Introduction: Importance of Data Structures for the Information Management Professional Engineer Exam
Data structures and algorithms are core evaluation elements in the Information Management Professional Engineer exam. This is because they are essential knowledge for verifying efficient system design and problem-solving skills. In particular, the ability to select optimal data structures and implement algorithms that ensure the best performance in a rapidly changing IT environment is becoming increasingly important. This post aims to provide practical assistance in preparing for the Information Management Professional Engineer exam by deeply analyzing everything from the basic principles of data structures to the latest sorting algorithm trends.
Core Concepts and Principles
A data structure is a structure for efficiently storing, managing, and accessing data. Representative data structures include arrays, linked lists, stacks, queues, trees, and graphs. Each data structure provides efficient performance for specific operations, and it is important to select a data structure that matches the characteristics of the problem. Sorting algorithms are algorithms that rearrange data in a specific order; examples include Bubble Sort, Insertion Sort, Selection Sort, Merge Sort, and Quick Sort. Each sorting algorithm differs in terms of time complexity and space complexity, and performance varies depending on the size and distribution of the data.
Bubble Sort
Bubble Sort is the most basic sorting algorithm, operating by comparing adjacent elements and swapping them if they are not in the correct order. This process is repeated from the beginning to the end of the data, and in each iteration, the largest element moves to the end. Although its time complexity is O(n^2), making it inefficient, it is widely used for educational purposes due to its simple implementation.
Latest Trends and Changes
As of 2025, the field of data science is rapidly changing with the introduction of Edge AI, Generative AI and AI Agents. In particular, the advancement of Large Language Models (LLMs) is revolutionizing data processing and analysis methods, and new challenges are emerging, such as addressing misalignment in the medical field. In addition, there are reports that the new sorting algorithm JesseSort performs faster than Powersort, and C++ remains a strong choice in the AI era for high-performance computing and low-level control.
Practical Application Strategies
Data structures and sorting algorithms are used as core components of various IT systems, including database systems, search engines, and operating systems. For example, database systems use the B-tree data structure to support efficient data retrieval, and search engines use hash tables to implement fast searching. In addition, operating systems use various sorting algorithms to perform process scheduling and memory management. In actual system development, it is necessary to select the optimal data structure and algorithm considering the characteristics and requirements of the problem.
