Hello everybody:

I am doing a study (some kind of a survey) about different topics covered by diferent DBMSs.
In particulary, I am interested to know some topics (covered or not) by a particular DBMS.

Then, if anyone can help me I apreciate. Perahps some publication or paper about a comparision study between the more representatives dbms actually including ORACLE v7 , SYBASE v4, INGRES v6.3 , INFORMIX v.5.

Particulary, I am very interestd in the following topics :

• Basic characteristics:
  • Data types supported, integrity and manipulation data languages
  • 3 GL
  • Development tools and 4 GL
  • Securuty, protection mechanisms
  • Administration and management tools
• Distribution:
  • Data
  • Applications
  • Models (client-server, RPCs, etc)
• Support to images (multimedia) and other blobs
• Integration with packages (microinformatic packages) to help in decision support and other tools
• Implementation of standards (in "jure" and "fact")
• Performance and kind of platforms supported in a network environment, and characteristics of those platforms (memory, disk, Operating System, releases, etc )
• Communication protocols supported in a distributed environment
• Integration with CASE tools

If somebody knows some paper ftpable from some archive, please send me.
