Data retrieval is the process of obtaining information from a database or storage system. It involves using specific queries or commands to access and extract the desired data. This can include searching for records, filtering results, or sorting information based on certain criteria. In many cases, data retrieval is facilitated by software tools or programming languages, such as SQL for relational databases. Efficient data retrieval is crucial for decision-making in various fields, including business, healthcare, and research, as it allows users to quickly access relevant information to support their needs.
