4. Evolution of ”Database Implementations" on the Web

• PERL CGI scripts accessing files in file system (RIB)

• CGI stub accessing Oracle with PL/SQL or directly with oraperl

  • similar solutions with Sybase etc.

• Java Interfaces JDBC 2 or 3 tier (can access free MSQL or "expensive" Oracle)

  • Natural choice for a new project today

• CORBA emerging possibility in the future

  • Note that one of CORBA services called POS (Persistent Object Service) offers transparent interface to a generic storage medium, be it flat file system,RDBMS or ODBMS.
  • Fancy new systems like this IBM Component Broker bring also CORBA support to other legacy backends such as mainframes, CICS, TP Monitors etc.
