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!

Organization for a task with multilevel participants

Asked by playacar in MySQL Server, PHP Scripting Language

Tags:

Hello experts,

I have the following problem: In a very large table i have like 900 thousand records with all the information like idTag, name, age and phone number  for each person participating in  a task.

The task will be done organized by a Lead an area coordinator, a helper and the participants.

Participants will sign up with a helper and can be up to to 20 participants per helper, the helper then submits its participants to the area coordinator and the coordinator submits all his helpers ( up to 50) to the lead.

I am using PHP and MySQL

I did it before using copies of the large table but the program went very very slow. So now i need help to do it again and create the right tables and the right queries.
the IdTag is a unique alphanumeric string of 18 characters.  I was thinking just to use that tag to do the table relationship but then when i print the reports I need full data from the main table and that  I think is what slows down the server as i did a query for every IdTag to get full name, phone, etc...

All participants information stays intact. The created tables contain only references to the the big table. And at the end the lead must print a report with the tree structure order to  see who participated in the task only with a yes or not mark next to each participant. The leads, coordinators and helpers are in the big table and are also participants.


Thank you in advance for any help.
