Unstructured Data

Back to Glossary

What is Unstructured Data? 

Unstructured data refers to any data that does not have a predefined data model or format. It is essentially raw data that has not been organized or processed in any specific way, and can take various forms, including text documents, images, videos, social media posts, and sensor data. Unlike structured data, which is organized into a fixed schema or data model, unstructured data does not conform to any specific schema or structure, making it more difficult to manage and analyze using traditional data analysis tools.

Businesses are looking to applications of AI, such as machine learning and natural language processing techniques, to extract valuable insights from unstructured data. These methods can help identify patterns and relationships within the data. Data lakes and cloud storage systems are becoming increasingly popular for warehousing large volumes of unstructured data. They offer a more cost-effective and scalable solution than traditional relational databases.

Structured vs unstructured data

Structured and unstructured data are two fundamental data types that differ in format, storage, analysis, and accessibility. Below, we explore both data types across these four key areas. 


Structured data is organized and stored in a predefined format, such as a relational database, and conforms to a fixed schema or data model. Structured data is usually quantitative, with well-defined fields and values. Unstructured data, conversely, does not follow a fixed schema or data model or conform to a predefined structure or format. Unstructured data can take many forms, such as text, audio, video, images, social media posts, emails, and sensor data. Semi-structured data contains elements of both structured and unstructured data and has a flexible schema that can evolve, but it still has some structure, such as tags or labels.

Text-based unstructured data: Unstructured data in written form, such as emails, social media posts, news articles, and documents, falls under the category of text-based data. Such data is replete with qualitative information like sentiments, opinions, and contextual cues, making it a crucial source of insight for businesses.

Audio and video data: Audio data includes unstructured data in a sound format, such as voice recordings, music, and podcasts. Businesses can apply natural language processing techniques to extract valuable insights from this type of data.

Video data includes things like TV shows  and online videos. Video data can be processed using computer vision techniques to identify objects, people, and other features within the video, making it useful for applications such as security and surveillance.

Images and graphics: Image data includes  still images, such as photographs, charts, and diagrams. Businesses can again leverage computer vision techniques to process such data and identify objects, shapes, and patterns within the image. This makes image data useful in medical imaging and quality control applications.


A data warehouse or relational database typically stores structured data, which provides a consistent and reliable structure for storage. Unstructured data is often stored in data lakes or object storage systems like Amazon Web Services (AWS) S3, Microsoft Azure Blob Storage, Google Cloud Storage, IBM Cloud Object Storage, Snowflake, and Databricks. Data lakes are large repositories of raw data stored in their native format, allowing faster and more flexible processing and analysis. Object storage is a distributed data architecture that is designed to handle large amounts of unstructured data at scale.


Structured data is considered generally easier to analyze using a structured query language (SQL) or MS Excel. Unstructured data often requires more specialized tools or techniques to extract insights. Machine learning and natural language processing techniques can help identify patterns and relationships within unstructured data, enabling businesses to derive meaningful insights and make informed decisions.

Benefits of unstructured data

Unstructured data can provide valuable insights for businesses that are difficult to obtain from structured data alone. According to one finding from CIO, unstructured data accounts for around 80% of all data generated.  If nothing else this highlights the sheer volume of raw data that might contain useful insights for analysts.   

By leveraging machine learning and natural language processing techniques, businesses can extract insights from unstructured data, enabling them to make informed decisions and gain a competitive advantage. 

Customer Experience

Additionally, unstructured data can be used to improve customer service and engagement, operational efficiency and cost reduction. Marriott Hotels use unstructured data from Amazon Echo devices. Guests can ask Alexa to handle requests that reception staff would deal with previously. The chain saves on staff costs while gathering data on customer preferences, needs, and concerns. 


McKinsey reports that companies that use unstructured data analytics to optimize their operations can increase productivity by up to 30%. The streaming giant Netflix uses machine learning to analyze customer behavior and preferences based on viewing history, search queries, and other unstructured data sources. Netflix can make personalized recommendations and create content that appeals to its audience, ultimately driving customer retention and satisfaction.

Customer Behavior

Image and video data can also help businesses. Retailers can use image recognition technology to analyze customer behavior and preferences based on images captured by in-store cameras or uploaded to social media. Macy’s is leveraging image recognition technology to analyze customer images and identify trending fashion styles and colors.

Unstructured data is a crucial resource that enables data-driven businesses to understand their customers in-depth and optimize their processes for improved operational efficiency. With the increasing availability of data visualization tools and advanced analytics techniques like natural language processing and machine learning, companies can extract valuable insights from unstructured data and make informed decisions that drive growth and success.

Emerging trends in unstructured data management and analysis

As vast amounts of unstructured data continue to be generated, there is a need for modern technologies and techniques to help manage and analyze this data more efficiently. 

Edge Computing

One of the most prominent trends in unstructured data management is edge computing, which enables businesses to process data locally and more quickly, resulting in faster processing speeds and reduced network latency. Cloud-based solutions are another trend, providing companies with scalable, flexible, and cost-effective storage and processing options for their unstructured data needs.

Data Visualization

Moreover, data visualization is crucial to understanding unstructured data, enabling businesses to gain valuable insights through graphical data representations. Advanced analytics, including machine learning and natural language processing, are frequently used to identify patterns and relationships within unstructured data.

Web 3.0

In addition, Web 3.0 and the metaverse are expected to drive significant advancements in unstructured data management and analysis, providing businesses with innovative opportunities to leverage unstructured data. Virtual reality (VR) is also becoming increasingly popular in data management, allowing real-time data analysis and decision-making.

These emerging trends give businesses powerful tools to extract insights from vast data pools. However, it is essential to note that while technology plays a significant role in unstructured data management, human nuance is still crucial. Data analysts and subject matter experts are needed to interpret data accurately, draw meaningful insights, and make informed decisions that can drive business growth.
