# Databases

Databases are hard to use and not generally suggested for internal assessments, as it is difficult to come up with an original idea that is also within the ability and time of a student to accomplish. 

However, extracting data from a database and analysing it graphically is one of the options for the internal assessment. In physics, the most likely and common topic is astrophysics.
