Implementing A Simple Data Dictionary Via Extented Properties
Jun 25, 2007
Hi,
I'm thinking of implementing a rudimentary Data Dictionary for a database using extended properties to store table and column descriptions.
Does having this information for every table and column in a database (200 tables; 2000 columns) cause any (negative) impact on database performance? I'm guessing it shouldn't but want to make sure before implementing this in the production environment.
Thanks,
Smitha

In SQL 2k5 every db object say table , table fields etc have extension properties . I plan to populate these extension properties with meta data related information like field description , string length , case conversion , field alignment , enum options etc .
I wish to know if anybody has done, anything like this . Can this properties be easily avaialble in .Net development , reporting services , BIDS etc . Can there be significant advantages wrt this .
I would like to get user experiences .

I'm not trying to do anything too fancy; given a string, I just wanna see if anything in the column of my database matches the string. I'm using an SQL query that takes a string, then selects the data using LIKE %searchword%.This works fine when the user enters only one word. But I guess you can see that a problem arises when they enter more than one word.So how can I implement a very simple search that will take more than one word?

Is there any tool for data dictionary? Basically there are no
descriptions/comments to many of the columns (about 99%) in the database. Datawarehouse team does not know exactly what those columns are, where its used, how its used. No comments have been defined in the system tables. We would like to have a tool where SME's/Bussiness analysts enter the description for the columns in the production database. We have SQL Server databases, many oracle dbs, few sybase databases, ACCESS. Sometimes we might have to search for strings in the descriptions entered.

I need to build a data dictionary for a SQL 7 DB that already exists that has over 16000 columns. What I really need is to add a comment to the table and column names.We use ERWin and have looked at the Microsoft Repository
but I would like a quick interface to create the descriptions which neither one of these have. I scripted out all the table and column objects into tables and built a simple Access Form to handle the updates. Now I need to
commite these updates to the Microsoft Repository. Has anyone seen or tried something like this?
THanks

I am adding tables to a DB. I want to put table and column descriptions in as I go.
1. Is there a "Description" property for the table? I see in the column properties list a "description".
2. Once I have my descriptions all in, indexes set etc, is there a system stored procedure that I can run that will generate the data dictionay? (With a table description.)
Thanks

Hi ,all here,
Would please anyone here give me any guidance and advices for best practice of data dictionary in SQL Server 2005?
I have restored a large insurance claims database with up to more than 300 tables, massively, most of them are empty tables, many of them dont have any keys, contrains, indexes, and more difficult, there is no any data dictionary for the database which gets me stuck in the understanding of the data at the moment. Thus I think data dictionary is very important for a database.
Will anyone gives me advices for that? Really need help.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

Hi,
in my application, the data is in hierarchical format. there is a tree with set of nodes having parent child relationships. this data can be stored either through adjacency or nested set model approach. this is fine. but the issue here is that each child node inherits the properties of its parent node, parent's parent node and so on until the root node. lets say root node has two attributes A1 and A2 and they are stored in two columns in a table. but its child nodes inherits this data from its parent and it has its own extra attributes. so should I copy parent's data for the child node as two additional columns? the problem is that there are around 15 levels in the tree and the attribute list grows from top to bottom in the tree. lets say I need to find all the attributes for a leaf node in the tree (both direct and inherited), if I am not storing the inherited attributes for each node, then I need to walk-up the tree and find all the inherited attributes. there are around 30K nodes and each node has around ten attributes. xml is not option because of large volumes of data and auditing and reporting on individual nodes. what is the best way to store this type of data? my current approach is to have an attribute table having nodeid as a foreign key and only store the direct and NOT the inherited attributes of the node in the table, but this means to find all the attributes for the node, I need to gather the attributes of all the parents until the root node. I can't see any easy way out for this.

Has anyone implemented split data for an application between two databases because the data size is extremely large? If so could you please point me to relevant information.In this split data scenario, a table will automatically carry over to another database whenever the size limit for the current database is reached. The challenge is here for the DAL (data access layer) to automatically look into the appropriate database when the next row of data is in another database. OR Perhaps there is another solution to this terasize data problem..Any help on this would be greatly appreciated.

I found it pretty interesting. I checked the size of a database, before implementing database compression across all the user tables in a database. And Post implementation of compression too I checked the size of the database.
I did not find any difference. But if I expand the table and check propetires->storage and I can see that PAGE compression is implemented across all the tables, but no compaction in the size of the db. It still remains the same.

Implementing data mining Add-in in an academic setting? We need to handle over 150 new students a semester and have their connection to Analysis Services survive for their four years at the college. We are introducing data mining to every freshman business student as a unit within their Intro to Excel class (close to a month of work to give them a sense of what is possible). Other courses later in their curriculum will expand on that introduction.
Once implemented, we would have as many as 900 connections to manage (four years from now). It is possible that multiple sections will be running at the same time, so 40 students may be accessing the data mining tools concurrently.
Is there a way to "bulk establish" the access credentials and establish those databases?

I have an ODBC connection string that is working fine with the following properties:
Database="XXXXXXX",Network="YYYYYY"; strangely no server is specified in the string, but it is specified in the ODBC Connection file.
I am trying to do a new server registration in SSMS for this database.However, I don't understand where the network spec is placed.
Under Registered server name I've tried:
YYYYYYXXXXX
When I browse the server for the database instance list, I receive "network path was not found".
I even tried:"XXXXXXX",Network="YYYYYY" for the registered server name.Same error message.
What am I doing wrong ?

Hi,
I have SQL Server 2005/BIDS installed on a 64-bit server. When I open an SSIS package the properties window for each of the Data Flow tasks is empty. The properties window is there and displays correctly for other types of task but for the Data Flows it only shows the name of the task. To further compound my misery if I try to open a package that dynamically sets a property of a Data Flow task (using an expression) the package fails to open with errors concerning reading the XML of the package.
Packages containing Data Flow tasks still run on this server (both in BIDS and using dtexec) as long as they don't contain expressions that set any Data Flow properties.
Any ideas?
Thanks

I'm developing a report which contains a number of matrixes which are ordered in a hierarchy which can be navigated using a document map. One of the matrixes contains a subreport containing a table which displays a description for the matrix and the corresponding document map label. This is working without problem already in the production environment.
Recently, after updating my machine with numerous updates and patches, this stopped functioning. I now receive the error message, "The given key was not present in the dictionary" when I run this subreport, either as part of the greater report or on its own.
I have seen the posting which recommends deleting the report.rdl.data files. This did not solve the issue.
The data and the dataset are both in sync. When I click the "Print layout" button when previewing the report in Visual Studio .Net 2005, I can view the data. This looks like a bug in the VS.NET 2005 report designer.
I am running SQL Server 2005 SP2.
Any help is appreciated.
Regards,
Bill Mueller

I am trying to read in a flat file, transform the fields and store into a destination database.
In DTS, this works using Transform Data Task Properties. I define the columns and then have a VB script on the Transformations tab that changes any bad data.
Is there a way to do this in SSIS that I can define the column transformations and re-use my VB scripts?

I need to sort my data more than just order it using Order by clause.
I need the, to appear so that they are sorted like in dictionary's order.
example: if I have 0.1 and 0.2 and 0.11
They need to be ordered into 0.1 then 0.11. then 2.0. etc.
I thought I could use Val() function but it wasn't a successful attempt. Anyone can help me please?
I'm using ColdFusion and this is one of the query :
<cfparam name="sort" default="goal_cd">
<cfquery name="GetTheme" datasource="#application.OUSDSN#">
Select goal.*,theme.*
From goal,Theme
Where goal_theme_id = theme_id
Order by #sort#
<cfif sort is "goal_cd">
Order by Val(#sort#) <--------------------- This doesn't work!!!
<cfelse>
Order by #sort#
</cfif>
</cfquery>

Hey all-
I put togehter a package that opens a flat file, parses the data based on the semi-colon delimeter, and imports the rows into a database table. Thats the fun easy part.
What I cant figure out is how to add a variable that will hold a constant ID value that will be persisted with the same value to all rows inserted to the DB. Making the problem harder, I would like that this value be defined in a properties file or database table of some sort so that I can do a lookup based on the file name / location to find out what value should be used.
Any suggestions? I hope my explanation makes at least some sense - but basically I want to do a look up in a configuration of some sort, pull out a single value, and add it to a data import.
let the fun begin!!

I have connected to the SQL Server 2005 instance usign the SQL Server Management Studio; I have changed the default locations for the database and log files. I have also rebooted the machine. When I look in the SQL Server Configuration Manager in the properties for the SQL Server (MSSQLSERVER) I see that the data path is still set to the old value and this field is read-only. How can this can changed without going through the registry?

I implemented a custom source adaptor. I want to be able to associate custom properties with each of the output columns. I want them to be passed downsteam. The idea is to be able to retrieve these information in a downstream custom transformations of ours and process the various columns accordingly. How do I go about doing this?I noticed that the IDTSCustomProperty90 seems to have a local scope only.
