Next: Access to Data Sources and the ESO SkyCat Tool . ... We describe an implementation of Dynamic Queries (DQ), a recently developed method as an alternative to the perceived complicated SQL-type operations on relational databases by a very intuitive graphical interface. This prototype implementation, written within the NEMO package, uses ASCII sliders and the PGPLOT graphics interface and uses a novel interactive analysis back-end tool that is dynamically associated with the query. ...
