a diagram where data is organised into a structure that is like an upside-down tree

a set of people or objects placed together

Making groups

Computing

This unit develops pupils' knowledge of what a branching database is and how to create one. They will use yes/no questions to gain an understanding of what attributes are and how to use them to sort groups of objects. Pupils will create an identification tool using a branching database.

Organising data using databases

a structure that starts with one group and splits it into smaller groups

a structure where objects are placed randomly

a structure that starts with many groups and ends with one group

What is the purpose of a branching tree diagram?

to describe objects and split them into groups

Objects can belong to both the 'yes' and 'no' groups.

Objects can belong to neither the 'yes' nor the 'no' group.

Objects can belong to either the 'yes' or 'no' group, but not both or neither.

Objects are not split into groups by yes/no questions.

Which statement about yes/no groups is correct?

Which way does a branching tree diagram grow?

a question that can be answered with yes or no

a thing that is uniquely identifiable and has attributes
