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

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
