I first got this map from SQL Server Magazine subscription. Now isee it's available to download as a PDF from Microsoft.http://www.microsoft.com/downloads/...&displaylang=enI've just installed Visual Studio Team Edition for Database Professionalsand for the next coming weeks i'll get a chance to see what kind of datamodel design capabilities the product offers.My question would be do you know how I can make our databasemodel look cool like this map? Would you know if this is a third partysoftware that does this with nice colors and all?Do you think I can do similar quality data model map using VSTE forDB Pro?Thank you

I have created a database with several tables. I want to create a database diagram to show the relationshipbetween the tables. Below are the steps from the SQL Server 2005 documentation on how to create a database diagram. The problem is that when I right click on the Database Diagrams folder I am only given two options. They are:"Working with SQL Server diagrams" and "Refresh"There is no menu choice to create a new database diagram. Can anyone tell me what the problem here is?
To create a new database diagramIn Object Explorer, right-click the Database Diagrams folder or any diagram in that folder.
Choose New Database Diagram on the shortcut menu.
The Add Table dialog box appears.
Select the required tables in the Tables list and click Add.
The tables are displayed graphically in the new database diagram.

I have a case study requesting to create an ER diagram, with the attributes listed in each entity. The data I have is an Excel Spreadsheet listing:
CustomerName
PurchaseDate
Destination
Airline
Flight#
departDate
DapartTime
ArriveTime
Hotel
CheckIn
CheckOut
Car Rental
Pickup
Return
The case is related to travel agency that specializes in booking interesting vacations for people who are single. Note that the travellers have a variety of travel bookings: some may rent a car and drive to the hotel at their destination, others may be staying with friends or relatives at their destination, while others will need flights, hotel and car rentals in their booking.
creation of the Tables and their attributes to Normalize the model to 3NF.

I have an opportunity to rebuild a database model with the express purpose of improving query performance. So given the following I have a few questions.
Table A (~500M records)
Primary Key Field (int)
Field 1 (varchar)
Field 2 (varchar)
Field 3 (varchar)
Field 4 (varchar)
Field 5 (varchar)
Table B (1B+ records)
Primary Key Field (int)
Foreign Key Field (int)
Field 1 (varchar)
Field 2 (varchar)
Field 3 (varchar)
Field 4 (varchar)
Field 5 (varchar)
* Assumed: Tables are inner joined on all queries. The database is readonly.
-- Most of my lookups are based on querying Field 1 of Table A. The data content of Field 1, Table A is 90% unique.
1) Would it be more beneficial to put the clustered index on Field 1 instead of the PK field in Table A?
2) Can an Identity column be non-clustered?
3) Alternatively, would it be beneficial to build a separate lookup table with just the PK & Field 1 of Table A, with a clustered index on the lookup table Field 1 which I join on Table A? (did that make sense?)
-- I have a secondary lookup that performs queries on Fields 1, 2, 3, 4 & 5 of Table B
1) Would it be more beneficial to create an additional indexed lookup column of the concantenated values of Fields 1-5 of Table B versus a covering index of all 5 columns?
2) Does a clustered index have to be unique?
3) Would a clustered index be more beneficial over Fields 1-5 or the special lookup column versus the PK or FK fields?
4) Would creating a special lookup table with just the requisite fields be more beneficial?
An extra question. The existing data model uses the CHAR datatype for all columns less than 9 characters wide and the columns are set to allow nulls. This requires every select statement to COALESCE() and RTRIM() all these columns. I intend to make all (affected) columns VARCHAR, NOT NULL with a default value of a 0-length string.
Will this enhance query performance?
Thanks in advance for any insight.

Hi,Facts:I created a database to support an application that tracks events ondifferent objects. The two main tables are tbl_Object andtbl_EventLog. Each table has unique ID and on the tbl_EventLog thereis FK for a record in the tbl_Object. The events are inserted all thetime for the same or different objects from the tbl_Object. There areabout 600,000 objects in the tbl_Object and 1,500,000 (and growing)events in tbl_EventLog.Question:The user often wants to know what the last event was for a specificobject.What is the best way of retrieving the last event?Should I simply do a max(eventdatetime) on a specific object? orShould I add a LastEventID column to tbl_Object and update it everytime a new event is inserted? or any other way to implement it?I chose the second method because I didn't think it made sense searchthe event table everytime the user wants to know the last event, but Iwanted to know what the experts thought.Please let me know what you think.Thank you,Oran Levin

I use data model as the datasource of my report. I want to create a new field basing on a date type field.
So I create a new field with function like this 'DATEADD(MONTH, 3, #8/18/2009#)', but there is always a error message box said 'the arguments to the following function are not validATEADD'
How should I write this function?

Hi all,
I´m a real SQL rookie and after two days of intensive research and reading of dozens of articles and web pages a bit confused about all that knowledge concerning database technology ... and I only want to do something very easy ...
Now, my question is, how can I produce a diagram from that data, that is stored in a table, maybe called "DiagData1"?
I have installed SQL Server Express 2005 and Visual Basic Express 2005 and did some first steps with it as where shown in an brilliant tutorial that I´ve found on a Microsoft (?) webpage. It shows the complete way building a database and connecting it to a form which was build with Visual Basic. So all what is left is find out how the database tables are connected to a diagram.
thanks´n greets,
VBFan

I created a data model for report builder. And since it wont let me use views, i tried to put all the tables im using in one of my already made views, to create a data source view like my sql view. But when i connect everything the same, my report model still doesnt narrow my search. I only want to see Breed information, but since i have a Breeder table,and Customer table, its showing me all customers, and not limiting it to the ones that are breeder customers.
heres the tables:
Code Snippet
FROM dbo.Tbl_Customer INNER JOIN
dbo.Tbl_Customer_Breeder ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Breeder.Customer_Code INNER JOIN
dbo.Tbl_Customer_Detail ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Detail.Customer_Code INNER JOIN
dbo.Tbl_Customer_Category ON dbo.Tbl_Customer.Customer_Category_Id = dbo.Tbl_Customer_Category.Customer_Category_Id INNER JOIN
dbo.Tbl_Customer_Classification ON
dbo.Tbl_Customer.Customer_Classification_Id = dbo.Tbl_Customer_Classification.Customer_Classification_Id INNER JOIN
dbo.Tbl_Customer_In_Breed ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_In_Breed.Customer_Code INNER JOIN
dbo.Tbl_Breed ON dbo.Tbl_Customer_In_Breed.Breed_Id = dbo.Tbl_Breed.Breed_Id
What am i doing wrong, and are there any suggestions.

Hello all,
Please help....
I have a text file which needs to be created into a table (let's call it DataFile table). For now I'm just doing the manual DTS to import the txt into SQL server to create the table, which works. But here's my problem....
I need to extract data from DataFile table, here's my query:
select * from dbo.DataFile
where DF_SC_Case_Nbr not like '0000%';
Then I need to create a new table for the extracted data, let's call it ExtractedDataFile. But I don't know how to create a new table and insert the data I selected above into the new one.
Also, can the extraction and the creation of new table be done in just one stored procedure? or is there any other way of doing all this (including the importation of the text file)?
Any help would be highly appreciated.
Thanks in advance.

 I want to change the work table name to work_version2 and later drop the work table. First, I created the table (work_version2) along with the data structure seen below and later inserted data from the work table. As I tried to make workID a surrogate key in work_version2 using SSMS, I got the below error message when I try to save the changes. Is there a way to do this?
Saving changes is not permitted. The changes you have make requires the following tables to be dropped and re-created. You have either make changes to a table that cant't be recreated or enabled the option that prevent saving changes that requires the table to be recreated. Work_version2.
CREATE
TABLE WORK(
WorkID  Int  NOT
NULL IDENTITY (500,1),
Title  Char(35)  NOT
NULL,
Copy   Char(12)  NOT

I am attempting to create the "Classification - Children at Home" Data Mining Model as described in Larson's book.
Each time that I create it.. ONLY the ALL LEVEL is shown and it is impossible to expand the model to look at the Decision Tree, Neural Network, or the Clustering model etc. Drill down is enabled (tried it with and without enabling the drill down).
The Children at Home field has been populated with values from 0 - 4.
Any ideas would be greatly appreciated.
regards Steve

When trying to create a DB diagram on my local SQL Server 2005 db, I get the following error:
cannot insert the value null into column "diagram_id"
I have searched the web and can't seem to find anything on this.
I just simply drag one table from my local db onto the diagram windows and try to Save it and that's what I get. I'm able to save diagrams on a networked SQL Server.
Does anybody know how I can resolve this issue?

Hi,
I€™m trying to create a DB for my course at Uni and as far as I€™m aware to create a DB on my desktop at home I need to use CE.
So I created a new DB in CE and then created some tables and I now want to create a relationship diagram but there isn€™t an option to do it. In the toolbar the relationship icon is permanently greyed out and unusable and there isn€™t a node in object explorer.
Can this be done and am I just missing something obvious? I€™m running it on Vista and I have installed the latest SP, could that cause any problems?
Im going crazy and any help would be greatly appreciated!
Thanks,
Ricky

i get the following message
Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.
I am the db owner but still wouldnt let me install and create diagrams.
help!

Hi,
I am trying to model data in analysis services with the Advance Create Mining Model function in the excel addin. I am having trouble creating an association model that works like the Associate button above the Advanced button.
The format of my data is like this
OrderID Product
100 Bike
100 Helmet
100 Shoes
200 Helmet
200 basketball
200 Bat
300 Shoes
300 Socks
The associate button works perfectly since it asks me which column is the transaction id (orderid) and which column I am trying to predict (product). The advanced create mining model asks me to determine what the columns are...
OrderID=key Product=Input+Predict?
When I run the advance create mining model associate, I get a browser that gives me no rules and the support for only one item itemset (each product but no combination of products).
Does anyone know what I have to do to get it to work like the associate button?

I've been tasked to create a database diagram, save it and send that db diagram to the user. Now, I am confused as I don't know where sql server stores the db diagram...what is the path where it stores the diagram. How do I export it in case if I need to provide it to the user. How, am I supposed to grant user permission so he himself can create a database diagram.

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?Â
I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)

I am using sql2012 se and we want to use couchbase to store some data as documents. So the database will be Hybrid(partly SQLServer and Partly couchbase). However the database is still in the design phase. What are the things that we should keep in mind when designing this database from a design perspective? Our database which was completely SQLServer based(RDBMS) was using GUIDs everywhere based off NEWID() and prime goal is to get rid of GUIDs for the most part.

Hi there
We are thinking to create a small scale of the "Software On-Demand" model for Support Ticket Management System which means that the client can login to do a support tick and shared the application using the same URL.
Couple options though:
1) We design by table such has a SUPPORTS table with has a foreign key of the ClientID from CLIENTS table. This will cover that client can only can a specific data within the SUPPORTS table.
2) Alternatively, create a dynamic table which is created specifically for "Client B" for instance for SUPPORT table and it will be called such as ClientBSupport table. Something that can be common it will be shared such as like look-up table.
Couple consideration though:
1) Considered client wanting to backup this table. Obviosly it has too querying based on the client id to get the right data.
2) Security withing that table. Is the data needs to be incrypted ... I guess this is expensive excercise.
3) Possibly have a model that access to this table in querying directly etc etc.
4) If the Support table is getting larger and larger and it's not fair for small client accessing the small information which has equal to the one that has big records? Cause it's sharing table.
Any inputs I am really appreciated.
Thanks

Hi, all here,
Thank you very much for your kind attention.
I dont think we should sample any nested tables for data mining model training? Since I think any nested tables are bound to the case table. Therefore whenever we sample the case table, the nested tables are like any other input attributes within the case table to be rectrieved as inputs accordingly?
Thank you very much for any guidance to clear my confusion.
With best regards,
Yours sincerely,

I desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...
I have practiced with an example table that is not really a junction table. It is just a table I decided to use for practice. When I execute the script, it seems to do everything I expect. For instance, there are not any constraints but there are indexes. The PK is the correct column.
CREATE TABLE [dbo].[tblNotificationMgr](
[NotificationMgrKey] [int] IDENTITY(1,1) NOT NULL,
[ContactKey] [int] NOT NULL,
[EventTypeEnum] [tinyint] NOT NULL,

Hi,
I am new to SQL 2005. I have to design schema for scientific data warehouse. Data is available in 2 or more flat data files recorded at 1 sec interval. At Least 2 of the data files have 100+ columns. I am inclined to create a table per data file type. I want to know If this is correct/optimal for me to do?
I don't think I can create normalize tables based on the headers in these Data files.
Primary Objective of this data warehouse is make it available for reporting services and Analysis Services.
Any suggestions or tutorials for me?
Thanks,
Vinod Kushwaha
