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!

GUI and database connection strategy

Asked by GrandSchtroumpf in Java Programming Language

Tags: database, connection, gui

I have a Swing application that uses a database for storage (using database abstraction).

What should I do with my connection?
Should I keep it connected until the GUI exits?
Should I create a new one each time I need to access the database and close it when i'm done?
Should I use a timeout and close the connection when it expires if no other database access has been requested?
Do I have other options?

Also, my db server (firebird 1.5) uses additional memory each time an update statement is executed.
The memory is only released when the connection is closed.  When there is no more available memory, the server complains.
Is there a way to force the db server to release that memory without needing to close the connection?
Currently, I count the number of sql statements.  When I'm done executing all current statements, I check the counter and close the connection if the counter reached some arbitrary maximum value...  That works, but it's not ideal.

Note:  My database abstraction is also used by a batch processing program that should only need to close the connection when the batch is all processed.  I guess I will need to have 2 different modes, one for GUI and one for batch, but that should not be a problem.

What do you think is the best strategy?
