Description

Introduction

Salesforce Apex is a strongly typed, object-oriented programming language. It allows developers to execute flow and transaction control statements on the Salesforce platform. Additionally, it is used to build custom business logic, automate processes, and integrate with external systems. By mastering Apex, developers can create complex applications and customize Salesforce beyond its standard functionality.

Learner Prerequisites

• Basic knowledge of Salesforce CRM and its data model.
• Understanding of object-oriented programming concepts.
• Familiarity with Salesforce declarative tools, such as Process Builder and Flow.
