3. Data and Testing 

Overview

Data forms the foundation of all IT systems, and this topic distinguishes between raw data and processed information. 

You'll explore various data types (alphanumeric, boolean, numeric, text) and their applications in different contexts. 

The topic covers essential data collection methods, both primary (surveys, interviews) and secondary (books, websites, government statistics), plus storage solutions from local drives to cloud platforms. 

Understanding validation, verification, and testing methodologies ensures data accuracy and system reliability through proper quality assurance processes.

You will also use these features and tools when completing your coursework.
