Exploring Data

Exploring Data


Through stimulating activities, students learn the vocabulary associated with databases including an introduction to handling CSV files. Students perform real data collection and enter details into the live database. Moving-on, student design database tables for a given purpose and learn about suitable fieldnames and data types for storing data. They then build a database table from first principles using designs, and learn how to import data from external files. After watching an informative video tutorial on creating queries, students carry out increasingly challenging practical exercises. Student then move onto consider the function and suitability of different input and output devices, researching real world costs in the process. Finally, students complete the unit, integrating their learning from the modelling unit to produce a user guide for their database and spreadsheet models for assessment.
