Question
Which of the following is an example of structured data?
A. Videos
B. Flight schedules
C. Movie reviews
D. Social media posts
Answer
Of the options provided, flight schedules are the example of structured data.
B. Flight schedules
Explanation
Structured data is typically information that can be organized in rows and columns, such as flight schedules that include departure times, arrival times, and flight numbers.
Structured data refers to data that is highly organized and formatted into a well-defined schema, typically in the form of tables with clear rows and columns. Each data element has a precise value and fits neatly into a pre-defined field. Structured data is highly organized and easily searchable by simple search algorithms.
Some key characteristics of structured data:
- Stored in relational databases (rows and columns)
- Conforms to a rigid, pre-defined data model
- Follows a consistent order and format
- Each field has a name and single value
- Easily searched using SQL and basic search algorithms
Flight schedules are a classic example of structured data. The data has clear fields like flight number, origin, destination, departure time, arrival time, etc. Each data point fits into a defined field. The data follows a consistent structure that allows it to be stored in a relational database and easily queried.
In contrast, videos, movie reviews and social media posts are all examples of unstructured data. They contain data in an unorganized format – freeform text, images, audio, etc. This data doesn’t fit neatly into pre-defined fields and can’t be stored in a relational database. Unstructured data is more difficult to search and analyze.
So in summary, of the given options, flight schedules are the only example of structured data, while videos, movie reviews and social posts are all unstructured data types. The rigid, organized format of flight schedule data makes it a quintessential example of structured data.
