Using SQL transactions can make university database operations work a lot better in a few important ways:
Atomicity: This means that every part of an operation must finish successfully, or none of it does. For example, when a student signs up for a class, both enrolling and paying for the class happen together in one go. If something goes wrong with one of those steps, everything rolls back to how it was before. This keeps things consistent.
Consistency: Transactions make sure the data stays correct. If a new professor starts working at the university, their information, like the classes they teach and the assignments for students, needs to be updated all at once. This way, nothing gets mixed up.
Isolation: When many transactions happen at the same time, they can still work without causing problems for each other. For instance, if several students try to enroll in classes at the same time, they can do so without messing up each other's actions.
Durability: Once a transaction is completed, the changes stick around even if the system crashes. This means the information remains reliable.
In summary, these qualities help university database operations run more smoothly and create a better experience for everyone using the system.
