What Are the Five Major Differences Between Structured and Unstructured Data?

Structured data can be easily organized and follows a specific format, while unstructured data is often presented as images, audio files, or text. Both types can be easily analyzed with spreadsheet programs, such as Excel. However, if you’re looking for information without a rigid structure, unstructured data is probably the best choice. This article will discuss the Structured vs Unstructured Data: 5 Key Differences | Resolute.ai and which format would be best for your organization.

Structured data is easily organized.

There are two types of data: structured and unstructured. Structured data is formatted and easily searchable in relational databases. On the other hand, unstructured data is not well organized or pre-defined. It can be stored in various formats, including text, images, and audio files. If the information is not structured, it may be difficult to process. Both types are equally helpful for different purposes.

Often, structured data is described as quantitative data. This is because the data can be organized by following rigid rules. On the other hand, unstructured data is highly subjective and cannot be reduced to a relational database. This type is also called semi-structured because it contains elements of both types. For example, semi-structured data can be used for marketing purposes, while unstructured data can be used for policy monitoring.

Structured data follows a rigid format.

Unstructured data is messy and hard to organize, while structured data follows a more rigid structure. Spreadsheets and relational databases are examples of structured data. A typical example is a spreadsheet including names, dates, credit card numbers, and stock information. On the other hand, it might be text or numbers. Whether a sentence is structured is based on semantics.

Business organizations rely heavily on data to run their operations. Depending on the nature of the business, this information can come in many different forms, ranging from Tweets to financial information to stock flow. But one problem with unstructured data is that most of it aren’t quantifiable. In addition, some of it may not be available in quantitative forms, such as a video clip or a customer’s feelings. On the other hand, structured data makes this information much easier to interpret and manage.

Structured data is more reliable.

You’ve probably heard the expression, “structured data is more reliable.” This is certainly true when creating machine learning models for content. It makes things easier for a search engine to understand the context. The data can be structured into properties or types, like “John Smith” is a name and “Software Engineer” is a job role. For example, you might want to use structured data to identify sales leads and then tie the results back to the company’s value proposition.

The difference between structured and unstructured data can be seen in how each format is categorized. Generally, structured data are presented as numbers or text, while unstructured data is presented in less easily categorized shapes. This can be helpful when you’re trying to determine the cause of a malfunctioning machine, but it’s less reliable for other uses. 

Structured data is more flexible.

When it comes to storage, unstructured data trumps structured data. Structured information is typically stored in a database with a fixed format, whereas unstructured data can be stored in various designs and sizes. And unlike structured data, unstructured data does not have a pre-defined data model, making it more flexible and adaptable. In addition, it is much easier to manage, which makes it the preferred choice for large-scale data stores.

Semi-structured data is different from structured data. It doesn’t follow a relational database’s tabular structure but has tags and metadata to separate semantic elements. It’s easier to handle and scale because it doesn’t follow a strict relational database structure.

Unstructured data is difficult to analyze

Many organizations struggle with unstructured data because it is difficult to index and process using traditional database tools. Examples of unstructured data include text, audio and video files, social media posts, and mobile activity. Because unstructured data is not formatted into tables, it cannot be stored in a relational database. Non-relational databases are the most appropriate solution to manage large volumes of unstructured data. Unstructured data can be stored in a data lake, which is a form of storage used by many companies to store unstructured data.

To make unstructured data more usable, organizations must first preprocess it. This process involves reducing noise, removing irrelevant information, and cutting the data into manageable pieces. Preprocessing data also consists in breaking down the data into opinion units. This process requires more than a data analysis tool, however. For example, organizations must invest in a data storage architecture and develop the proper data visualization tools to summarize the data in easily readable, actionable charts.
