Data Structures Tutorial

Data Structure Tutorial

The data structure is the concept of data being stored and organized in the computer memory and the process of retrieving the data from the data structures. It has a significant impact on the performance of data processing for various programming use cases. The data structure is the logical representation of data in the memory.

There are several categories available for data structure and implemented in computer programming. The programming languages support the use of several data structure methodologies while designing and development of the code. The data structure is the basic component for any complex and multiple data processing implementations.

Why do we need to learn Data Structure?

• We need to learn data structure to apply the best practices of computer science for developing efficient business solutions using computer programming.
• The data structure implementations need a good understanding of the relevant concepts and decisions to apply the best fit data structure for the particular requirements.
• The data structure knowledge is an added advantage for any software professional who deals with architecting, designing, developing and optimizing the applications using computer programming.
• Data structure helps the programmers to develop effective and reliable solutions.

Applications of Data Structure

• Data structure applications are implemented in several industry-specific solutions through sand and advanced programming. Data structure mainly divided into two categories such as primitive and non-primitive types.
• The primitive type data structure which is also known as data types in most of the programming languages such as integer, character, double types. These primitive data structures are useful to store the single-variable data in the run time of the applications.
• The non-primitive data structure is the advancement of computer science which is used to store and process multiple data in the applications.

The popular non-primitive data types are:

• Arrays
• Linked list
• Stack
• Queue
• Binary Trees
• Graphs
• These data structures are applied while developing and using computer algorithms for software solutions and product development.
• The data structures are closely associated with the computer algorithms which are applied through various programming like C and object-oriented programming like Java, C++, Microsoft C# programming.
• Moreover, the data structure extends with additional features, capabilities and the way of interacting with the data structure based upon the programming language.

Example

We will discuss Arrays as an Example of data structure which is a mostly used data structure through the programming languages. The array is a non-primitive linear data type, which holds similar data types and managed though an array index.

Following is a conceptual view of an arrays data structure containing the age of students enrolled for a course.

The above example of the array shown contains integer variable for students age for in an array declared as name ‘age_Students’ array. It stores 12 students’ age.

To search and retrieve the array element the index position will be used. For instance to access the 4th element of the array the data structure will be  age_Students[4] which will return the value of age 23 from the array. The array index starts with  0 or 1 as a base index depends upon the programming languages.

Prerequisites

The basic computer programming techniques and understanding of computer memory concepts.

Target Audience

The target audience for data science tutorials is computer science students, software professionals, product architects, and any IT professional who wants to learn data structure for career enhancement.
