Apex

This category is used for posts that contains apex code or apex tricks.

Apex is a strongly typed, object-oriented JAVA based programming language used for building software as a service (SaaS) applications on top of Salesforce.com’s customer relationship management (CRM).  Salesforce is the leading CRM now. Apex allows developers to access Salesforce.com’s back-end database. It also includes an application program interface (API) that developers can use to access user data on Salesforce.com. This API allows developers to use common SaaS components without the need to develop much of the infrastructure.

Apex is interpreted, executed, and controlled entirely by the Lightning Platform. It uses Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) queries that return lists of sObject records. sObject can be seen as a SQL table. Apex also provides built-in support for Data manipulation language (DML) calls, such as INSERT, UPDATE, and DELETE, that include built-in DmlExceptionhandling.

You can save your Apex code against different versions of the API. This enables you to maintain behavior.
