I don't understand what Dialog does...I'm on their page right now.

Superboyac,
Dialog is a large collection of large databases, mostly of peer-reviewed journals and the like. It includes, for example, about 16 databases on patents alone; plus equivalent and generally large classes of journal databases on chemistry, pharmaceuticals, financial, business intelligence, marketing, general news, agriculture, products, brands and trademarks, aerospace, and I could go on. For
quality of information, it knocks the Internet into a cocked hat, but depending on what you want it can be very expensive. The company I work for spends about $7,000 per year on Dialog, the great majority of it on patent searches.
One of the good things about Dialog is a command language that gives you precise searching. You can build up the search bit by bit, e.g. something like this:
s1 (toner? or developer?)
s2 (acrylic or acrylated or acrylate)(2n)bead?
s3 s1 and s2 # combine first two searches
s4 s3/eng # limit to English language only
So that's where I'm coming from, and perhaps you can see why I'm interested in powerful database systems rather than hierarchical trees. There are few such systems available at low cost. The only one I can think of is the DOS program Inmagic, which was declared freeware when Inmagic Corp. launched their Windows version, DB/TextWorks. And if you have to ask the price of
that, you can't afford it...
