Description: The union of sets is a fundamental operation in set theory that combines multiple sets into a single one. This operation allows for the aggregation of elements from different sets, eliminating duplicates to form a new set. The union is commonly represented by the symbol ‘∪’ and is one of the basic operations that can be performed on set data structures. This operation is particularly useful in applications where data from different sources or categories needs to be combined, facilitating the analysis and manipulation of information. The union of sets is performed efficiently in various programming languages and databases, allowing for quick results even with large volumes of data. This ability to effectively handle sets is one of the reasons why set operations are popular in applications requiring high performance and scalability.
