Examples of data structures: set, list (stack, queue, deque are
specialized examples), dictionary, tree, heap, matrix. A particular
organization of data with associated methods of operation upon them.
An abstract data structure is defined by the interface of the
methods -- what you can do -- rather than by the bit-by-bit
organization of any particular implementation of that structure.
Database: a collection of data on a particular topic using some data
Example: phone book, address book, a business database of suppliers
and customers, product and services, purchases and sales.
Relational database: a set of tables, each of which is a set/list of
records, each of which is a set/list or association of named fields.
Hope this help a bit.
