Adobe CQ5 Introduction

Adobe CQ5 is one of the java based web content management system. It combines with DAM, CRXDE Lite, inbox, website console, social collaboration, workflow, campaigns, Users & groups etc. It uses Sling framework, CRX content repository, felix (OSGi framework).

There are three important persons in Adobe CQ5 website creation

Developer – One who create the component

Author - One who Create, modify, delete the content using component and activate the page to publish

End User – One who visit the site

There are two instances in Adobe CQ5

1.      Author instance

2.      Publish instance

Author instance

            It provides the developer to create the new component, templates, workflow, etc. It allows the author to create, edit, delete and publish the content to publish instance

Publish instance

            End user visit the site from publish instance. Here you can’t create, edit or delete the content. Note: It runs with minimum files which is need for publish instance

Note:

Why author instance and publish instance?

         In real the world, sites contents are changed daily bases. So that, They separate the authoring and development in the author instance. Deploy site, load balancing, etc in publishing instance. They maintain the workflow while publishing pages from author to publish environment. 

Android Activity

In Android, Activity is like state  of the application. Each activity has a layout. Activity has a lifecycle.

1. onCreate()

2. onStart()

3. onRestart()

4. onResume()

5. onPause()

6. onStop()

7. onDestroy()
