What is data?
Data is essentially a collection of anything from numbers and figures to text and symbols. It is basically unprocessed information.
Example of data:
- Temperature records throughout the day noted down in a record book
- Daily attendance of students in class recorded in attendance book
- Body measurements noted by tailor for stitching your new suit
Note: data should be stored either in digital or physical format.
Data ——–> Processed——-> get Information
Let’s see what data is comprised of,
- Data could be numbers, text, images, videos, social media posts, email etc…
Let’s see different kinds of data,
- If data is placed in table (also known as database comprised of rows and column) then we call it as structured data
- Eg: Data stored in excel sheets
- If data is just stored as text, email or social media post, here there is no structure to store the data. So we call this as un-structured data
- Eg: your thoughts scribbled on notepad, email with text and images etc.
- Ok now, what if data is a mix of both structured and structured data? Does it exist? Yes this is known as semi-structured data
- Eg: Jason file
