Final answer:
The violation of the second normal form occurs when tables combine data that should be separated into different tables. By separating the data, we can eliminate partial dependencies and ensure each table contains only relevant and non-redundant information.
Step-by-step explanation:
The violation of the second normal form occurs when tables combine data that should be separated into different tables. This violation typically happens when a table's records are not entirely dependent on the primary key but on a part of it called a partial dependency. For example, if we have a table called 'Students' with columns such as 'Student ID', 'Student Name', and 'Course Name', the 'Course Name' column violates the second normal form because it should be stored in a separate table called 'Courses' with its own primary key. By separating the data into different tables, we can eliminate partial dependencies and ensure that each table contains only relevant and non-redundant information.
