Explaining Importance To End Users
Jul 17, 2007Hello Experts at Microsoft.
I am thinking of an easy way to explain importance to Marketers without going into the math. This is what i came up with so far. Does this sound correct to you guys?
Reasoning:
IMPORTANCE = Log(Improvement)
Improvement=P(X&Y)/(P(x)*P(y))
Improvement= (Probability 2 products are sold together)/(random chance 2 products are sold together)
If the (Probability 2 products are sold together) = (random chance 2 products are sold together) then Improvement=1. The log(1) = 0
IMPORTANCE SCORE
-2 to -1 10 to 100 times less likely than random chance
-1 to 0 0 to 10 times less likely than random chance
0 to 1 0 to 10 times more likely than random chance
1 to 2 10 to 100 times more likely than random chance
2 to 3 100 to 1000 times more likely than random chance
3 to 4 1000 to 10000 times more likely than random chance
4 to 5 10000 to 100000 times more likely than random chance
5 to 6 100000 to 1000000 times more likely than random chance
6 to 7 1000000 to 10000000 times more likely than random chance
Association Rules - Importance
Feb 14, 2008
I understand Mr. MacLennan's explanation provided at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=282651&SiteID=1 and appreciate the time he took to explain how importance works. However, like the user with username "sang", I also ran the data in BI 2005 and got the same results listed by the aforementioned user. I did this using the following data:
donut
muffin
y
y

etc.
The rule muffin -> donut has an importance of -0.105302438, which is not the same as Mr. MacLennan's results. I tried switching the roles of a and b in a -> b and using different bases on the logarithms. I don't get the result of -0.105302438 with any of these. I also tried to calculate importance with a small data set I have and can't get the results using Mr. MacLennan's explanation with that data set either. Any thoughts on the descrepancy?
The Mean Of Using Association With Importance And Probability
Apr 12, 2007hi,
i have a exercise using association datamining
my database have 350 records,
i use 90 records for datamining and it release some rules which i choose on top of mSOLAP_NODE_SCORE,
but when i use select statement to check my result i have 1 records, the same as my result, and 5 records not true;
for example:
rules A=a,B=b-> C=c
select * from <my_table> where A='a' and B='b' and C='c'; ==>1 record return
select * from <my_table> where A='a' and B='b' and C<>'c'; ==>5 records return
C with 3 values c1,c2,c
with the second statement C includes 2 c1 and 3 c2
i don't understand how they work.
i want to choose some best rules can present my database.
how can i choose importance and probability to get best rules.
with database have 90 records and a database have 350 records which values i should use for minimum_probability, Minimum_Support, Minimum_importance...
when i choose rules i should choose on importance or probability.
thanks for your help
Attribute 'importance' Factor
Jan 31, 2008Is there a way to explicitly assign 'weights' or 'importance' factors to attributes and have that to be considered by the association rules and decision trees algorithms during training? I would like to do so without preprocessing the data (In any case, I can't think on a way to assign weight with preprocessing to boolean attributes like 'smoker')
thanks

Unique Columns In Sort By Importance Result
Dec 30, 2004I try to search my data and sort the result by importance.
I'm using a MS Access database and my data (table1) looks like this:
Code:
ID NAME TEXT
1 Apples Good red apples
2 Bananas Fine yellow bananas
3 Yellow apples Great yellow apples
I want to search the data and get a result where the column "NAME" is more important than "TEXT". My SQL looks like this:
Code:
SELECT id,name,text,1 AS searchorder FROM table1 WHERE name LIKE '*yellow*'
UNION
SELECT id,name,text,2 AS searchorder FROM table1 WHERE text LIKE '*yellow*'
ORDER BY searchorder
The output is this:
Code:
ID NAME TEXT SEARCHORDER
3 Yellow apples Great yellow apples 1
2 Bananas Fine yellow bananas 2
3 Yellow apples Great yellow apples 2
So far so good - the order by importance works - but I do not get unique columns because of the searchorder column.
Can I fix my SQL so I get unique columns where the last line of "Yellow apples" does not appear or am I lost in space?
Best regards,
Peter from Denmark
Slowness In SSIS Package And The Importance Of Disk Maintenance
Sep 22, 2006During testing a package repetatively that deletes/inserts into several tables, over the course of several days, my package, which took 45 minutes to load 1700 XML files, began to take over 6 hours. Turns out it was an I/O bottleneck, and the Avg Disk Queue Length was around 200 and I was incurring many PAGEIOLATCH_EX. My devl machine uses a single local disk, no raid, so I had no options there, but I ran the maintenance wizard to recreate indexes/statistics and defraged the hard drive, and regained my original 45 minutes time. I guess I'll have to put a maintenance plan together to do this nightly.

Multiple Triggers On A Table Or Encapsulated Triggers
May 12, 2008This isn€™t an problem as such, it€™s more of a debate.
If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

SQL SERVER TRIGGERS
Oct 3, 2006Hi Guys,I have a website that has a log in box, when a user logs in it automatically inserts a 1 in my users table and a little icon changes color on the web page to indicate that a person is signed in, my problem is that sometimes my users don't log off using the signout button which then puts a zero back in my table and a different coloured icon is shown. I cant seem to force them to use this button so I being new to sql server wondered if I could use a trigger to set the field to 0 after say half an hour.I also have a table that has various projects in it and they each have a field that has an estimated end date, I wondered if there was some sort of trigger I could use to fire off an email when the todays date passes that end date to notify evryone it was overdue. If this can be done please could you provide me with an example, Many thanks

SQL Server Newbie (Triggers)
Jul 31, 2000Good afternoon one and all,
I am migrating a access dbase to SQL. I have two tables, the first is a buffer table that collects data from various sources, the second table is an indexed version of the first table (to eliminate duplicate records etc. etc.)
I am currently using the DTS packaage to transfer data between them, would a trigger be a better solution?
Thanks in advance for any and all help

Triggers Using SQL Server Functions
Apr 12, 2007Hi,
I am still learning the bells and whistles of SQL Server and was wondering if I can find out the query that caused my trigger to fire, so that I can log this in another audit table.
I have an If Update ( My_Column ) trigger set up, where once an update happens to My_Column much information from the updated row along with , Host_Name and App_Name is sent. I also want to send the exact query used to update it, any ideas?
Any comments, suggestions will be greatly appreciated.

Instead Of Triggers On Views In Sql Server 2000
Oct 15, 2007hi all,
i had a view in my project, i am inserting a record in to that view(View contains a identity key for a column), with in stored procedure i am inserting a record i am not passing the identity key value to the insert statement. The record is getting inserted,Based on the identity key(i am getting the identity key value with Scope_Identity()) and with that value i am inserting records into another two tables.In this scenario every thing is working fine.
but now i am trying to place a trigger(instead of insert trigger) on the view, when i placed,it is not inserting record into first table,so i am not able to get the identity value of that record and process failed.
how can this achived, let me know.
SQL 2012 :: Triggers With Linked Server
Nov 10, 2014I have a system where people can apply for registration and also a registration fee is involved. The screen where the application is captured has a couple of inserts into different tables. Each of these tables have triggers on them to transfer data to a linked server and they work fine. Today I just added another trigger on a different table but also part of this same save process. Now I am getting the following error:
Microsoft OLE DB Provider for SQL Server error '80004005'
The statement has been terminated.

I do not know this error and think it might be time-out.
Stretching The Limits Of Triggers In SQL Server
May 1, 2008Hello all.
For my first foray into this forum I have a tricky one....
We have a table in our database called tblJob with two columns:
id IDENTITITY(1,1)
jobNbr VARCHAR (5) (This would be, for example '12323')
When a new job is created (i.e. job Number 12323), the client wants a trigger on this table that creates a new table called tblJobData12323.
Does anyone know how I can accomplish this?
Thank you in advance.

Simulating Triggers On SQL Server Mobile
Feb 24, 2007Hi,
Can anybody let me know if there are ways to programatically track changes made to a SQL SERVER CE table? I am writing a db monitoring tool on SQL server CE which should track any changes made to the table.(Insert update and delete)
We could have done this using triggers on Sql Server 2005. Since triggers are not supported on SQL Server CE, are there any alternate ways to achieve this functionality?
