In Salesforce, How will you differentiate DML and SOQL?

Hello Mohit,

SOQL(Salesforce Object Query Language) is the query language that allows you to retrieve data from the database.

for example-

Account a = [Select Name from Account where Name = 'My Account'];

DML allows you to manipulate that data via inserts, updates etc.

for example-

Account a = new Account(Name = 'New Account');

insert a; // This will insert a account

a.Name = 'Updated Name';

update a;//Update the account record

Delete a;

//delete theaccount  record

They relate to Apex in that they form part of the language. SOQL queries can be executed from Apex to retrieve information for further processing, DML allows Apex code to change the data.
