- How does the hierarchical data model address the problem of data redundancy?
The hierarchical model divides the data into parents and children with the system working on the principle that each child can have only one parent but each parent can have an infinate number of children - thus supporting one-to-manyrelationships.This means that data redundency is reduced as a relationship can be established between entities e.g. in a school system each course would be a parent, with each student being the child, and each grade being the child of the student.This would allow you to createa one-to-many relationship between the students on each course and the grades for each pupil.However this system is not ideal for this scenario, as if a student was enrolled on more than one course their details would have to be duplicated for each course.To deal with this many-to-many relationship you would need to create a relational database, creating a studentcourses entity with a one to many relationship occurring between both it and a student entity and it and a courses entity
