Drupal development

Basics

Drupal's basic building blocks - the search for core, Ronald Ashri, Nov 2009
Drupal programming from an object-oriented perspective

Drupal as an Application Development Framework - great dev overview video, shame about the audio

Architecture

Drupal dev docs - "Newcomers to Drupal development should read the conceptual information provided in the 'Components of Drupal' section, and then proceed to examine one of the heavily-documented example modules below. The examples are fully-functioning Drupal modules, so you can download them from the contributions repository and alter them as you experiment."

Preying on the drupal_alter() - API overview video. somewhat quiet sound. [1]

Menu system (path)

How the menu system works (a Drupal how-to) - how the menu system translates paths to callback functions

Content

An entity is a kind of content stack. An entity base table is tied to fields using bundles. Entity types include node, comment, taxonomy term, user profile, organic group, etc. Entity types can allow bundling or not (creating types of node node vs. users, though see the Profile 2 module). Fields are used to store and display various data types, and can be reused across bundles and entities.

How to create a new entity

hook_entity_info - "Inform the base system and the Field API about one or more entity types."
