Feature in Developer org

Hi,

Development environments are used strictly for developing and testing apps. These environments contain test data that are not business critical. Development can be done inside your browser or with the Force.com IDE, which is based on Eclipse. There are two types of development environments: Developer Edition and Sandbox.

A Developer Edition environment is a free, fully-featured copy of the Enterprise Edition environment, with less storage and users. DE is a logically separate environment, ideal as your initial development environment. You can sign-up for as many DE organizations as you need. This allows you to build an application designed for any of the Salesforce production environments.

Developer Edition :

1. It has 2 full CRM licenses.
2. It has 5 MB of storage.
3. It has API enabled.
4. It's Sign-up is Free!

Partner Developer Edition :

1. 20 full CRM licenses.
2. 20 Force.com Platform licenses.
3. 250 MB of storage.
4. It has API enabled.
5. This is a DE org with more storage, features and licenses. Free for enrolled partners.

Thanks
