Oracle Database Discussions

Hi! I need help in fragmenting tables in my database.
I'm new to distributed database, but i want to fragment data in my database to meet this reequirement:
for example: if my database contains data of students from different campus within my institution, how will i fragment my database to display only the data about the students in a particular campus.
I'm learning about horizontal and vertical fragmentation but i just dont understand how they work..
Please can you explain how they both work using a table as an example.
