Drupal is built…

Standing on the shoulders of…

Each other

Drupal Principles

Modular and extensible. Drupal aims to provide a slim, powerful core that can be readily extended through custom modules .

Quality coding. High quality, elegant, documented code is a priority over roughed-in functionality.

Standards-based. Drupal supports established and emerging standards. Specific target standards include XHTML and CSS.

Low resource demands. To ensure excellent performance, Drupal puts a premium on low-profile coding (for example, minimizing database queries). Drupal should also have minimal, widely-available server-side software requirements. Specifically, Drupal should be fully operational on a platform with a web server, PHP, and either MySQL or Postgresql.

Open source. Drupal is based on the open source philosophy of collaborative free software development and is licensed under the GPL. Drupal is itself open source and builds on and supports other open source projects. Specifically, Drupal is coded in the open source scripting language PHP and supports as primary data sources the open source database formats MySQL and Postgresql.

Ease of use. Drupal aims for a high standard of usability for developers, administrators, and users.

Collaboration. Drupal development supports open, collaborative information sharing systems and approaches.

Curation Tool

Node import

CCK

Exhibit (using Josh Huckabee's tutorial).

Allows us to import a spreadsheet of a lot of data and have very quick and powerful data filtering/visualization set up very quickly with the ability to curate the data at will which we did not have using Exhibit alone. Of course, once it's set up, adding data manually is pretty easy and we also have the ability to programmatically add new data records.

Drupal 7

Currently in code freeze:

Bug patches only

With a few exceptions

Release when it’s ready

Expanded automated test coverage should shorten cycle

#D7CX pledge http://bit.ly/121D6T - components ready on the day Drupal 7 is released

Drupal 7 changes - General

Install consolidation

Fewer pages with more logical arrangement

Users can cancel accounts!

Improved translation interface

Improved and expanded help integration

Administration theme

More error reporting options

Drupal 7 changes - Theming

Page template XHTML refactored

More semantic class and ID names

Friendlier to CSS only layout

CSS only means no template changes needed (i.e. no PHP)

Better JavaScript cross library integration

JQuery 3.x

Library calls are wrapped

(function($) { $('a').fadeOut().fadeIn(); })(jQuery);

Drupal 7 changes – automated testing

SimpleTest integration

http://testing.drupal.org

Drupal 7 changes - DBTNG

Using PHP data objects (PDO)

Direct support of MySQL PostgreSQL & SQLite

Implied support for others

Transaction support

Replication support (master/slave)

Potential for update automation

Dynamic select queries

Geek alert:

Hook_query_alter replaces hook_db_rewrite_sql

New static select query syntax

Drupal 6:

Drupal 7:

$node = db_query('SELECT nid, title FROM {node} WHERE type = :type AND nid = :nid', array(':type' => $type, ':nid' => $nid))->fetchObject(); $result = db_query("SELECT nid, title FROM {node} WHERE type = '%s' AND nid = %d", array($type, $nid)); $node = db_fetch_object($result);

New dynamic select query:

Drupal 6:

Drupal 7:

$select = db_select('node', 'n')

->fields('n', array('nid'))

->condition('promote', 1)

->condition('status', 1)

->orderBy('sticky', 'DESC')

->orderBy('created', 'DESC')

->extend('PagerDefault')

->limit(variable_get('default_nodes_main', 10))

->addTag('node_access');

$result = pager_query(db_rewrite_sql('SELECT n.nid FROM {node} n WHERE n.promote = 1 AND n.status = 1 ORDER BY n.sticky DESC, n.created DESC'), variable_get('default_nodes_main', 10));
