  19. Components

  20. System Architecture • 3-tier application • Presentation layer • Bussiness logic • Database layer • Client/Server communications model • Each tier can be developed concurrently • Tiers communicate thru interfaces • Easy to change implementation of one tier without changing other tiers

  21. Presentation/Bussiness layer • Struts2 MVC • Spring, Spring security • View rendering: Tiles, Freemarker, taglib, JSON, XML

  22. Database layer • JPA/Hibernate ORM framework • Ehcache • Spring data

  23. Design patterns • One class must do one thing (decoupled as much as possible) • Tests for important parts • Use singletons when possible • Only object itself can change its state (use getters and setters) • Respect naming convention
