Structured Data refers to information that is organized in a predefined format or schema, making it easily searchable and analyzable by both humans and machines. Typically, structured data is stored in databases or spreadsheets and is arranged in rows and columns, which facilitates its retrieval and manipulation. Common examples include contact lists, financial records, and inventory management systems. Structured data contrasts with unstructured data, which lacks a predefined format and includes text, images, and other forms of information that do not fit neatly into rows and columns.
