Re: Looks like hard to find data modelers in the CF community

2006-04-10 Thread Deanna Schneider
And, so, what - you're looking for someone to come up with your data model
for you? Are you offering to hire someone to do it?

I think asking for an example of one isn't going to get you very far. Data
models (whether logical or physical) are based on business requirements. I'd
assume that the business requirements for this particular customer are very
precise.

You seemed to indicate before that they already have a data model in a
teradata server (I must admit I know nothing about teradata). I'd start with
their existing data model. Typically, if this is their live data, it's
probably optimized for a lot of reads and writes. In a data warehouse,
you're probably more interested in optimizing for report generation. But,
again, without knowing what kinds of reports they'd want to generate out of
their warehouse, it's not like anyone could give you much input.

 I think it's a faulty assumption that just because no one knows of an
 off-the-shelf data model for a project for which we have no parameters
 that
 there are no data modelers in the CF community. I love data modeling. In
 fact, if anything, I probably jump into data modeling too early on in a
 project, just because I'm so excited about that aspect of it.

 I went back and reread the original thread, and I guess I'm still not even
 sure what you're asking for. There are examples of data models out there
 for
 various projects. I happen to have 2 sitting on my desk right now for
 shopping cart products. What are you trying to resolve with this data
 model?

Re: Looks like hard to find data modelers in the CF community

2006-04-07 Thread Rick Root
I would agree that it's web development as a whole, not just CF.  I'd 
wager that the only area you don't see this problem (as much) would be 
java developers.  The average java programmer comes from a programming 
background I think.

So many web developers are not CS majors by default, they maybe started 
out as graphic designers who learned dynamic web page development using 
ASP, php, CFML, etc.  Relational database design isn't always the 
easiest concept for some people to grasp.

I wasn't a cs major either, though I'd be programming all my life as a 
hobby (I wrote a terminal emulator for my Commodore 64 once!), I was 
never a disciplined programmer.  Never really dealt with databases as 
well until 1996 when I was asked to build a cost estimating application 
using VB and Excel.  We were a small company and our resident database 
specialist who was responsible for maintaining our SQL Server 6.5 
installation taught my the basics of relational database design and 
normalization and such.  She was actually very good.

10 years later, I still learn things about how best to design databases 
and run queries, because I work with extremely large amounts of data 
here at Duke... millions of rows.   Bad database design doesn't always 
become noticable to people until you've got a lot of data and your 
queries start to suck.

I wrote one app just recently than ran a lot of queries.  It ran fine 
with test data until I realized that the spreadsheet I was generating 
had 1800 rows and I was running 22 queries for each row.  That's 39,600 
queries.  I ended up creating a view and doing some other stuff to drop 
the number of queries to 3600 and it runs fine now - 5-10 seconds. 
Which is fine for a report that only runs once a month :)

2006-04-07 Thread Nick de Voil
 Looks like it is hard to find data modelers in the CF community.

Well, one here, but...

First, what exactly are the characteristics that you want to test?
Functionality, usability, performance...? For the purposes of this test, why
does it matter if it's the type of data model you describe, or even a good
data model? Or is it more of a demonstration that you want to set up?  Isn't
populating the data going to be a bigger problem than designing the data
model?

Second, I would say the best data model is the one that best matches the
enterprise rules encapsulating a particular set of requirements. So no-one
can say which off-the-shelf one is best for you without knowing your
enterprise rules. I've never used an off-the-shelf data model and I can't
imagine how you'd evaluate one properly - you'd have to study it to see if
it matched your requirements, but presumably the vendor wouldn't let you do
that.

The database is like the foundation of your house.  If you don't get it right

CF interacting with Teradata Server:

 There is an application that is built entirely in Coldfusion for doing ETL
(Extraction Transformation and Loading) of data from one database into
another.

 Now, in order to test this tool on a real time project, there is an
unrelated issue that is taking time. We need to design the database in
Teradata and then use this tool to map data from SQL Server tables into
Teradata tables.

 In order to create the database design, I have been asked to find out the
best Logical Data Models there are in the industry. The company is willing
to pay money to purchase those models. We are looking for retail LDM samples
in general and coupon business related in particular.

 I do  not know how to do the research and find the best commercial LDM out

Re: Looks like hard to find data modelers in the CF community

2006-04-07 Thread Discover Antartica
I am trying to create a Logical Data Model for Coupon business over the 
internet. The client is a sort of amazon.com for coupons. We need to build a 
data warehouse for them.

I think it's a faulty assumption that just because no one knows of an
off-the-shelf data model for a project for which we have no parameters that
there are no data modelers in the CF community. I love data modeling. In
fact, if anything, I probably jump into data modeling too early on in a
project, just because I'm so excited about that aspect of it.

I went back and reread the original thread, and I guess I'm still not even
sure what you're asking for. There are examples of data models out there for
various projects. I happen to have 2 sitting on my desk right now for
shopping cart products. What are you trying to resolve with this data model?

 know of any mailing list for database designers or data modelers?

 The CF application that we have created for ETL is going to be shot dead
 before it is even sold to the first client if the Logical Data Model issue
 is not resolved. There are already talks about trashing the entire tool.

 I know this is unrelated, so again, I apologize.

 It is a, if you will, a baby copy of Informatica (informatica is the 800
 pound guirella in the ETL market).

  There is an application that is built entirely in Coldfusion
  for doing ETL (Extraction Transformation and Loading) of data
  from one database into another.

 I'm off topic from your original post, but what is this CF based ETL?  I
 had no idea such an animal existed...or is that what you are trying to
 build?
