Data Science and Big Data are interrelated concepts. Both of these concepts are key to using data to drive decision, innovation and value. The active development in the field of data implies the presence of data science and big data analytics. Data Science and Big Data, although related, are different concepts in the field of data analysis.

The focus of Data Science is on the application of statistical and machine learning methods to extract information from data and solve problems. This process includes collecting, cleaning, researching and interpreting data. Big Data refers to large and complex data where the capabilities of traditional data processing methods are not enough.

The key differences between Data Science and Big Data:

1. Concept and characteristics

Data science is an interdisciplinary field that integrates scientific methods, algorithms, and systems for extracting information from structured and unstructured data. Data is a key source for analysis and decision making. For this, statistical methods and machine learning algorithms are used.

Big Data includes structured (databases), semi-structured (xml) and unstructured (texts and images) data from many different sources. This technology allows for preliminary cleaning and processing, as well as analysis of huge amounts of data in real time.

2. Scope and methodology

Data Science uses statistical analysis, machine learning, data visualization, and exploratory data analysis to understand data patterns, predict, and find solutions.

Large datasets in Big Data are processed using infrastructure technologies. These include distributed storage and data processing systems. Parallel processing, scalability, etc. provide high-quality control of large volumes and high data transfer rates.

3. Goals

The goal of Data Science is to represent, extract knowledge and solve complex problems using data.

The goal of Big Data is to efficiently store, process and analyze huge amounts of data.

4. Usage

Data Science has been widely used in business intelligence to analyze customer behavior, market trends, and sales data. In healthcare, this technology is responsible for analyzing patient data for diagnosis and predicting treatment outcomes. Data Science also helps in clinical decision making and disease outbreak detection. In financial institutions, it helps to detect fraud, simulate risk and make informed investment decisions. The ability to analyze human language makes it possible to use applications such as chatbots, voice assistants, and machine translation.

Big Data enables insights into customer preferences, interests, behaviors, and buying patterns to improve products and inventory management, optimize pricing strategy, increase efficiency, and personalize marketing campaigns. This technology is used to analyze social media data, including user interactions, sentiment analysis, etc.

5. Benefits

The main advantage of Data Science is the ability to make informed decisions based on the information extracted from the data. This happens with the help of statistical analysis, machine learning methods and data visualization methods. Offers a wide range of applications as well as cost savings through efficient data management.

The main advantage of Big Data is the ability to process and analyze huge amounts of data, as well as gain valuable information and make decisions based on data. Provides a platform for advanced analytics and machine learning applications.

6. Disadvantages

The use of Data Science requires qualified specialists in the field. Pre-processing and cleaning of data requires significant time and resource costs. Ethical issues can also arise because Data Science deals with sensitive information.

Big Data also requires certain skills and experience in the field. Security and protection issues can be a problem when dealing with sensitive information.
