Flat File Data Bases
Used for only one kind of entitys. Can be used to store only students or forms, not both easily as errors can be occured because you need to repeat information. Also not storage efficient. Every time you add an item you need to add all ther information. Can cause redundant Data and inconsitencey.
Relational Data Bases
Uses keys that connect certain data together. Keys will never be dupplicated. Goreing keys will be from a sperate table.
Have a table with all the forms data stored, and mearley state the students key to be the forms, thereby giving the students a link to all the centrall data, allowing for one set of form information to be linked to all of it.
