Data modelling layers: do you wanna get logical or physical
218689
An introduction to data models Interview In the bad old days we used to progress from "current physical" to "current logical" models. We then used to transform the "current logical" to the "new logical" â and about then the deadline cut in and we scurried about hacking the code for the new system which is about as "new physical" as you can get. No wonder the agile people noticed that it made more sense to devote your time and intelligence to the "new physical", which wasn't going to be thrown away soon after you finished.â¦

Cal Evans has posted a tutorial on the Zend Developer Zone (posted today) about using the PEAR Structures_DataGrid package to create quick and easy data tables.   In this article, I'll be introducing you to the Structures_DataGrid package, showing you how it can be used to display structured data in tabular form. I'll be showing you how to hook it up to various data sources (including a CSV file, an RSS feed and an Excel spreadsheet), and how to format the resulting output so it's as pretty (or as ugly) as you want it to be.   They talk about what you'll need to get started (the different packages for different kinds of data) and some sample code to help you down the path to more attractive tables. There's even a bit touching on some of the more advanced features like exporting to Excel, pagination and data sorting.

Flexible strings Hands on, part 1 You may find this hard to believe, but there was a time before XML hell, when the idea was that XML was going to solve just about every tricky problem in software development. From swapping data between applications or platforms, to storing complex data structures in a portable format - XML was the answer.â¦

The previous article introduced the Doodle drawing application. This week, an application framework is added, complete with a document-view architecture. This powerful programming technique separates the document data from the view. By Guyon Roche. 0929

A different sort of abstraction layer project has been started up and has already seen a few releases - Forage. As mentioned on Rob Young's blog:    Recently I've been working on a search abstraction library for PHP called Forage. The idea is to bring to search what we've had for relational databases for quite a while, abstraction.    On Friday I put up a preview release with three backends; Solr, Xapian and Zend Search Lucene. At the moment it has the bare minimum of features but there will be more soon. In this post I'm going to talk a little about the motivation for the project and then walk through a short example.    He talks about the need for search abstraction (integration and resilience to change) before getting into an example of some code that grabs the data from an RSS feed, passes it in to the Xapian search engine and stores it before looking it over for thier search terms ("yahoo microsoft").   You can download the library if you'd like to try it out for yourself.

Fast company It&#146;s a familiar tension in business. Business people think designers are mere stylists; designers think business people are Neanderthals who forfeit quality for profit. That&#146;s because traditional business runs on logic that is inductive (using observation to prove something works) and deductive (using principles to prove that something must be). But designers rely on abductive reasoning. Huh? It&#146;s ...

As important as a physical supply chain Readers may recall that I wrote last year about Silver Creek SystemsÂ®. At that time I extolled its capabilities for product data quality (matching, cleansing and classification) through the use of semantically-based content profiling and attribute identification. This is particularly relevant when information comes into the organization in unstructured formats as most conventional data quality tools have historically been limited to support for structured information.â¦

Analysis paralysis: part two Teams can get stuck wallowing in trivial details when modeling in UML. Sweating such details can lead to frustration and premature, and rash, decisions on using UML later in a project. But how do you know when a particular nuance is inconsequential and when it's an important item to specify?â¦

In this section we look at validating XML documents against XML schemas. Topics covered include: retrieving XML data, accessing relational data through XMLType views, using XMLType views and performing DML operations on XML schema-based XMLType views. By Yuli Vasiliev. 1001

IT infrastructures have become sufficiently complex that it's a challenge to peel through the layers of abstraction and aggregate the various components that determine the recoverability of an application.
