Explanation:
All non-trivial abstractions, to some degree, are leaky.
An abstraction that works most of the time, but where a detail of the underlying complexity cannot
be ignored, thus leaking complexity out of the abstraction back into the software that uses the
abstraction.

Which design pattern, if employed in the refactoring exercise, would most directly address the two
issues?

NO.6 A successful web application is used by over two hundred thousand users. Due to this
substantial load, the database is over bridged and fails frequently. All data, included critical user
records and temporary session data, is stored in the database. Because of resource constraints, a
new database system cannot be installed.
Which change will reduce the load on the database?
A. Creating more entity beans to optimize interaction wild the database
B. Refactoring the web application to use DAOs to communicate with the database
C. Refactoring the web application to store temporary session data on the web servers
D. Adding more web servers to the web tier to distribute the load and reduce the number of
transactions on the database.

TOPICS
Application Design Concepts and Principles
- Identify the effects of an object-oriented approach to system design including the effect of encapsulation, inheritance, and use of interfaces.
- Identify how the Separation of Concerns principle applies to the component model of a Java EE application; including client, the web and business component containers, and the integration and resource layers.
- Identify the correct interpretation of Separation of Concerns as it applies to the Java EE service layers, including component APIs, run-time containers, the operating system, and hardware resources.
- Identify non-functional and quality-of-service requirements that influence application design, including trade-offs in performance, availability, and serviceability.
Common Architectures
- Identify the appropriate strategy for deploying client applications to desktop and mobile platforms, the principles for designing a user interface and the benefits of applying client-tier patterns.
- Identify best practices for exception handling, logging, and business tier patterns.
- Identify design patterns that address specific challenges in the web tier, including authentication, authorization, and scaling and clustering to meet demand.
- Identify Java EE technologies, including JMS, JCA and Web Services, and design patterns that address specific challenges in enterprise integration.
- Identify the challenges in integrating enterprise resources, the Java EE technologies that address them (including JPA and JDBC), and the communication protocols that support tier-to-tier communication (including RMI, IIOP, and CORBA).
Integration and Messaging
- Identify the APIs available for a Java EE technology-based system to communicating with external resources, including JPA, JDBC, RMI, Web Services, JMS, and JCA. Outline the benefits and drawbacks of each approach.
