The organizations that can manage all four Vs effectively stand to gain competitive advantage. Semi-structured data is one of many different types of data. Semi-structured data is data that has not been organized into a specialized repository, such as a database, but that nevertheless has associated information, such as metadata, that makes it more amenable to processing than raw data.. As you can see, HTML is organized through code, but it's not easily extractable into a database, and you can't use traditional data analytics methods to gain insights. But Big Data is only going to get bigger.

Therefore, it is also known as self-describing structure. Even documents, normally thought of as the epitome of semi-structure, can be designed with virtually the same rigor as database schema, enforced by the XML schema and processed by both commercial and custom software programs without reducing their usability by human readers. OEM (Object Exchange Model)[3] was created prior to XML as a means of self-describing a data structure.

This type of data is generally stored in tables. In view of this fact, XML might be referred to as having "flexible structure" capable of human-centric flow and hierarchy as well as highly rigorous element structure and data typing., Creative Commons Attribution-ShareAlike License, Programmers persisting objects from their application to a database do not need to worry about. For example, IoT sensors are expected to number tens of billions within the next five years. Semi-structured data is similar in nature to a semi-structured interview -- it's not as messy and uncontrolled as unstructured data, but not as rigid and readily quantifiable as structured data.

In semi-structured data, the entities belonging to the same class may have different attributes even though they are grouped together, and the attributes' order is not important. Structured Data: A 3-Minute Rundown for more clarification on structured vs. unstructured data. In addition to the firm structure for information, structured data has very set rules concerning how to access it. But for the sake of simplicity, data is loosely split into structured and unstructured categories. These are 3 types: Structured data, Semi-structured data, and Unstructured data. TechnologyAdvice does not include all companies or all types of products available in the marketplace. Free and premium plans, Content management system software. Structured data has a high level of organization making it predictable, easy to organize and very easily searchable using basic algorithms. JSON has been popularized by web services developed utilizing REST principles. “Whatever you call the storage mechanism, be it a data warehouse or data lake, and however you store the data, there’s going to be a combination of structured and unstructured data,” said Magne. Let's say you're conducting a semi-structured interview. Some examples of semi-structured data would be BibTex files or a Standard Generalized Markup Language (SGML) document. You end up with various columns and rows of data. Just consider the huge numbers of video files, audio files and social media postings being added every minute and you get an idea why the term big data originated.

That’s going to generate a lot of unstructured and semi-structured data.

Structured data is known as quantitative data, and is objective facts and numbers that analytics software can collect -- this type of data is easy to export, store, and organize in a database such as Excel or SQL. If almost all unstructured data actually contains some kind of structure in the form of metadata, what’s the difference?
