Overview You will walk away understanding: 1. Similarities and differences 2. Statistics on the industry 3. Suggestions

Official Definitions What is Microsoft.NET?.Net is a set of software technologies for connecting information, people, systems and devices. What is Sun’s J2EE J2EE is a standard for developing multi-tier enterprise applications.

1. Similarities and Differences There are more similarities between.NET and J2EE than differences.

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 viruses cost billions Slammer worm: $950-$1.2 billion Sobig and MSBlast/LoveSAN : $32.8 billion of economic damages.

Microsoft Security Quote: " W e didn't just fall off the turnip truck just a year ago and decide we should think about [security]. We started three years ago.” - Craig Mundie Microsoft Senior Vice President Chief Technology Officer Nov. 13, 2002

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!!!

Statistics Industry trends and the state of the union.

% of Developers worldwide

Gartner survey Vendor Targeted Projects Microsoft.Net was targeted by 58% of integrators IBM Websphere (J2EE) was targeted for 40% Oracle (J2EE) was targeted for 31% September 2002, Gartner survey of consulting and systems integration vendors in North America. (not out of 100%)

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 Any Application Server Generic applications XML Web services J2EE WebSphere application XML Web service.NET application XML Web service SAP PeopleSoft Siebel XML Web service Web Services for cross platform integration
