Question
If names and email addresses are organized using a spreadsheet software, like Google Sheets or Microsoft Excel, which of type of data is this?
A. Structured data
B. True data
C. Semi-structured data
D. Unstructured data
Answer
A. Structured data
Explanation
Structured data is information that can be organized in rows and columns, such as names and email addresses, using a spreadsheet software like Google Sheets or Microsoft Excel.
If names and email addresses are organized using spreadsheet software like Google Sheets or Microsoft Excel, this would be considered structured data.
Structured data refers to data that is highly organized and formatted in a way that is easily searchable by simple search engine algorithms. It conforms to a pre-defined data model and is typically stored in relational databases or spreadsheets. In a spreadsheet, information is organized into rows and columns, with each column corresponding to a particular data attribute (like name or email), and each row corresponding to a specific data record.
Some key characteristics of structured data:
- Follows a rigid format and conforms to a fixed schema
- Stored in relational databases (SQL) or spreadsheets
- Each data field has a name and specific allowed values
- Easily searchable using simple algorithms
- Highly organized and formatted consistently
In contrast, unstructured data does not have a pre-defined data model or organized structure. Examples include free text, audio, images, and videos. This type of data is stored in non-relational databases (NoSQL) and is more difficult to search and analyze.
Semi-structured data falls between the two – it has some organizational properties but allows for some variation in the data. Examples include XML and JSON files.
So in summary, names and email addresses organized neatly in the rows and columns of a spreadsheet is a prime example of highly structured data, making A the correct answer. The rigid spreadsheet format allows the data to be easily searched and analyzed using straightforward methods.
