A course on applying specific Design Patterns to the development of enterprise applications that are structured on different architectural layers.
Description
This course targets programmer and architects having experience with building enterprise applications on the J2EE platform and presents the most important patterns that can be used to improve the layered design and maintainability of the developed code.
At the same time, we present some of the most common anti-patterns (frequently-used but generally bad solutions) and how to avoid them or remove them.
About 30% of the time is on guided exercises.
Contents
- Definition of the tiers of an enterprise application
- Practices for high cohesion and low coupling of the architectural tiers
- Presentation tier patterns: Intercepting Filter, Front Controller, Context Object, View Helper, Composite View
- Presentation tier anti-patterns: too much code in JSPs, navigation information in JSPs, too much session data, “Copy and Paste” JSPs; duplicating Servlet functionalities, static text in Servlets, no connection pooling, direct access to business entities
- Business tier patterns: Service Locator, Business Delegate, Session Façade, Business Object, Transfer Object, Transfer Object Assembler; handling domain objects
- Business tier anti-patterns: Bloated Session, Thin Session, Transparent Façade, Data Cache
- Designing the data access tier: mapping persistent information to domain objects
- Concurrency in enterprise applications: transaction management and related patterns
Skills you'll learn
- Learn the design principles for the correct separation of architectural layers
- Design your business tier with patterns
- Integrate your object model with relational databases
- Avoid common design mistakes
