Similar Language Functions
Although each language has its own syntax, their
functional equivalence is essentially the same.
Syntax Example
VB.NET:
if x > 1 then
DoSomething()
end if
JAVA / C#:
if (x>1) {
DoSomething();
}
For a programmer, language choice is more
aesthetic than functional.
The real difference is in the libraries.
DIFFERENCES
Difference: IDE
Microsoft’s Visual Studio.NET 2003
Powerful WYSIWYG designer
Easier to use drag-and-drop development for
both thin and thick client
Handles lots of the plumbing on a webpage
= saves lots of web coding time
Sun’s Project Rave
Not released yet
Difference: Security
As of 2003, there are over 84,000
computer viruses.
87% are MS Windows viruses.
2003 viruses cost billions
Slammer worm: $950-$1.2 billion
Sobig and MSBlast/LoveSAN : $32.8 billion of
economic damages.
Microsoft Security Quote:
"We didn't just fall off the turnip truck just a
year ago and decide we should think about
[security]. We started three years ago.”

Big Difference
Vendor lock-in
vs.
Vendor neutral
Advantages of Vendor Neutral
Increased Competition:
Cost
Increased External Performance
Fine Tuning
Specialized Tools
Better Customer Service
“Best-of-Breed” = The best solution
Vendor Freedom
Disadvantages of Vendor Neutral
More cooks in the kitchen =
More integration problems
More compatibility problems
especially versioning problems
between vendors
More fine tuning feature use =
more proprietary lock-in
Increased potential for
deployment difficulties
Advantages of Single Vendor
Less integration
Products come bundled
Compatibility among products of the same
version
Internal performance increase
Easier deployment
Advantages of Single Vendor
No passing the blame!!!

Reality
Most large companies will be running both
platforms for years to come.
"Gartner predicted that through 2005, more
than 90 percent of midsize to large
application development organizations
most likely will use both Microsoft and Java
technologies."

SUGGESTIONS
Suggestion: Be flexible
Standardize on a platform, but don’t let
standards dictate the best solution. Choose the
right solution for each individual problem.
Suggestion: Use Web Services
