Triggers

I often receive emails from learners about the challenges they face during interviews. In interviews, we are typically given real-world scenarios and asked to suggest solutions. When we only have basic knowledge from reading interview questions, we can struggle to provide solutions to the questions asked. What I believe is that it's more important to focus on understanding basic concepts rather than just memorizing interview questions. This approach will not only help us master the fundamentals but also enable us to come up with solutions for questions we may not have encountered in real-life situations.

In this course, I will cover APEX TRIGGERS IN SALESFORCE.

We will learn what triggers are in Salesforce, how to use them in real-time development, and explore various scenarios. I aim to cover everything you need to know about triggers, from the basics to advanced topics.
