From abstract data types in wiki, I'm reading about two types: collection and container. Can anyone supply a better detailed difference between the difference between the two? https://en.wikipedia.org/wiki/Container_(abstract_data_type) https://en.wikipedia.org/wiki/Collection_(abstract_data_type)
As I understand...
Collection is an abstract data type.
- it is a grouping of some variable number of data items. Collections can be further specialized into Linear Collections, Associative Collections, and Graph Collection.
- "Collection does not prescribe a specific implementation as a concrete data structure, though often there is a conventional choice (see Container ) "
Container is an abstract data type.
- they store objects in an organized way that follows specific access rules.
- seem to have more explicit properties/methods i.e CRUD operators, etc.
From what it looks like, Collection is definitely more abstract compared to containers. Collection seem to define a general relation on the insides of how data are related to each other in order/or lack there of. The container ADT is also very similar, but I'm guessing container is just a slightly more detail abstraction for defining what essential operations is needed so that almost all lower more specific ADT can be implemented using containers.
side note: "Collection does not prescribe a specific implementation as a concrete data structure, though often there is a conventional choice (see Container ) " - then what is not a conventional choice?
