Keys


In the context of data structures and computer science, keys refer to identifiers used to sort, retrieve, or manage data within an array, database, or other data storage system. Keys are crucial for efficient data access and manipulation, serving as a unique identifier for each element or record in the data set. In databases, keys ensure data integrity and can be categorized into different types, such as primary keys (unique for each record), foreign keys (referencing primary keys of other tables), and composite keys (formed by combining two or more columns). In data structures like hash tables and trees, keys are used to organize data in a way that optimizes searching and retrieval operations. The concept of keys is fundamental to understanding how data is structured, accessed, and maintained in computer applications and systems.
