A data structure is a way to organize information on a computer. Simple data structures include queues, stacks, and linked lists. More complex data structures include heaps, dictionaries, trees, and file Systems. Computer science courses teach students how to create and use such structures. Software engineering typically dismiss the coding that supports these structures and concentrates on how to use them.
In Computer science, an ontology refers to a data structure that models a given domain or conceptual space.
