Today in Computing with Mr Spracklen, Year 3 started a new unit of work.
Over the coming weeks we will be exploring 'Branching Databases'.
Today we explored what is meant by the term database? We learnt that a database is a collection of data organised in such a way that it can be searched, and information found easily. Database usually refers to data stored on computers.
A branching database is used to classify groups of objects. It is used to help identify the objects by answering questions with either ‘yes’ or ‘no’(like the game GUESS WHO).
Branching databases can also be called binary trees. They are called branching because each time a question is asked there can be two answers, making two branches. When you put all the questions and answers together in the database, it forms the shape of a tree (upside down).
We look forward to exploring more next week...
