The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

where we say "value objects lead to code duplication" from the following?

Asked by she1 in Java Programming Language, Enterprise Java Beans (EJB)

Tags: value, object, hibernate

Entity EJBs fall short—Entity EJBs are not as flexible or feature-rich as other
ORM tools. Spring recognizes there are some great ORM tools out there,
such as Hibernate and JDO, and provides a rich framework for integrating
them into your application. And since an entity bean could represent a
remote object, the Value Object pattern was introduced to pass data to and
from the EJB tier in a course-grained object. But value objects lead to code
duplication—you write each persistent property twice: once in the entity
bean and once in your value object. Using Spring together with Hibernate
or another ORM framework, your application’s entity objects are not directly
coupled with their persistence mechanism. This makes them light enough
to be passed across application tiers.
