Difference Between Data Science and Data Mining

Data Science: Data Science is a field or domain which includes and involves working with a huge amount of data and uses it for building predictive, prescriptive and prescriptive analytical models. It’s about digging, capturing, (building the model) analyzing(validating the model) and utilizing the data(deploying the best model). It is an intersection of Data and computing. It is a blend of the field of Computer Science, Business and Statistics together.

Applications of Data Science:

• Predictive Modeling: Predictive modeling is one of the most common applications of Data Science. It involves using statistical and machine learning algorithms to analyze historical data and identify patterns and trends to develop predictive models that can forecast future events or behaviors.
• Business Intelligence: Data Science is widely used in business intelligence to help companies make data-driven decisions. By analyzing large datasets, companies can gain valuable insights into customer behavior, market trends, and other factors that can inform business strategy.
• Fraud Detection: Data Science is used extensively in the finance industry to detect fraudulent activities. By analyzing transactional data, banks and financial institutions can identify unusual patterns and flag suspicious transactions for further investigation.
• Healthcare Analytics: Data Science is increasingly being used in healthcare to improve patient outcomes and reduce costs. By analyzing electronic health records, doctors and researchers can identify patterns and trends in patient data to develop more effective treatments and interventions.
• Natural Language Processing: Natural Language Processing (NLP) is a branch of Data Science that involves teaching computers to understand human language. NLP is used in a wide range of applications, from chatbots and virtual assistants to sentiment analysis and text summarization.
• Image and Video Analytics: Data Science is used extensively in image and video analytics to identify objects, people, and events in visual media. This technology is used in a wide range of applications, from security and surveillance to social media monitoring and marketing.
• Recommendation Systems: Data Science is used in recommendation systems to suggest products, services, and content based on users’ interests and behavior. These systems are widely used in e-commerce, media, and entertainment industries.
• Supply Chain Optimization: Data Science is used in supply chain management to optimize operations and reduce costs. By analyzing supply chain data, companies can identify inefficiencies and optimize their processes to improve efficiency and reduce waste.

Data Mining: Data Mining is a technique to extract important and vital information and knowledge from a huge set/libraries of data. It derives insight by carefully extracting, reviewing, and processing the huge data to find out pattern and co-relations which can be important for the business. It is analogous to the gold mining where golds are extracted from rocks and sands. 

Some of the different types of data mining services:

• Web mining: Web mining involves extracting useful information from the vast amount of data available on the internet. This can include analyzing web logs to identify patterns in user behavior, or using web scraping tools to collect data from websites.
• Text mining: Text mining involves analyzing unstructured text data to identify patterns and relationships. This can include sentiment analysis to determine the overall tone of a piece of text, or topic modeling to identify the main themes present in a large body of text.
• Audio mining: Audio mining involves analyzing audio data to identify patterns and trends. This can include speech recognition to transcribe spoken words into text, or audio fingerprinting to identify specific pieces of audio content.
• Video mining: Video mining involves analyzing video data to identify patterns and trends. This can include object detection to identify specific objects or people within a video, or facial recognition to identify specific individuals.
• Social network data mining: Social network data mining involves analyzing data from social media platforms to identify patterns and trends. This can include sentiment analysis to determine how people are talking about a particular topic, or network analysis to identify the relationships between different individuals or groups.
• Pictorial data mining: Pictorial data mining involves analyzing visual data, such as photographs or diagrams, to identify patterns and relationships. This can include image recognition to identify specific objects or features within an image, or data visualization to help people understand complex visual data.

Data science and data mining are related but distinct fields that involve the extraction of useful information from large data sets.

Data science is a broad field that encompasses various techniques and tools for analyzing and interpreting data. It involves using statistical, machine learning, and programming techniques to extract insights and knowledge from data. Data scientists use data to build predictive models, visualize data, and communicate findings to stakeholders.

Data mining, on the other hand, is a specific technique used within data science to extract patterns and knowledge from large data sets. It typically involves using algorithms and statistical methods to discover hidden patterns and relationships in data. The goal of data mining is to identify useful information from data, such as customer behavior, product preferences, and market trends, that can be used to make better decisions.

In summary, data science is a broad field that includes data mining as one of its many techniques, but also includes other techniques such as statistical analysis, machine learning, and visualization. Data mining is a specific technique used to extract patterns and knowledge from large data sets.
