As suggested by this reference implementation, in some cases blending the relational and dimensional models may be the right approach to data warehouse design.
Hi.
I plan to build an application which takes text data from a user.
It then sends this to a website, login required.
The business case being this site contains many text fields, mostly redundant to user. My application would only prompt user for necessary text.
What language, methods... (4 Replies)

Whilst at DAMA last week I managed to miss the Teradata talk on “active data warehouses“. Luckily James Taylor blogged comprehensively on the talk, and although it seems Teradata declined to make the presentation available to attendees, I’m guessing it was... (0 Replies)
Hello,

Ace::Model(3pm) User Contributed Perl Documentation Ace::Model(3pm)NAME
Ace::Model - Get information about AceDB models
SYNOPSIS
use Ace;
my $db = Ace->connect(-path=>'/usr/local/acedb/elegans');
my $model = $db->model('Author');
print $model;
$name = $model->name;
@tags = $model->tags;
print "Paper is a valid tag" if $model->valid_tag('Paper');
DESCRIPTION
This class is provided for access to AceDB class models. It provides the model in human-readable form, and does some limited but useful
parsing on your behalf.
Ace::Model objects are obtained either by calling an Ace database handle's model() method to retrieve the model of a named class, or by
calling an Ace::Object's model() method to retrieve the object's particular model.
METHODS
new()
$model = Ace::Model->new($model_data);
This is a constructor intended only for use by Ace and Ace::Object classes. It constructs a new Ace::Model object from the raw string data
in models.wrm.
name()
$name = $model->name;
This returns the class name for the model.
tags()
@tags = $model->tags;
This returns a list of all the valid tags in the model.
valid_tag()
$boolean = $model->valid_tag($tag);
This returns true if the given tag is part of the model.
path()
@path = $model->path($tag)
Returns the path to the indicated tag, returning a list of intermediate tags. For example, in the C elegans ?Locus model, the path for
'Compelementation_data" will return the list ('Type','Gene').
asString()
print $model->asString;
asString() returns the human-readable representation of the model with comments stripped out. Internally this method is called to
automatically convert the model into a string when appropriate. You need only to start performing string operations on the model object in
order to convert it into a string automatically:
print "Paper is unique" if $model=~/Paper ?Paper UNIQUE/;
