Lofi model @ work

TigerTeam TRIMM – Model Driven Generator is just Open Sourced in July 2013. I myself never heard of this product before and found this product by coincidence as I tried to find a JPA 2 standalone cartridge / generator available in Internet. I know that AndroMDA has some cartridges to persist Java objects but as far as I know AndroMDA only support persistence in the context of EJB 3 not as standalone JPA. After I found this product I began to analyze the code at Bitbucket.org and found out that the idea with the Events and Listeners as Extensions  is a very good idea. TRIMM also uses Maven completely and does not have any dependencies to Eclipse plugins, so you are Eclipse independent. Special to this framework is that it uses its own metamodel and does not use UML2 metamodel for the generators. TRIMM should work for MagicDraw and Enterprise Architect and it can read the files directly from those UML tools. It also uses its own Java code generator which is basically based on...

After working since 2004 with MDA (Model Driven Architecture) / MDSD (Model Driven Software Development) technologies like AndroMDA, oAW, etc. always in context of Java technology and UML (Unified Modelling Language) I feel like that we need just another MDA tool. Why? Past  The first experience with AndroMDA in the year of 2004 was great! At the end you don't need to code those boiler plate codes in EJB 2.x. AndroMDA generates everything for you. You also have the documentation of your application always up to date. This is a very important thing, since if you have more than one hundred entities you definitely need that actual documentation to be able to extend the application. AndroMDA offers a lot of mature cartridges like EJB 2.x, SpringFramework, Struts, Hibernate, JSF. The idea with cartridges is just gorgeous. IMHO it is possible to have a general application architecture for most business applications. So if you are using SpringFramework and Hibernate you can reuse...

It's quite amazing to see the same things happen again and again... Reinventing the wheel seems is the way in computer science to make things better ;-)  To begin this blog with, which is a comment of the discussion in TSS about Sculptor : The idea of Sculptor is not new, also ArchitectureWare is not new... MDA/MDSD is not new as well... Here are my opinions about Sculptor and AndoMDA and general about MDSD/MDA: (1) I'm a very satisfied user of AndroMDA. AndroMDA is a very good framework for MDSD/MDA and is just comparable with ArchitectureWare. The latter is the framework in which Sculptor is written. (2) Sculptor is comparable with AndroMDA Cartridges , which allow you to generate codes for its reference architecture . AndroMDA offers a lot of production-ready cartridges like: Java (general purpose) EJB, Spring, jBPM (business layer) Struts, JSF (presentation layer) ... And also for .NET! All these cartridges are already available since more than 3 y...

I'm collecting the advantages and disadvantages using Groovy for JUnit and found following interesting stuffs... Advantages: You don't need to implement inner classes which are very awful and bloat your test codes. Instead you can use closures . Using closures for writing your mock objects can make your test codes smaller and more compact ! File operations are very easy to implement thanks to AntBuilder . How many times do you need to make some file operations (delete, mkdir, ...) within your test codes? Doing this with java.io is not fun at all. Using AntBuilder for this purpose is a good thing, since Ant is predestinated to do this job. If you think that you could do the same thing in pure Java, you will find that this takes a lot more work. Using Ant directly in Java is unfortunately not straight forward. Example: to use the unzip Ant task you need to use the Expand Java class, which is not documented properly (so you need to dig into the Java source code). In Ant...

My first book in German language about MDA (Model Driven Architecture) and VOFI (Visualization of Financial Implications) is now available: Anwendungsentwicklung mit Model Driven Architecture – dargestellt anhand vollständiger Finanzpläne This book is my doctor dissertation from the year 2006 and is now published within the series of Advances in Information Systems and Management Science from Logos Verlag Berlin . Cover of the book Contents of the book The good thing is that I will offer a free download for the PDF version - many thanks to Logos Verlag which makes this possible! So, if you can read German, you are welcome to download it ;-) For this purpose I'm searching some sponsors. As soon as I get some sponsors I'll put the PDF version somewhere in the internet. So, stay tuned! If you want to buy it, just order from Logos Verlag Berlin : ISBN 978-3-8325-1480-8 Or go directly to this order site: Order MDA VOFI Book from Logos Verlag Berlin Happy reading!
