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
Hi, I am using Sql 7.0 with sp2. I just started as a sql dba. I have a question here, What is the importance of SID's ? When we are mapping to sql logins and user_id 's how we have to give importance regarding SID's. Pls suggest me a good article or some suggestions...
Hi all-- there is a file in C:Program FilesMicrosoft SQL ServerMSSQLBinn direcetory called sqlctr.h which contains a lot of counter parametres..could any one tell me having its importance and can we change any of parametres to gain performance.. Thanks in advance..

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
y y
y y
y y
y y
y y
y y
y y
y y
y y
y y
y y
y y
y y
y y
n y
n y
n y
n y
n 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?
hi, 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.
Is 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')
Can anyone tell me, how the Business Ã?ntelligence Studio calculates the importance of a rule. I can't find the formula. I know some formulas, but the result in SQL Server is completly different.
Those of you who have installed SQL Server 2005 may have noticed that the installation creates several new Windows groups on the server. Do not underestimate the importance of these groups.
I 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?
During 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.
We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.
I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.
Is there any additional step I should/could take to get this active?
I have had this issue just pop up. I have local users who can connect fine, but my users that require connection by VPN cannot connect. I get the server not available or access denied error. I did confirm that the VPN'ers are connected to the network correctly and can see that their shares and mappings are correct. Any ideas? Thanking you all in advance!!
I am trying to revert back to Windows 7 after upgrading to Windows 10, however it will not let me and the following message occurs: "Remove new accounts.Before you can go back to a previous version of Windows, you'll need to remove any user accounts you added after the most recent upgrade. The accounts need to be completely removed, including their profiles.You created one account (NT SERVICEMSSQLSERVER) Go to Settings> Accounts> Other users to remove these accounts and then try again".However I did not create any new users and there are no other users listed in the Accounts section.
hi alli've got two tables called "webusers" (id, name, fk_country) and "countries" (id, name) at the meantime, i've a search-page where i can fill a form to search users. in the dropdown to select the country i included an option which is called "all countries". now the problem is: how can i make a stored procedure that makes a restriction to the fk_country depending on the submitted fk_country parameter?it should be something like SELECT * FROM webusers(if @fk_country > 0, which is the value for "all countries"){ WHERE fk_country = @fk_country} who has an idea how to solve this problem?
I have moved several SQL 7 databases from one server to another. The databases are attached, and I can see all the tables,etc. However, I can only see 1 user, that being dbo, therefore users cannot log into the db. HELP
I'm using SQL 2000 and I'm the database owner. I have been running tests with stored procedures to add logins, revoke logins, add db access, revoke db access etc.
Now I can't seem to add users to the database. I've tried using 'dbo' and 'domainmy_username' but I'm denied permission to run any stored procedures to try and add myself to the db_accessadmin or sysadmin roles.
I've tried the New Database User dialog and choose <new> under login name. I browse for the user name on my domain, click OK, and I get the message 'You must be logged in as 'sa' or a member of sysadmin or securityadmin to perform this operation.'
I thought the dbo always had full permissions on his database. This doesn't make sense to me. :confused:
The only thing I can figure is my permissions have been revoked on the master db.

My database is being moved from SQL 2000 to SQL 2005. Is there a way to copy a User from the old database to the new one, call it a different name and let it have all the same rights as the old one.
I am using sql server express edition. I have centralised database running in windows XP home edtion version. I can connect only 5 clinet computers at a time to the main database.

Hello, I am new to this forum, and ASP .NET 2.0. I watched the tutorial on how to use the login control with SQL Server 2005 Express, and was able to duplicate it easily. However, I tried to see if I could do the same thing with SQL Server 2005 that is hosted by my hosting company, and I was unable to get it to work. I am using Visual Web Developer 2005 Express, at least until I get VS 2005 in a few weeks, and I am able to connect to the SQL Server. I tried following the tutorial on this site step by step, and some of the things they used to set it up I could not use. In the tutorial VWD creates the table automatically. If I use the hosted database, do I need to create the table, or is there a way for VWD to do it that I haven't figured out yet. Any help and additional information that I might need to know would be great. Thank you for your help. Ben
I recently moved my .NET project out to production, the server is Windows 2003 running SQL 2005. My developement server was a Windows XP running SQL 2005. Here is my issue. Under development I created a specific user to log in as, created a role and specified exactly what application specific stored procedures etc. that user was allowed access to. Everything worked fine. Backing that database up and restoring it to the new server, when I attempt to log in as the user (and yes I re-created the login, with the user, just as I did on the development server), I get this error... EXECUTE permission denied on object 'aspnet_CheckSchemaVersion', database 'MoldKit', schema 'dbo'. So I attempt to login as SA, and everything works... so I assign the db_owner role to my user and login, everything works... problem being they shouldn't be db_owner. And they're most definitely not assigned this role on development. I even went so far as to delete the database, and recreate it from scratch using the aspnet_regsql.exe and I get the same error. Anyone have any idea why this is happening, or the proper roles I need to assign so the user isn't a dbo, but can still call all the required aspnet procedures. Or could this be some other issue caused by 2003? I've seen this error in a lot of posts, but never once saw a definiative answer to what causes it and and what the fix is.
Hi there, When conecting to a MS SQL Server 2005, I could define in my connection string Windows Authentication. What account it will be used? The one used by IIS (I still don't know the user ASP.net runs, if it is independent of IIS or not)? And if I whant that some aspx pages have diferente acess rights? I need to use SQL Server Authentication with diferent users created in MS SQL Server right? In ASP.net, what is best practice: Have one SQL account, and make users access rights in Business Logic, or have different SQL Accounts por the diferent access rights I whant in every page? Sorry if this are basic questions, but In the find's I made, I saw very confusion ideas. Thanks in advance, and sorry my english. Alberto Ferreira
