  1. CORBA 제품 동향 INPRISE Korea Technologies for Distributed Information Systems Enterprise Solution Team

  2. Agenda • Concept • Technology Trend • Market Share • Product • Architecture • Future

  3. Concept “The Distributed Application is the Application” “Middleware that’s Everywhere”

  4. Technology TrendBefore & After Before After

  5. Technology TrendBusiness vs IT BUSINESS PRESSURES IT CONSTRAINTS Faster Time-to-Market Post-Merger Absorption Enterprise Extensibility Customer Satisfaction Rapid Product Obsolescence Investors: Increase ROI Leverage Business Opportunities Avoiding Vendor Lock-In Costly/Scarce IT Personnel Project/Time Bottleneck Legacy/State-of-the-Art Conflicts High Failure Rate of IT Projects Risk of Low Quality & Reliability Inflexible Development Environment

  6. Technology TrendDistributed Object Computing Model • To build an infrastructure that can quickly adapt to change • Based on component-based architecture • Components can be new or existing code modules • Multi-tier Component Architecture offers: • Faster application development • Longer application life • Easier application maintenance • ORB is the foundation for this new architecture

  7. Technology Trendn-Tier Business Logic (Calculation, Compute…...) Generic Logic (Sort, Common logic…...) Business Logic ‘Proxies’ Data Access Layer (Select, Insert, Update, Delete…...) DatabaseServer DBMS Client

  8. Technology TrendJava Programming Language • “Write Once, Run Everywhere” • Portability across platforms • any platform and operating system • Internet programming • IIOP & Tcp/ip • Object-oriented language • no pointers, fewer memory management, simple syntax and method, garbage collection, exception handling, integrated thread support • Component model • provided by a number of Java classes into a single component • Interfaces defined independently of implementations • distributed object application
