# About Types Of Data Structures, Classification Of Data Structures

**Types of data structure**

In all, it can be seen that data structures are highly beneficial, not least because they allow the most basic pieces of computer software to function correctly. Without data structures, we would not have the modern computer of today.

**Data structures can be classified as**

- Simple data structure
- Compound data structure
- Linear data structure

Non linear data structure

**Simple Data Structure:**

**Compound Data structure:**Compound data structure can be constructed with the help of any one of the primitive data structure and it is having a specific functionality. It can be designed by user.

**Linear data structure****Non-linear data structure**

**Linear data structure:**

**For example:**

*Stack, Queue, Tables, List, and Linked Lists*.

**Non-linear data structure:**

Operations applied on non-linear data structures: The following list of operations applied on non-linear data structures.

- Add an element

- Delete an element

- Traverse(reaching to that point)

- Sort the list of elements

- Search for a data element

Non-linear data structure can be constructed as a collection of randomly distributed set of data item joined together by using a special pointer (tag). In non-linear Data structure the relationship of adjacency is not maintained between the Data items.

**Some Definitions**

**1.Algorithm**

**2.Data Type:**

*int, char, float, double.***3.Abstraction**

**abstraction.**

**As an example**,

Consider a program that manages the student records. The head of the Bronco Direct comes to you and asks you to create a program which allows administering the students in a class. Well, this is too vague a problem. We need to think about, for example, what student information is needed for the record? What tasks should be allowed? There are many properties we could think of about a student, such as name, DOB, SSN, ID, major, email, mailing address, transcripts, hair color, hobbies, etc. Not all these properties are necessary to solve the problem. To keep it simple, we assume that a student’s record includes the following fields: (1) the student’s name and (2) ID. The three simplest operations performed by this program include (1) adding a new student to the class, (2) searching the class for a student, given some information of the student, and (3) deleting a student who has dropped the class. These three operations can be furthermore defined as below:

- ADD (stu_record): This operation adds the given student record to the collection of student records.
- SEARCH (stu_record_id): This operation searches the collection of student records for the student whose ID has been given.
- DELETE (stu_record_id): This operation deletes the student record with the given ID from the collection. Now, we have modeled the problem in its most abstract form: listing the types of data we are interested in and the operations that we would like to perform on the data. We have not discussed anything about how these student records will be stored in memory and how these operations will be implemented. This kind of abstraction defines an
**abstract data type (ADT).**
