data base and software for organic compounds

 Dear Netters,
 I am interested in the information about the availability of
 the data base of Aldrich and/or other chemical structure (3D)
 data base. Are there any differences between this (these)
 data base(s) and Cambridge data base? Is there any data base
 software available, which can be used to handle a small data
 base (less than 200 structures of small organic compounds),
 in both academic or commercial levels? Is there any review
 article recently published about these subjects?
 For those who want to discuss about price, comparison of the
 performance between different commercial softwares, please
 directly forward the message to me.
 Thank you very much for your help and/or cooperations!
