Simplifying the way to understand Dynamic Apex in Salesforce: Part - 1

From the very beginning, Dynamic Apex had been difficult for me to understand. This time I thought of going slowly through it and thereby finding a simple way to understand its basic implementation first.

Since I do this now, it's worth sharing here. 

Dynamic Apex implementation in Salesforce focuses on four major areas:

• Apex Describe Information
• Dynamic SOQL
• Dynamic SOSL
• Dynamic DML
