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 a branching database.
Key Notes
- Objects need selecting to use in a branching database.
- Objects can be grouped using yes/no questions.
- Branching databases can be tested.
Vocabulary To Learn
- branching database: a digital tool for identifying objects using yes or no questions
- identify: establish what something or someone is
Common Mistakes To Avoid
- You can ask any question to add an item to a branching database.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Objects need selecting to use in a branching database. Objects can be grouped using yes/no questions.
2. Define this computing term and give one practical example. 'branching database'
a digital tool for identifying objects using yes or no questions. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: You can ask any question to add an item to a branching database. Correction: You need to ask yes or no questions to add items to a branching database. Open-ended questions are too difficult to represent in a branching database.
