Scala to extract XML from SOAPUI-project file
I've created a small scala-script to extract messages from SOAPUI. Writing this was surprisingly easy, and certainly faster and more pleasant then processing the SOAPUI manually.
SQL Performance
If you have to access persisted data, of course, you do not have to necessarely use SQL. But in case you do, knowing something about SQL-performance helps.
I just did a this 3-minute test on SQL performance (for Oracle), with 4/5 score. Pretty fine.
The answer I failed was about multi-colomn indices. When you have a index containing multiple columns, if you use one of those columns in a where clause, the index is used. However, the index can only be used efficient if you use at first column.
