What data organization is described as data stored in rows and columns?

• A. Unstructured Data
• B. Cross-sectional data
• C. Structured Data
• D. Time series data

Answer: (C)

Data stored in rows and columns is structured data. This format uses a predefined schema that defines what each column represents and what type of data it holds, so every row is a complete record and each column holds a specific attribute. This organization makes it easy to query, filter, sort, or join records using tools like SQL or spreadsheets. For example, a table of customers might have columns like CustomerID, Name, Email, and Balance, with each row representing one customer. The row-column layout also supports indexing and data validation, which helps ensure consistency and fast retrieval. Unstructured data, such as emails, documents, images, or multimedia, doesn’t adhere to a fixed row-column schema and is harder to query with simple table-based methods. Time series data refers to observations indexed in time order and can be stored in a table, but the defining feature is the time aspect rather than the general row-column structure. Cross-sectional data describes observations at a single point in time across units, which can also be stored in a table, but again the emphasis is on the snapshot nature rather than the schema.
