Structured and Unstructured Data and NoSQL
Databases 100% Verified
Structured data (also called relational data)
has a predefined data model. It can be mapped into prenamed fields. A US ZIP code can
be stored as a five digit string (example: 90210), a State as a two-character
abbreviation, such as CA, and so on.
Structured definition 2
Data that is the easiest to search and organize, since it is normally confined in rows and
columns, and its elements can be mapped into fixed pre-defined fields, is called
structured data. can follow a data model a database designer creates; entities can be
grouped together to form relations, and this makes structure databases easy to store,
analyze, and search; until recently, it was the only data easily usable for businesses.
Structured data is easily _______________________ and
_________________________________________.
easily stored and retrieved in a traditional relational database where the management
system applies logic to ensure information is in the correct format as it is written to disk.
structure data examples
Examples of structured data include financial data such as accounting transactions,
address details, demographic information, star ratings by customers, machines logs,
location data from smart phones and smart devices, etc.
Unstructured data
does not have a pre-defined data model. Thus, it cannot easily be categorized into the
pre-defined tables and rows of a relational database.
Satellite imagery, audio files, video files, or even emails may share common
characteristics, but these rich data types are not easily ingested, processed, or
analyzed with conventional database-related systems.
,Unstructured data defines 2
is information that cannot be stored in a row-column database and doesn't have an
associated data model. For instance, the text of an email message. The fact that it
wasn't structured made unstructured data more complicated to search, manage and
analyse, which became the reason companies widely rejected unstructured data until
recently when the recent proliferation of artificial intelligence and machine learning
algorithms made this a little easier to process.
Examples of unstructured data
Other examples of unstructured data include photos, video and audio files, text files,
social media content, satellite imagery, presentations, PDFs, open-ended survey
responses, websites and call center transcripts/recordings.

every record conforms to a pre-defined data model; if the arriving data does not meet
those definitions, then it cannot be stored without correction or truncation. Because of
this, structured data is often very verbose. This does have the advantage of being
extremely easy to parse and search using traditional software.

is more ambiguous. Without a predefined data model, you can store a far broader range
of rich data including images, sound, video, and text. As the scope for storage increases
and as data becomes more complex and dynamic, so too does the difficulty with which
you can search and analyze that information. Thankfully, modern data management
platforms like MongoDB Atlas exist that make storing and processing large volumes of
unstructured data easier than ever.
