How to create sequence item?

Hi,
i am coding VIP for one of my DUT, where i have defined interface signals by simply taking out i/o’s from DUT. I am little confused to define the sequence_item like whether i need to include all i/o’s to the sequence_item? if so what is the difference between sequence_item and interface? i need clear picture of how to code sequence item. Can anybody elaborate on this with some example codes?

You should start with the Verification Academy introductory courses.
