MEAN
To arrange data in a particular manner.these manner or set of rules is defined in the data structure so that the data used in computer systems can properly used at necessary time.
A set structure is a data structure that stores unique elements, without any specific ordering. Sets typically provide operations for adding, removing, and checking for the presence of elements.
The lookup time for a HashSet data structure is typically O(1), which means it is constant time and does not depend on the number of elements in the set.

A map is a data structure that has a key set that "maps" onto a data set. Thus, the keys can be used to access the data. It is really similar to tables in real life with one column as the keys and one column as the data.
A concurrent object is an abstract data type that permits concurrent operations that appear to be atomic. It can be implemented as a data structure in shared memory and a set of algorithms that manipulate the data structure using atomic synchronization primitives.

How do you amend a data structure?
A primary data structure is a data structure that is created without the use of other data structures, whereas a secondary data structure relies on a primary data structure. A data structure is an organized collection of data elements.[NOTE: Be careful not to confuse the term data structure with the term data type. It is a common mistake. This answer addresses dat structures. Often people who ask about primary data structures or primitive data structures are really asking about primitve data types.]Here is an example where an array is a primary data structure and a binary tree is a secondary data structure based on the array:An array is a primary data structure -- it is a set of sequentially numbered data elements, such as an array of integers or an array of names -- name0, name, name2, ...A binary tree is a data structure where each element (called a node) has a data component and pointers to it's left and right sub-trees. [Think of a directory of folders, but each folder can only have two sub-folders.] We can create an and store an array of nodes to set up the tree in languages like C++ or Java.The root of the tree could be node 1 in the array, it would point to nodes 2 and 3. node 2 would point to nodes 4 and 5, while node 3 would point to nodes 6 and 7 .. and so on. generally node n point to nodes 2n and 2n+1. (You can start with node 0, but the math is a little easier if you start with node 1.)The binary tree in this case is the secondary data structure, while the undelying array is the primary data structure.
