What are the key differences between data mining and unsupervised learning techniques?
Data mining involves extracting patterns and insights from large datasets, often using supervised learning techniques where the model is trained on labeled data. Unsupervised learning, on the other hand, does not require labeled data and focuses on finding patterns and relationships in data without specific guidance. The key difference lies in the level of supervision and guidance provided to the algorithms during the learning process.
Discuss data mining and its role in database systems?
Data mining involves uncovering insights and patterns from large datasets to help make informed business decisions. It plays a crucial role in database systems by extracting valuable information from the stored data and discovering hidden patterns, trends, and relationships. This process helps businesses identify opportunities, predict future outcomes, and optimize decision-making.
Is it true that the process of observing data recognizing patterns and making generalizations about those patterns is known as deductive reasoning?
Yes
What is data retrieval?

Difference between data mining and database?
Data mining is the process of extracting hidden patterns from data. As more data is gathered, with the amount of data doubling every three years,[1] data mining is becoming an increasingly important tool to transform this data into information. It is commonly used in a wide range of profiling practices, such as marketing, surveillance, fraud detection and scientific discovery. Database is just the system that holds all the data. Or: "A database is a structured collection of records or data that is stored in a computer system." http://en.wikipedia.org/wiki/Database http://en.wikipedia.org/wiki/Data_mining
