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!

Slowly Changing Fact Table?

Asked by jahworld in Data Mining, Databases Miscellaneous, OLAP

Looking for a some ideas:

I work for transportation company, and I'm building an EDW from scratch.  The first segment of the EDW is that they want to track passenger:  Reservations, Ticket Purchases, Actual Trip, Closed (refunded or reissued).  These are looked at in the organization as separate entities, but in reality they are simply different "stages" of the passenger.  These stages share about 85% of data elements and 90% of dimensions.

The issue that I'm struggling with is that as the reservation moves through the stages, there are more data elements, more measures and more dimensions.

Therefore, if I put them in one cube, this would cause a significant number of "Unknown" members in dimensions and zero value measures for the earlier stages as these won't be "complete" until reaching the final stages.

I know I create measure groups for the different stages, but on the dimension side?

My instincts are the they are so similar that they should be one cube, but the perfectionist in me is struggling with the empty members.

Since I don't have anyone here to expand the idea with, I thought I would come here.  Any thoughts you might have could spur some innovative thinking!!  Look forward to hearing from you...
