Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Force.complatform server in conjunction with calls to the Force.com API.
Apex code can be initiated by Web service requests and from triggers on objects.
All Apex runs entirely on-demand on the Force.com platform, as shown in the following architecture diagram:
Apex is compiled, stored, and run entirely on the Force.com platform.

Apex provides built-in support for common Force.com platform idioms, including:
- Data manipulation language (DML) calls, such as INSERT, UPDATE, and DELETE, that include built-in DmlException handling
- Inline Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) queries that return lists of sObject records
- Looping that allows for bulk processing of multiple records at a time
- Locking syntax that prevents record update conflicts
- Custom public Force.com API calls that can be built from stored Apex methods
- Warnings and errors issued when a user tries to edit or delete a custom object or field that is referenced by Apex
