Study Hub
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 plan the structure of a branching database.
Key Notes
- Branching database structures can be planned.
- A series of questions can be used to identify a unique object.
- Objects can be compared using attributes.
Vocabulary To Learn
- plan: a design to show what something will look like in the future
- compare: looking at two or more things to see what is the same or different
Common Mistakes To Avoid
- Any question can be used to create a branching database successfully.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Branching database structures can be planned. A series of questions can be used to identify a unique object.
2. Define this computing term and give one practical example. 'plan'
a design to show what something will look like in the future. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Any question can be used to create a branching database successfully. Correction: A good question should split the data evenly to make sure the number of questions required to reach what is being looked for is minimised.
