Relational database design is really important for reducing the repeating information, especially in university applications. By cutting down on this extra data, we can make sure the information stays accurate, save storage space, and make everything run better.
Normalization: This means organizing tables so that we don't have repeated data, and that each piece of information connects correctly. There are different levels of normalization, and the third level (called 3NF) is commonly used in university databases. Following these rules helps us store each piece of data only once.
Table Structuring: Structuring tables correctly means setting up groups like Students, Courses, and Enrollments with clear details. For example:
Keys: Primary keys are like unique codes for each record, while foreign keys connect different tables. This means we don’t have to repeat student or course information. For instance, using StudentID and CourseID in the Enrollments table helps us avoid creating extra entries for students or courses.
To sum it up, relational database design uses normalization, well-organized tables, and keys in smart ways. This thoughtful approach greatly reduces repeating information in university applications. It helps create a strong and efficient database that supports both learning and administration.
