Apex
Apex is a strongly typed, object-oriented programming language developed by Salesforce for building business logic and custom functionality on the Salesforce platform. It runs on the Lightning Platform (formerly Force.com) and is used to execute flow and transaction control statements on the server side, integrating with the Salesforce database and APIs. Developers write Apex classes and triggers to automate processes, validate data, and create complex business applications within the Salesforce ecosystem.
Developers should learn Apex when building custom applications, automating workflows, or extending Salesforce CRM capabilities beyond standard configuration, such as creating custom business logic for data validation, complex calculations, or integrations with external systems. It is essential for Salesforce developers working on enterprise solutions, as it allows for server-side processing and direct database manipulation within Salesforce's multi-tenant architecture, ensuring security and scalability.
