Structured vs Unstructured Data: Compared and Explained

In my previous blog post I talk about what data is. In this article, we will see what different types of data there are. The distinction between different types of data is important because it impacts how data can be stored, how it should be organized and how easy it is to process and analyze it. This applies to all data, regardless of what sector we are looking at. In this article we will look at. Recall from this blog post that put very simply, data is nothing else than information stored in digital format.

What is structured, semi structured and unstructured data?

In computer science, a data structure is a particular way of organising and storing data in a computer such that it can be accessed and modified efficiently. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. For the analysis of data, it is important to understand that there are three common types of data structures:. Structured data is data that adheres to a pre-defined data model and is therefore straightforward to analyse. Structured data conforms to a tabular format with relationship between the different rows and columns. Common examples of structured data are Excel files or SQL databases.

Unorganized information is costly…and for many organizations, a majority of their data is just that — unstructured and unorganized. Before you can properly procure and manage your data, you must first understand the difference between structured and unstructured data. At first glance, the answer is as simple as it appears. Structured data is organized…and unstructured data is not. Most companies are familiar with structured data, as it currently represents most, if not all of, their current available information. To visualize structured data, think of it as the digital equivalent of a highly organized filing cabinet, in which every record has been labeled, organized, and maximized for retrieval. Unstructured Data, on the other hand, is often raw and highly unorganized.

Unstructured data or unstructured information is information that either does not have a pre-defined data model or is not organized in a pre-defined manner. Unstructured information is typically text -heavy, but may contain data such as dates, numbers, and facts as well. This results in irregularities and ambiguities that make it difficult to understand using traditional programs as compared to data stored in fielded form in databases or annotated semantically tagged in documents. As of [update] , IDC and Dell EMC project that data will grow to 40 zettabytes by , resulting in a fold growth from the beginning of The earliest research into business intelligence focused in on unstructured textual data, rather than numerical data. Luhn were particularly concerned with the extraction and classification of unstructured text. Techniques such as data mining , natural language processing NLP , and text analytics provide different methods to find patterns in, or otherwise interpret, this information.

Explaining what structured data is and what it means quickly leads to its counterpart, which is unstructured data. Examples of unstructured data include analogue or digital text documents, audio files, videos, and images. The challenge with such data is that it is hard to organise or manage into further forms. Only structured data can be managed and used efficiently. This is especially true for electronic data processing solutions and Internet applications.

Use of this web site signifies your agreement to the terms and conditions. Unravelling unstructured data: A wealth of information in big data Abstract: Big Data is data of high volume and high variety being produced or generated at high velocity which cannot be stored, managed, processed or analyzed using the existing traditional software tools, techniques and architectures. With big data many challenges such as scale, heterogeneity, speed and privacy are associated but there are opportunities as well.

Unstructured Data Unstructured data encompasses everything that isn't structured or semi-structured data. Text documents and the different kinds of multimedia files audio, video, photo are all types of unstructured data file formats.
