Need help with coding - Vocabulary Database Program

Hey guys I am a beginner in coding, so I thought I might as well get help here.

I am trying to make a Vocabulary Database program, where the user can input his terms (and the corresponding definitions) and do different functions. The program should be able to add/edit term, search for term (and print corresponding definition), print alphabetical list, and also do a quiz (where a random definition is printed and the user must input the corresponding term).

I'd appreciate if you guys could help me get started (e.g. tell me what classes (data structures) i will need, and maybe some parts of the coding??)

Thanks guys
