Adding and deleting data from a database can be straightforward, especially with well-structured databases and user-friendly interfaces. However, it can become complex depending on the database design, relationships between tables, and constraints like foreign keys. Proper permissions and understanding of the database management system (DBMS) are also essential to ensure data integrity during these operations. Overall, while basic operations are generally easy, complexities can arise in larger or more intricate databases.
