c - Data Structure for Library Management Project -

which data structure should used library management project?

there 5 operations:

• buy book
• buy new copy of book
• rent book
• return book
• delete copy of book

i know hash tables , avl-trees @ moment.

i started project avl, not sure if it's right choice.

it depends on want achieve(performance, extensibility, simplicity), above operations can implemented simple data structure array or linked list.

i recommand using simple data structure implement application first. when performance become problem, consider other data structures hashtable, avl tree, etc.
