For meanwhile more than 25 years I am writing computer programs. More than a decade I spent with programs accessing databases, virtually always relational ones. I soon learned that this is rather hard work. Not only that you need to know about the theory behind RDBMS iself, but also you need to know the technical APIs (like ODBC, ADO, RDO, JDBC, JDO, JPA, CMP, ...), the structure of...
What it means to speak German fluently and to be able of C++ Several years ago one of our key coders moved from the south of Germany (where our HQ is located at the Black Forest) to the cold and rainy north, so we had to to find a suitable substitute.

For many years I am using XSLT now for a lot of tasks in both, development and runtime environments: Source generation, creating HTML from XML data, or even rendering SVG vector graphics from XML finance data. But what really bothered me was that the XSLT transformer contained in Java (even in Java 6's latest release) was just able to do XSLT 1.0 but not XSLT 2.0. XSLT (and XPath) 2.0 comes with...
