Concepts:
Investigate questions with yes/no answers
Identify attributes that you can ask yes/no questions about
Select an attribute to separate objects into two similarly sized groups
Explain that a branching database is an identification tool
Recognise that a data set can be structured using yes/no questions
Explain that a well-structured branching database will enable you to identify objects using fewer questions
Relate two levels of a branching database using AND
Suggest real-world applications for branching databases
Skills:
Create questions with yes/no answers
Choose questions that will divide objects into evenly sized subgroups
Repeatedly create subgroups of objects
Identify an object using a branching database
Retrieve information from different levels of the branching database
