2. Normalization —Normalization is a process of refining the design of a database by removing data redundancy. The process involves breaking up a data structure into smaller and simpler parts.
3. Denormalization —This is the process of combining multiple related tables into one table. The advantage of denormalization is that it can improve performance and make reports and queries easier to write.
4. Indexing —Indexing is the process of providing an additional layer of organization to the data. This allows for faster retrieval of data during searches.
5. Data Integrity —Data integrity refers to the accuracy and consistency of the data in a database. It ensures that the data is accurate, up to date, and complete, and that any changes are properly reflected throughout the system.
6. Data Security —Data security is the process of protecting data from unauthorized access, modification, or deletion. It includes measures such as encryption, access control, and audit trails.
