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!

J2EE Architecture for reporting tool?

Asked by paku in Software/Systems Design

Hi

We are developing a reporting tool. The tool has filter page where we defines all the filters like text box, checkbox,date range,list box etc.
Also on the same filter page we have box containing the Available field list. User can select the fields from available field list and the selected fields
will be diplayed on the next screen. The filter page has three text box where user can select values from the selected fields for sorting of records in desire way.
The selected filters will be used to prepare whereClause of the query.Selected fields will be used to prepare the selectClause.
Next page from Filter page where the records display has three section Top, Middle and bottom. Middle and bottom section will be refreshed after Top section query exectues and records display on the screen.
The query may have MAX() based on the display field selection.

For above requirement I am planning to use the following architecture.

JSP --> ActionServlet --> Service Layer --> DAO layer --> Database.

Is this correct selection or should i need to add some more layers to reduce tight coupling.
