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.

Database for 20,000 users - a few optimalization questions

Asked by wilq32 in Massive Multiple Online Role Playing and Other Online Games, Databases Miscellaneous, MySQL Server

Tags: SQL, MySql

I am designing a big Web application - Massive Multiplayer Online Game for around 20.000 players, and I got a few designers question. I'm not need any source code, or solutions, just a few words of optimalization ideas. Here are mine actual problems:

1. I would like to store information about Players Items. Every player could have around 100 items, so the question is: Is this wise to make one table for items of structure like this:

ItemID, OwnerID, Parameters (few - 5 or 6).

And to make ItemID an Primary Key. Is there any better sollution? Does 100*20,000 = 2,000,000 records in table is not too much for database (MySQL) ?? How much time does it takes normally to search all table for items from OwnerID? What do you propose to make it working fast?

2. This question is related to 1. one. Some time ago I thinking about a solution for this problem to make table for every user that i register in system. But I never saw that type of solution in working Application so my question is - Why ? Why noone do that? Is this worse than storing everything in one table? I need to store items for every user, but I dont need to have them all in one table.

3. This will be last question for this problem. I would like to know if in mine case working with files (for storing Items) would be better that using database?


Thanks for any help!
