How can I create an account edit page using Lightning Component in Salesforce?

Hi Laveena,

The simplest way to create a form that enables you to edit a record is to use the lightning:recordForm component. If you want to customize the form layout or preload custom values, use lightning:recordEditForm. If you want to customize a form more than the form-based components allow, use force:recordData.
