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!

Design of Database Connections

Asked by pralteb in MySQL Server, Databases Miscellaneous, Software/Systems Design

Tags: , , ,

I am developing a small-scale three-tier client-server database application.  The multi-threaded server is written in C with Pthreads on Linux and uses a MySQL 5.1 database with InnoDB storage engine.  It creates a short-lived handler thread for each client request.  The number of users will be small (< 100) and database operations will be brief, simple and relatively infrequent (compared to a busy website).

My question is that I am confused about the design of database connections from the server application.  Do I have one database connection that is used by all application threads or one connection per application thread or what?  At the moment I open a single connection on application startup but I am wondering whether this is going to fail when I test it with multiple concurrent users.  I know that the overhead for a MySQL connection is quite small, and I know I don't need pooling for these small volumes, but I can't find much more information to help me design this.

Can someone please clarify?Start Free Trial
