What modeling tools do you have experience using? Of these, which do you find the most useful or powerful?
Data Architects should have a solid understanding of data modeling whether or not it is one of their main responsibilities. If you do not have experience using modeling tools, indicate the ones you are aware of and which you know to be the most useful. Interviewers will appreciate that you have at least a basic knowledge of modeling tools.
"My experience with data modeling tools has been primarily with Oracle SQL Developer Data Modeler. I also have had very limited exposure to PowerDesigner. I found Oracle Data Modeler to be more than sufficient for my needs with its forward and reverse engineering capabilities. However, I have learned that PowerDesigner offers valuable features such as the ability to support a substantial metadata repository and a variety of output formats. One of the more valuable features seems to be the ability to use different modelling techniques that are targeted to different audiences. Of the two tools, I believe PowerDesigner is worth a try for its abundant features and user friendliness."
