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. ...

... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...
