Why can data redundancies be completely eliminated?

Data redundancies can be completely eliminated through the implementation of normalization techniques in database design, which organizes data to minimize duplication. By structuring data into related tables and establishing clear relationships, each piece of information is stored only once. Additionally, employing strict data governance and integrity constraints ensures that updates and deletions are consistently managed, further reducing redundancy. However, it's important to strike a balance, as some level of redundancy may be necessary for performance optimization and data retrieval efficiency.
