Salesforce Apex

Salesforce Apex is an object-oriented programming language specifically designed for the Salesforce platform. It is similar to Java and is primarily used to implement custom business logic, automation, and integrations within Salesforce.

Key Features of Apex:

  • Cloud-based: Runs exclusively on Salesforce servers.

  • Java-like Syntax: If you know Java, you can learn Apex quickly.

  • Tightly Integrated with Salesforce Database (SOQL & SOSL): Enables direct data queries and manipulations.

  • Event-driven: Often executed through Salesforce triggers (e.g., record changes).

  • Governor Limits: Salesforce imposes limits (e.g., maximum SOQL queries per transaction) to maintain platform performance.

Uses of Apex:

  • Triggers: Automate actions when records change.

  • Batch Processing: Handle large data sets in background jobs.

  • Web Services & API Integrations: Communicate with external systems.

  • Custom Controllers for Visualforce & Lightning: Control user interfaces.
