What Are The Relationships Among The Attributes Within Each Cluster?
Dec 6, 2006
Hi, all here,
Thank you very much for your kind attention.
I am having a question about Microsoft Clustering algorithm here. When we train the clustering model, we gain the clusters based on the model training. So what are the relationship among all attributes within each cluster? When we sumarize the characteristics for each cluster, for example, based on criteria attribute A=X, we got the darker cluster for this criteria, along with this characteristics (A=X), we also got other characteristics, so what is the exact relationship among all these chracteristics? It seemed they dont have any relationship to each other at all? (A=X dose not mean most likely B=Y if A=X?, what it means only is within this cluster, most likely A=X and B=Y etc. and A=X has the largest population within this cluster). I therefore cant see these chracteristics really interested.
Looking forward to any guidance and advices for that.
With best regards,
Yours sincerely,

I am working in SQL Server Master Data Services  Version 11.0.5058.0 (SP 2).
I have been asked to group all the financial attributes together. Â When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Â Then I reach a section of attributes where it leap frogs over 24 attributes.
It appears these 24 attributes are in a subgroup but there are no attribute groups and I removed the subscription view from the entity. Â If I move one of the 24 attributes in the group, it moves it outside of the 24 attributes.
This is under leaf member attributes. Â There are no collection or consolidated groups.

I'm using a DW from Northwind database to build a cube to do some analitical taks. I already create the cube and now I am "cleaning" the dimensions. I'm having some difficults to understand the logical off this part. The reason is that When I create the Data Source View, I only import the Foreign Keys that connect the Dimensions to Fact_Table. I have to drag the attributes of Dimension from Data Source View to the tab attributes?Â
Imagine this:
I have the following dimension:
Dim_Customer:
Customer_ID
Name_Customer
Job_Function
Date_of_Birth
Contact
Address
City
Country
When I create the cube only Customer_ID appears in attributes tab, it's normal?Â
One more question:
I don't want to create a hierarchy like:
Customer ID -> Name_Customer
Customer ID -> Date_of_Birth
Customer ID -> Address
Customer ID -> City
Customer ID -> Country
My idea is to create the following hierarchy:Â
Name_Customer ->Â Date_of_Birth ->Â Â Address ->Â Â City ->Â Country
But the first hierarchy that I show is always appears to me. Do you know what is happens?

Hello all-
I have a specification table that has some attributes defined.
SpecId - Id of the specification
Attribute - Attribute of the spec. (Like Color, HP etc)
Value - Is the value of the attribute
Then I have a car table that actually has information about the cars. Intention is to take each specification and match the cars that match the specification. If the car has more attributes than the spec, we ignore the extra attributes for the match. But if the car has less attributes, we don't even consider the car as a match (even if the attributes present, match). To summarize, the car's attributes should be >= spec's attributes.
The code I have below is bad because I am joining the same tables twice. In addition, it fails in the condition "the car's attributes should be >= spec's attributes"
Any help is greatly appreciated.
DECLARE @Specification TABLE
(SpecId VARCHAR(10),
AttributeVARCHAR(100),
ValueVARCHAR(100))
DECLARE @Car TABLE

INSERT INTO @Specification VALUES ('S1', 'Type', 'Sedan')

INSERT INTO @Specification VALUES ('S1', 'HP', '220')
INSERT INTO @Specification VALUES ('S2', 'Type', 'SUV')
INSERT INTO @Specification VALUES ('S2', 'Transmission', 'Manual')
INSERT INTO @Specification VALUES ('S2', 'HP', '300')

INSERT INTO @Car VALUES ('Escape', 'HP', '300')
INSERT INTO @Car VALUES ('Explorer', 'Type', 'SUV')
INSERT INTO @Car VALUES ('Explorer', 'Transmission', 'Manual')
SELECT DISTINCT Spec.SpecId, Car.CarName
FROM @Specification Spec
INNER JOIN @Car Car
ON Spec.Attribute = Car.Attribute
AND Spec.Value = Car.Value
WHERE Spec.SpecId NOT IN (SELECT Spec.SpecId
FROM @Specification Spec
LEFT OUTER JOIN @Car Car
ON Spec.Attribute = Car.Attribute
AND Spec.Value = Car.Value
WHERE Car.CarName IS NULL)

I am using db keyowrds as attributes in my table such as from, to and date. These are enclosed in [] in SQL Server Enterprise Manager. I'm just asking if doing this is a bad idea? Reason being these are the most applicable names for these attributes but don't want to run into problems further down the line.

Have a report that I want to keep certain attributes and as long as the report contains this certain attribute, bring all other attributes with it. Better with an example. In this report I am specifically looking for attribute "Alcohol", if I find this attribute I want to include all others that fit with this record's Primary Key which could include, "Drugs","Arson","Vandalism", etc. Problem is when I try to use a paramater or filter I get the "Alcohol" Attribute but not the "Drugs","Arson","Vandalism", etc. Conversely since I dont have any filter/paramater set I get everything even if it does not include "Alcohol"
suggestions??
thansk in advance

Bit of a design question as I'm interested to know if anyone's done anythign like this...This is my main table (ish) Thing(ThingId, Ref)I then need to be able to give this "Thing" any number of attributes. Thing1 - Type:Red, Location:LondonThing2 - Type:Blue, Height:400, Width: 300Thing3 - Height:500, Location:Norwich But I have no idea how to model this in the database - it needs to be in such a way that I can add a Thing and all its attributes in one database hit basically (is there a stored procedure you could pass an array into?) My initial thoughts were to have Thing(ThingId, Ref) Attribute(AttributeId, ThingId*, AttributeTypeId*, Value) AttributeType(AttributeTypeId, Description) Is that completely mad? It seems like quite a lot of data accesses to enter a ThingIt could be Thing(ThingId, Ref, Type, Location, Height, Width) but then when "Thing - Color:White" comes along the model is stuffed Any ideas? (hope that makes sense)

In query analyzer, what is the command to tell me the attributes of the entities in a table? In oracle I can use the describe command. I know their is a way to do it in Query analyzer but I can't remember how. Also I can look visually by expanding the node of the table. But if I can do this through the command line in query analayzer, it is sometimes quicker.
Example. I want to find out about a table named "Employee"
What command would I type that would tell me all of the columns/attributes in that table, and the data types which they are?

I have a few tables that have an disabled attribute using a BIT datatype. A lot of my queries on the front end look like:
SELECT *
FROM TableA
WHERE disabled <> 1
There's usually some other constraints on the query (get TOP 10 and greater than a certain date for example). Right now my tables are very small (only a couple thousand rows). I don't anticipate these tables having more than 100,000 rows.
Right now let's say there's only a CLUSTERED INDEX on the date field, and regular INDEXES on the identity field and perhaps some other UNIQUE name in the table.
Unless I am doing ranged queries on the CLUSTERED INDEXED field, I'm going to be performing table scans almost every time, right?
This sort of goes along with another question:
Say you run the following (SQL Server):
CREATE TABLE TestA (
[id] INT IDENTITY (1, 1) PRIMARY KEY,
disabled BIT DEFAULT 0
)
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
Since [id] is a PK there will be a CLUSTERED INDEX placed on it. My question is; what does the optimizer do when you perform the following query?
SELECT TOP 3 *
FROM TestA
WHERE disabled <> '1'
My assumption is that since there's a CLUSTERED INDEX it will simply iterate through every tuple and check to see if disabled is not '1'. If my assumption is correct then these kind of boolean fields aren't a big deal if TOP queries are performed on a CLUSTERED INDEX.
So I guess what I am getting at is: Are bit attributes a sign of bad design? As tables get larger will performance degrade significantly? Would a better design be to have a seperate table of disabled items (which may result in large NOT IN subqueries)?
Any information on his would be greatly appreciated.

I have a question about storing the history of particular objects in a database. For example, if I had a table of "People" which had fields "PersonId", "Name", "PhoneNumber", "Height", "Weight", "Proffession" the data in every field stored for each person can change over time, except for the "PersonId", of course, which is why it is included.
I would like to be able to view a persons attributes at any point in time and therefore need to maintain a history. The currenct approach in place is to archive images of the whole table at certain points in time, which is unacceptable as it misses some changes, is not very accessible and also stores data which does not change.
My solution would be to created seperate tables for each changing attribute and have corresponding date for each change. For example, for phone numbers have a table "PeoplePhoneNumbers" with fields "PersonId","PhoneNumber" and "ChangeDate". A few shortcomings I can see in this approach is that firstly there will be many tables, one for each changing attribute, which can be in far greater number than those mentioned. Secondly, joins will have to created between every attribute table to get the orignal single table form, although I don't see this as a very important issue.
I am wondering; is there a more elegent way to structure for objects of this changing nature, or is having seperate tables for each changing attribute the best solution? I'm sure this is a very common issue. Thanks very much for the help,
Mike

What are attributes in columns that are not types?

We have an entity such as a documentSearchKey that contains attribtes about a particular document. This document can have 1-N number of search keys or attributes. The classic Employee Table is a good example for a horizontal listing of attributes (fname, lname, SS#, address, etc.) because the employee entity has a "fixed" number of attributes so we can add columns across.
For the documentSearchKey entity attributes can be considered search keys or where clause values.
The documentSearchKey entity has variable number of attributes (docType A has 5 keys, docType B has 15 keys, etc) For this example each docType lives inside its on table so there is not a problem with mixing a variable number attributes inside the same table i.e. we will assume this table has 20 keys vertical or 20 columns horizontal as defined below.
The problem is whether or not to add 20 columns across or to add 3 columns and create a non-normalized DB so additional keys can be added at will.
The proposed table now contains 3 columns (docID, KeyID, KeyValue). Of course, 10 keys for 1 million records create 10 million rows Versus the traditional table with 1 million records always has 1 million records(keys are cols) where some columns contain blanks or nulls.
Which design is better in terms of searching and performance?
Also, books and links are welcome as well. This is a specific question to a production issue.
Thank You Very Much !

I apologize ahead of time for the long post...Background:Working on a CRM type custom application. The application is for anevent management company. The company will provide the application forother organizations to manage their own events. The events includeconferences, corp meetings, sales meetings, etc...An event planner will define what information is needed for an attendeeto register for an event. We will be providing a standard list ofattributes for the event planner to select from. This list includespersonal information (name, address, phone numbers), air travelinformation (preferred carriers, departure airports, etc...), hotelinformation, etc...we've included all of the information available tous from the business's previous experience. As far as the databasegoes, all of the standard information given to use will be normalized.The problem is each event may have unique information that needs to becollected that is not part of the standard list of attributes. Forexample, if McBurgers is planning an event, the event planner may wantto collect an attendee's McBurger employee code.Depending on the uniqueness of the event, there may be up to 200 uniqueattributes defined for it. This number comes from researching eventsplanned in the last 5 years. The number of attendees for an event rangefrom 100 to 10,000. The company expects about 3000 events per year.Database DesignI've done a fair amount of research and found a couple of options tomeet our requirements, more specifically the need for event planners todefine custom attributes for an event.1-)DynamicColumns:Add an Event specific custom attributes table. The table would looksomething like this:Event_McBurger05AttendeeID | McBurgerEmployeeCode | HiredDate | SomeOtherAttribute-Join Bytes! | AxEt356 | 01/01/2004 | Other val 22-)EAV:Add an EAV (entity, attribute, value) table. The table would looksomething like this:Event_AttributesEventCode | AttendeeID | Attribute | Value-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | HiredDate | 01/01/2004McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2The Value attribute would be a character (probably varchar) datatype.3-)Stronger Typed EAVHave an EAV table for each data type. The tables would look somethinglike this:Event_CharAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2Event_DateAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | HiredDate | 01/01/2004There would be one Event_[DataType]Attribute table for each of thedatatypes allowed.Pros/Cons1-)DynamicColumnsPros:-Data integrity can be enforced-Simpler queries for reporting-Clearer data model for understanding data storedCons:-Row size limitation of 8k must be managed (probably need to addanother table if run out of room.-Stored procedures for CRUD operations would need to dynamicallycreated ORNeed to use dynamic SQL on the database or application.-Adding/Removing columns on the fly can be very error prone2-)EAVPros-Static CRUD stored procsCons-No data integrity-Complex queries for reporting-Worse performance than option 1.-Table can get BIG...fast.3-)Stronger Typed EAVPros-Static CRUD stored procs-Better data type integrity than EAVCons-Complex queries for reporting-Worse performance than option 1-Table can get BIG...fast.If you are still reading this...thank you!The Questions:-Are there other options other than the 3 described above? Or are thesepretty much it with slight variants.-Does anyone see any missing Pros/Cons for any of the options thatshould be considered?-Is there a "preferred" method for what I am trying to do?I suspect this will come down to the lesser of three devils. Justtrying to figure out which of the three it is.We have prototyped the three options and are leaning towards option 1and 3.Any comments/suggestions are appreciated.Thx

FROM [Adventure Works]
WHERE ( [Measures].[Reseller Sales Amount] )
Can someone please explain me why I'm getting this result:
All Periods

and also if anyone knows of a possible way of getting the second type of result?
please note that if I create a custom member that aggregates members of any other level of the Product Category hierarchy, the problem doesn't exist (see code and results below)

Hi,
I am a novice data miner, working primarly in the BI field. I want to learn more about Data Mining so I am doing some experimenting.
I have a question regarding input attributes. I am particurlary wondering about the Neural Network algorithm, but also for Data Mining in general. What I am thinking about is if, and if so to what extend, I should create derived attributes for the algoritms. I´ll try to clarify with an example:
Lets say I am analysing sales performance for departments in a large company. Some of those departments has a high staff turnover, which might affect sales negatively (although I don't know that...). The high staff turnover could be detected, by the algorithm and humans, by looking at each sales, and which salesperson that handled it. If there are a lot more different salespersons in different departments by the same size and during the same time period, this is a sign of a high staff turnover.
Now is this info enough for the algorithm? Or should I add a column in the case dataset, where I discretesize the staff turnover as "High,Medium,Low"? Does this help the algorithm or can it affect the performance?
I hope you'll get the idea of my question, otherwise ask me!
Cheers,
AL

This is kind of tricky. I have a table that is structured like this (where the StaffID is the primary key):
StaffID, Date1, Amount1, Date2, Amount2, Date3, Amount3
123, 1/1/08, 100, 2/1/08, 200, 3/1/08, 300
You can already see that whoever made this table wasn't thinking prudently. Anyway, I would like to make the table look like this:
StaffID, Date, Amount
123, 1/1/08, 100
123 2/1/08, 200
123 3/1/08, 300
Where the StaffID and Date are concatenated keys.
Is there a way to either create a View or create a Query Table that converts the data like that for me? I need the new view/query to update when the original table updates, so a new table isn't an option.
Thanks ahead of time!

In SQL 2005, is it possible to read the date modified of a file which is located on the hard drive of the server? Is there a procedure/function that would allow you to do so?

I have a fact table that has terminations. Fields include EmployeeName, TermDate, TermReason, and HireDate, et al.
I need to make EmployeeName available to drillthrough, and since it's a varchar field I can't make it a measure, so it has to be a dimension attribute. My question is, should I leave the fact table as it is and use SSAS to create a dimension that contains only EmployeeName and the link to TerminationID? Or should I redesign the OLAP tables so that EmployeeName is in a separate table?
