Apex

Another proprietary programming language, Apex is used by Salesforce to execute flow and transaction control statements and calls to the API in Salesforce servers. It’s an object-oriented language that’s similar to Java and C# that allows Salesforce developers to add business logic to many system-related events. Thus, software engineers that use it do so exclusively because of what Apex can give them in Salesforce.
