

This post is intended for Ruby developers. The idea for it came after numerous discussions with fellow programmers about state machines and workflow engines. What motivates me for posting is the publication of the 3rd issue of the excellent Rails Magazine. http://jmettraux.wordpress.com/2009/07/03/state-machine-workflow-engine/

The Process Virtual Machine

There are many process languages for Business Process Management (BPM), workflow and orchestration. For simplicity we'll refer to that collection as workflow for short.
Workflow Business Process Management systems and rules engines go hand in hand.

Example of an object-oriented model. [ 1 ] An object database (also object-oriented database management system ) is a database management system in which information is represented in the form of objects as used in object-oriented programming . Object databases are different from relational databases and belongs together to the broader database management system .
