Data retrieval refers to the process of obtaining information from a database or data storage system. It involves querying the data using specific criteria to extract relevant information, which can then be used for analysis, reporting, or decision-making. This process is essential in various fields, including business, research, and technology, as it allows users to access and utilize data effectively. The methods of data retrieval can vary, ranging from simple search queries to complex algorithms that analyze large datasets. Tools such as SQL (Structured Query Language) are commonly used to facilitate this process, enabling users to interact with databases and retrieve the information they need efficiently.
