The transformation introduces the possibility of having a MAJOR associated with multiple MINORS in Table2, which was not explicitly represented in the original STUDENT table schema. Additionally, if the original STUDENT table included unique student identifiers or other attributes, this information would be lost in the transformation. The separation into two tables without a clear linkage for individual students' minors introduces ambiguity and potential data integrity issues, thus leading to loss of specific information and introduction of potentially meaningless associations between majors and minors without context to specific students.
