- Normalization Show all the steps as you perform normalization for each problem up to 3NF. State your final relation to schemas in 3NF.arrow_forwardNormalize Table 1 to a set of Third Normal Form (3NF) relations. Your answer should show all the three stages of normalization (1NF, 2NF and 3NF) by using the Database Design Language format (underline all primary keys, composite keys and use an * to indicate the foreign keys). State the action taken upon the table(s) for each Normal Form. For the INF in this case, only identify the Primary Key and keep the INF result in a single table. Then, split into new table(s) starting from a) 2NF onwards.

The offering relation is the specific instance of a course being taught in a given term, and is the entity which will be associated with the student enrollment. Students are enrolled in these offerings and achieve a mark.
