Hello,

I'm new with ORACLE and I am interested in following:

Client/server communication architecture.

My understanding is:
a)OCI: layer 1 - target platform networking stuff.

              layer 2 - ORA network libraries -
                             provide logical stream protocol for layer 3
              layer 3 - call interface (OCI)

     Is it correct or wrong?

  b)ODBC - it is another call interface. Does ORACLE
      driver implement him as a layer 3 (tight to stream protocol)
      or as a layer 4 (over OCI) ?

3) Is there any documentation which compares OCI and ODBC?

I think the ODBC driver contains a subset of OCI functionality... Does it contain something what OCI doesn't? Does it contain extensions to ODBC standard which covers additional OCI functionality?

4) Can I find somewhere the estimation of market percentage-

     How many people work with OCI and how many with ORACLE ODBC?
     How many tools are available for OCI and ODBC?

TIA --
