Java?

Vendor-independent? Java is owned by Sun Microsystems

Run everywhere? Java applications tend to bring their own VM

Thin clients? The required Swing Classes are large

Productivity and maintainability? DBMS Access and transaction control difficult Java is not a business-oriented language

16

Java?

Data base access? Java has not an integrated data manipulation language Java can not access most non-RDBMSs

Ready for large business applications? 30 % of all Java developers have appropriate skills 70 % of all Java projects fail

Gartner at ITexpo 2000

Skills Educating “procedural” developers is very expensive Java developers command high salaries Experienced Java developers are hard to find
