DESIGN PATTERNS Factory What: Why: Factory Design Pattern – creates objects without identifying the specific classes to be created DAO Factory – Data Access Object Factory Abstracts and encapsulates access to data source Why: Stored data isn’t always stored neatly using SQL Different RDBMSs, different APIs

Design Patterns Service Locator Abstracts the jndi lookups needed to create Session Bean objects, DataSources, and MessageContexts Caches EJBHome and DataSource objects so they don’t have to be recreated each time

Façade (Business Delegate) DESIGN PATTERNS Façade (Business Delegate) Hides underlying implementation details by creating a simple interface Reduces coupling between client and business services Allows for changing of business services implementation without disrupting client side code
