Model Driven Software Development with UML - Back to the Root (or how KissMDA saves our Agile Development with Java...)

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.

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 the alre…

Open Data Initiative and Mashup

I found out following things as I implemented the WebApp:
Open Data Berlin needs to take care of their Open Data API. For the total population I need to get the Zip file, uncompress it and read the CSV file inside it, using Common Compress and OpenCSV Java Open Source library. For the result of election I have to work with Excel file using JExcel, also Open Source library. Amazing to see how complicated they did i…
