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! |

Hi,
I have data like below.
MODEL PRICE START_DATE_ACTIVE END_DATE_ACTIVE
SONY 100 1/1/1901 12/31/2005
SONY 200 1/1/2006 12/31/2007
SONY 300 1/1/2008 12/31/2008
SONY 400 2/1/2008 12/31/2009
SONY 500 1/1/2009 12/31/2010
The above the model SONY is having the price range that depends on the start_date_active and end_date_active column. For example in the first row, the model SONY price is 100 from 1/1/2006 to 12/31/2007. The same model SONY price is 200 from 1/1/2008 to 12/31/2008. So the model price will come like this. But in some cases the date will be overlapping. See the row number 3 and 4. I should remove the rownumber 4. How can i remove the overlapping date data?
Thanks
