∙ 7y ago
Directed data mining involves using predefined goals or objectives to guide the analysis and modeling of data. In contrast, undirected data mining aims to discover patterns or relationships in data without specifying a particular outcome in advance. Directed data mining is typically used for tasks such as classification and regression, while undirected data mining techniques include clustering and anomaly detection.

What diff between the database and database system?
A database is a collection of organized data, while a database system is a software application that manages, stores, and retrieves data from that database. The database system includes software for managing the database, as well as tools for interacting with the data, ensuring data integrity, and controlling access to the data.
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.
What is the name of the system database that contains descriptions of the data in the database?

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
