Product Basket Problem
Aug 9, 2006
Hi,
I have to build a Poduct basket mining mode
Hi,
I have to build a Product basket mining mode such that when a customer selects
a product the model should be able to recommend him/her some more products.
I have a customer, product transaction table.
I have come across many typical examples where the output is
as follows
Customer Recommended Products
Cust1 a, b, c¦¦.
Cust2 e, b,
f¦¦¦.
But I want the output of the model to be as follows
Product RecommendedProducts
A B, C, D¦¦.
B E, D, A¦¦.
C D, A, F¦¦
How should my mining model structure and the prediction
query look like?

Hi!
I have a problem. I would like to make Market basket analysis on data.
Here is the example of data structure:
Customers
Customer_ID
Gender
Age
City
CustomerProducts
Customer_ID
Product_ID
I've created mining association model where Customers is a case table and CustomerProducts is nested table.
(I guess that association algorithm is the best for this kind of analysis).
My questions are:
1. How to write DMX query for next question:
Give me the list of customers that are using Products R1, R2, ... Rn and have potential to buy Product Ri
(List of customers with probabilities to buy Ri)
2. DMX query for next:
Same as 1. but customers filtered by some criteria, for example Gender = 'M' and Age between 25 and 36
3. DMX query for next
For chosen product Ri give me the list of groups of products with probabilities that customers that are using products from that group will buy product Ri.
(here is the example: for product Ri list will have to look like this:
R2, R5, R6 0.85
R5, R7 0.76
R1, R4, R5, R8 0.75
...
)
I don't know does this report have sense since customers that own products from one group have different other attribute values (Gender: M, F; Age...) but I have request like that...
Thanks in advance

Can someone please help me with this? I am trying to do a Market Basket Analysis with this kind of data, which can be downloaded here-- filename: foodmart.mdb (https://acs.senecac.on.ca/ftp/ms/). Using the sales_fact_1998 table, I'd like to:
1) Run a "regular" SQL query
2) Run a SQL theory using the "A-Priori" method.
If anyone of you can help me, I would greatly appreciate it. Thanks.

I'm looking for suggestions on the right design approach in relation to a problem that resembles Basket analysis. The data to be analyzed is a dimension Attribute_DIM and contains an ID, Attribute and Attribute_Value. Some examples of the data are :
ID Attribute Attribute_Value
1 Color Black
1 Movie Men in Black
1 Book Of Human Bondage
2 Color White
2 Movie Men in Black
2 Book Grapes of Wrath
We need to be able to analyze multiple selections of the dimension. For example,
Men In Black
Grapes Of Wrath Of Human Bondage
Men In Black Black 1 1
White 1 0
I have had some success using the Association Algorithm Mining Model. I think It is an overkill since I only need descriptive and no predictive analysis.
I'm looking for some ideas on the right approach to this problem. Ideally, we need to present the data in a cube and have the possibility to perform member analysis of the dimension.
I have looked at several articles (including http://msdn2.microsoft.com/en-us/library/aa902637(sql.80).aspx and http://www.aspnetpro.net/newsletterarticle/2004/10/asp200410ri_l/asp200410ri_l.asp). I'm not convinced those are the solutions and would appreciate any insight into this problem.
Thank you,
Anna.

I want to upgrade 5 SQL Server 6.5 production boxes to SQL Server 7. I got
SQL Server 7.0 pricing and licensing list from
www.microsoft.com/sql/70/gen/pricing.htm and I think I should buy 5 SQL
Server 7.0 Combined Product/Version/Competitive Upgrade (Since I have been using SQL Server 6.5, I dont need to buy the full product. Is this right?). I am not sure if
the upgrade offer (the price is much lower than the full product offer $699/$1399) includes the SQL Server 7.0 both software and access license.
Thanks for any help in advance.

Hi,
I am interested in opinions on the following,
main(product_id, short_text, price, type)
productTypes(type_id, type)
productTables(type_id, tableName)
productA(product_id, field1, field2)
productB(product_id, field1, field2)
To retrieve all products of type 'A', one must know the table name, in this case 'productA'.
Here is one method.
Create a table that contains the table name that corresponds to each product type, thus the stored procedure only needs to recieve the type_id which can be used to obtain the name of the respective table.

I am installing SQL Server x64 on a new server, and I was told to use the same license key we have for the other servers... but no one seems to know where it is. Is there any way I could see the license key for one of the working boxes so I could put it on the new one?
Thanks,

How can the licensing product key with which SQL Server is installed be replaced/updated?
If this is possible, will the same procedure apply both to SQL Server 2000 and SQL Server 2005?

We are building a system that has mobile clients (laptop with XP and tablet with XP). These clients have data moving back and forth to a centralised n-tier server based system. The communications is proprietory and are very low bandwidth (5 KByte/sec).
We've decided that the best approach to handling both the reference data (ranging from trivial to a complex list of items - about 2 million rows) and the day-to-day operational data is with a database product rather than attempting to handle it ourselves within code.
The question is - what SQL platform to use? SQL Everywhere seems to be a fairly good choice except that it does not seem to support stored procedures. SQL Express is another possibility but there are concerns about the size of the footprint and managing the database engine and the database itself.
The users of the mobile client are considered computer illiterate and would not be able to manage any database administrative tasks. They only come back to base every three to six months. History has shown remote management of the machine has proven difficult (if not impossible) via the low bandwidth connection.
The machines have 512MB of RAM and only 40GB of disk. They have to support XP, Office, our client, and our GIS client. What is the best answer?
Traditionally we would have used MSDE.
Regards
Paul

I have a search box on my website which is used to search the products database.
I will be using the search text in an SQL stored procedure that uses LIKE statements. The search string could realistically contain any character.
How do I prevent SQL injection when any search string is reasonably feasible? .

Hi guys,
Does anybody know a convenient way to return the product of a column, similar to something like the 'sum' function?
If I have a table of form id-date-value, I'd like to do something like:
select id, date, product(val)
If not, does anyone know of a way one could structure this as a subquery?
If all else fails, I suppose I'll have to resort to a loop or cursor, but I'd rather not.
Any help would be much appreciated.

I have a SQL statement with two left outer joins which connects 3 tables. Vendors, Tracking & Activity. For whatever reason, even though each is a one-to-many relationship, I am able to join 2 tables (from Vendors to Tracking) without an issue. when I then join Activity, I get a Cartesian product.I suspected that 'DISTINCT'.
SELECT DISTINCT CASE
WHEN `vendor`.`companyname` IS NULL then 'No Company Assigned'
ELSE `vendor`.`companyname`
END AS companyNameSQL, `tracking`.`pkgTracking`, CASE

Steve writes "Probably not a tough question if I wasn't a newbie:
I have two copies of MSSQL 2005 standard edition, intended for installation on a dual proc db server. The server is physically placed in a remote hosting service.
Since I need to install remotely, it's non-trivial how to get the bits over there. I could fed-ex the CDs to the hosting service and have them feed the machine.
However they suggested that they simply use their MSDN version, which I accepted.
But it turns out the MSDN version setup has a pre-populated product key, and does not allow me to entire my own product key(s).
So the questions:
1) besides the product key thing, is there any difference between the MSDN version and the retail version?
2) does it matter that I enter my product key(s) during installation, or do I need to simply posess the keys to be legit?
3) On a dual-proc system, must two keys entered to activate operation on each processor?
So in general, I'm confused as to the technical dependence of installation on the product keys. After $12k I kinda want to use them."

Hi,I've run into a bit of a sticky design issue. We have products inthree categories which I will call 'A', 'B' and 'C'. We have "kits"which contain three products, one from each category.Below is some sample SQL to set things up, but I need to ensure thateach kit gets three products -- one from each category. Obviously,this basic SQL doesn't allow that. Any suggestions? Do I need adifferent schema design, or is there something else I should belooking at?Cheers,CurtisCREATE TABLE category (id int identity primary key,name varchar(30));CREATE TABLE products (id int identity primary key,name varchar(30),category_id int references category(id));CREATE TABLE kits (id int identity primary key,name varchar(30));CREATE TABLE kit_products (kit_id int references kits(id),product_id int references products(id));

The above link says the pros and cons of two SQL Server 2005 editions.
Document says Compact Edition is not good for When you need a multi-user database server
.
What is the meaning of multi-user database?
Does this means the database strictly will not support two database connections at a time?
-Thank you,

We are trying to setup a Virtual Machine for our developers and would like to put SQL Server 2014 (Developer Edition)pre-installed. Each of our devs have their own MSDN accounts so they would have access to their own installers / product keys.So, two questions:How do we pre-install it without a product key or install it then remove the product key?How can they change the product key once they boot up?

I am receiving the following error when I try to execute an SSIS package that is saved to a structured file. I am using DTExec to execute the package.
Description: The task "Initialize Variables" cannot run on this edition of Integration Services. It requires a higher level edition.
After some research, I was able to find a supporting article in SQL Server 2005 BOL at http://msdn2.microsoft.com/en-us/library/aa337371.aspx
The issue was resolved by installing the Enterprise Edition of SQL Server Integration Services (Windows Service) on the local server (server where the package is saved and executed from). However, this goes against my original anticipation that the SSIS Windows Service would only need to be installed on a machine where I needed to store packages and/or monitor package execution. Not if I wanted to execute packages.
Unfortunately, my package is using advanced options (as identified in the BOL article previously referenced).
Am I missing something??
Sincerely,
Sean Fitzgerald
