Called the sandbox finally the tested changes can be

called the sandbox . Finally, the tested changes can be deployed to a live production
environment edition. The production environment is the live environment that is
used by the users and contains live data. The production instance does not allow
developers to code in them directly; this ensures that only debugged and tested code
reaches the live organization.
Online page editor and the Eclipse
Force.com IDE
Force.com provides a built-in online editor that helps edit Visualforce pages in
real time. The online editor can be enabled by checking the Development Mode
checkbox on the user pro fi le, as shown in the following screenshot:

The online page editor splits the screen into two parts with live code in the bottom
half and the fi nal page output in the top half. Force.com also provides an inline
editor for editing the Apex code in the browser itself.
Force.com IDE is an IDE built over Eclipse. It provides an easy environment to write
code and of fl ine saving. It also comes with a schema browser and a query generator,
which helps in generating simple queries (
select
statements) by selecting fi elds and
objects. The code is auto-synced with the organization.
Sandboxes
Force.com provides a real-time environment to develop, test, and train people in the
organization. It is a safe and isolated environment where any changes made will not
affect the production data or application. These sandboxes are used to experiment on
new features without disturbing live production in the organization. Separating the
test and
dev
instances also ensures that only the tested and veri fi ed code reaches the
production organization.

There are four types of sandbox:
• Developer sandbox : This environment is specially used to code and test the
environment by a single developer. As with the configuration-only sandbox,
this also copies the entire customization of the production organization,
excluding the data. An added feature of a developer sandbox is that it allows
Apex and Visualforce coding.
• Developer pro sandbox : Developer pro sandboxes are similar to developer
sandboxes but with larger storage. This sandbox is mostly used to handle
more developer and quality-assurance tasks. With a larger sandbox, we can
store more data and run more efficient tasks.
• Partial copy sandbox : This is used as a testing environment. This
environment copies the full metadata of the production environment and a
subset of production data that can be set using a template.
• Full copy sandbox : This copies the entire production organization and all its
data records, documents, and attachments. This is usually used to develop
and test a new application until it is ready to be shared with users. Full copy
sandbox has the same IDs of the records as that of production only when it
has been freshly created.
