Structured data refers to information that is organized in a predefined format, making it easily searchable and analyzable. This type of data is often stored in databases or spreadsheets, where it follows a specific schema, such as rows and columns. Examples include customer names, addresses, and transaction records. Because structured data is highly organized, it can be processed quickly by computers and used for various applications, such as data analysis and reporting. Common formats for structured data include SQL databases and CSV files, which allow for efficient data management and retrieval.
