  1. J2EE PET STORE &.NET PET SHOP Yong-Han Lee & Charles Harsch

  2. Introduction Project Description

  3. Recapitulation J2EE Pet Store & .NET Pet Shop Business Model

  4. Purpose of Pet Store & Pet Shop • Illustrate basic usage of J2EE technology and .NET technology • Demonstrate current best practices in system design.

  5. Comparison of J2EE PS and .NET PS • J2EE: platform-independent, JAVA-centric • .NET: Windows-centric and language-neutral • Design goals of J2EE Pet Store and .NET Pet Shop were the same • Almost the same performance

  6. Business Model

  7. Technological Architecture Model

  8. Model of the Sample Applications • Tier Overview • Tiered Architecture and used Technology • MVC Patterns • Design Patterns • Modular Design (for J2EE Pet Store)

  9. Tiered Architecture and used Technology

  10. Pet Shop multi-tier: Purpose of Tiers

  11. Pet Shop: High-Level Logical Architecture

  12. General structure of a J2EE multi-tiered application

  13. Technologies used in different tiers and their functionality in J2EE Pet Store

  14. Correspondance of Tiers

  15. Presentation Tier

  16. Components in the Presentation TierComputational Viewpoint – Detail Level 0

  17. Pet Shop Presentation Tier:Computational Viewpoint of Components – Level 1

  18. Files of J2EE Pet Store Web Site Web tier

  19. Middle Tier

  20. Componentsin the Business Logic TierComputational Viewpoint – Detail Level 0

  21. Pet Shop Business Logic Tier:Computational Viewpoint of Components – IT Level

  22. Different enterprise beans in J2EE PS Web Site EJB tier

  23. Implementation of an EJB

  24. EJB in .NET? • Enterprise Services • Business Entity

  25. Data Access Layer

  26. Components in the Data Access LayerComputational Viewpoint – Detail Level 0

  27. Pet Shop Data Access Layer:Computational Viewpoint of Components – IT Level

  28. MVC Pattern

  29. Model-View-Controller Pattern

  30. Model-View-Controller Pattern:« Code behind »

  31. J2EE: Model-View-Controller and corresponding Tiers

  32. Design Patterns Design Patterns used in J2EE Pet Store Design Patterns used in .NET Pet Shop

  33. Design Patterns used in J2EE Pet Store

  34. In which tiers the Design Patterns are best implemented

  35. Design Patterns and MVC

  36. .NET Design Patterns:Design Patterns used in .NET Pet Shop

  37. .NET Design Patterns:Design Patterns in Tiers

  38. Model-View-Controller Pattern:Model-Controller separation

  39. Model-View-Controller Pattern:MVC in Controller Pattern

  40. Modular Design of J2EE Pet Store Modular development decouples components from one another benefits: • ease maintenance • simplifies parallel development • provides opportunities for incorporating third-party components

  41. J2EE Pet Store Modular Design

  42. Implementation of Control Module

  43. Implementation of Catalog Module

  44. Conclusion

  45. Conclusion • No big differences • Performance: • .NET a bit better, because efficient caching. • .NET PS fewer lines of code, but not significant. • J2EE PS not optimized for performance • Architecture: • Both are multi-tiered application with same functionality • .NET uses additional tier, business entity to track and pass data • J2EE uses enterprise beans in EJB tier
