Content Management Apps.

Drupal CMS supports the creation, management, distribution, publishing, and discovery of web information. It covers the complete lifecycle of the web pages, from providing simple tools to create the content, through to publishing, and finally to archiving. The CMS also allows you to manage the structure of the site. That is, where the pages go, and how they are linked together. Many even offer simple drag-and-drop restructuring of the site, without breaking any links.
The software provides authoring (and other) tools designed to allow users with little or no knowledge of programming languages or markup languages to create and manage content with relative ease of use.
Drupal CMS administration is separated into five main sections: Content, Appearance, People, Structure, and Configuration. The administrator can easily administer basic site configuration settings, such as changing your site slogan, modifying default language and date/time settings, creating site-wide and custom RSS feeds, and much more. The administrator can tweak and fine-tune the site by setting blocks, and creating menus.

Users and Permissions
Drupal CMS comes with great options for new user accounts and user permissions. Users can be assigned one or more roles, and each role can be set up with fine-grained permissions that allow users to view and create only what the administrator permits.

Content Management
Manage your content with an easy-to-use web interface. The CMS provides custom forms that allow administrators to create and manage content without needing to know HTML or CSS.
The flexible core handles countless content types, including pages, blog posts, video, podcasts, polls, and files and images. Site administration is easy with the robust user management, menu handling, real-time statistics, and optional revision control.
The WYSIWYG module allows client-side editors to edit content and your users to easily create rich text pages or comments. The module also simplifies the installation and integration of the editor of your choice, whether you choose an HTML-editor (a.k.a. WYSIWYG), a pseudo-editor (buttons to insert markup into a text area), or even Flash-based applications.
Field- and Content Type-level access control allows site owners to delegate content creation responsibilities to other members of the site. The Diff module provides a full-featured revision control system for your content that includes revision comparison and restoration.

Dashboard
Drupal CMS comes with a new Dashboard feature, a module that provides users with personalized dashboard pages similar to iGoogle or MyYahoo. This administrative page can be customized to provide quick access to the tools you use most, links to manage your content, or simply lists of new comments or users.

Extending Administration Possibilities
The Views Bulk Operations module further extends administration possibilities. It provides a simple and easy-to-use moderation system by defaulting your content to the unpublished state and then setting it to publish at set times. It can also perform bulk operations on custom lists of content built by the Views module.

Command Line Tool for The CMS
The CMS  Shell (Drush) simplifies site administration by allowing you to use a single command to complete multi-step operations, instead of spending hours hacking away at the command prompt. A command line shell and scripting interface, Drush can automatically update your modules and core to the latest version, install and enable modules, clear your cache, and even run module functions such as cron hooks.

Organize & Find
Organizing and finding content is easy no matter how much content you have. Spend less time looking for information, and focus on getting things done.
There are several ways to find content including breadcrumbs, menus, and core search. Tight integration with the Apache Solr module gives you a faceted search engine that provides a 'no-dead-ends' approach to finding content.
When it comes to content storage, you have many options with. The framework can be used with any database server, including MySQL, Microsoft SQL, Oracle, and many others, so you are not locked into a single company.
