What is the difference between a data structure collection and a table in the context of data storage?

A collection is a data structure in memory that stores a set of elements (for example, a list, set, or dictionary). It is designed for working with data in the application's RAM.

A table, on the other hand, is a data storage structure in a database, where data is organized into rows and columns. A table is intended for long-term storage and management of large volumes of data.

Main differences:

• Collection is temporary, in-memory, used for data processing during program execution.
• Table is a permanent storage, data is saved on disk.
• Table supports queries, indexes, and relationships between data.

Example: in iOS, a collection can be an array [1, 2, 3], while a table is a table in Core Data or SQLite, where these numbers are stored in a database.
