Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
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.
Lesson Summary
You will learn to create questions that have yes/no answers.
Key Notes
- Some questions can only have yes or no answers.
- Questions can be made up about a specific group of objects.
- A group of objects can be split using a yes/no question.
- An object is something that is uniquely identifiable and has attributes.
Vocabulary To Learn
- object: something that is uniquely identifiable and has attributes
- attribute: a thing or quality about an object, like its colour or size
Common Mistakes To Avoid
- Objects can only be grouped in one way.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Some questions can only have yes or no answers. Questions can be made up about a specific group of objects.
2. Define this computing term and give one practical example. 'object'
something that is uniquely identifiable and has attributes. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Objects can only be grouped in one way. Correction: Objects can be grouped in multiple ways using different attributes to create groups.
