IB Computer Science Topic B.2.2 Processing Data with Rules Revision Notes (SL/HL) | RevisionDojo

Rules are instructions that tell a computer how to process data.
They are essential for ensuring that data is handled correctly and that the desired results are produced.

Note

Rules are often implemented as algorithms, which are step-by-step procedures for solving a problem or performing a task.
However, they can also be represented as mathematical formulae, tables of input/output values, etc.

Types of Rules

Validation Rules : Ensure data is correct and meets certain criteria.
Transformation Rules : Convert data from one form to another.
Calculation Rules : Perform mathematical operations on data.
Filtering Rules : Select specific data based on criteria.

Why Rules Are Important

Consistency: Rules ensure that data is processed in the same way every time.
Accuracy: Rules help prevent errors by validating and correcting data.
Efficiency: Automated rules save time and reduce manual effort.
