What is Big Data?

Big data is a term that describes the large volume of data, structured and unstructured, that floods a company on a day-to-day basis. Big Data is a term used for a collection of large and complex data sets that is difficult to store and process using the available database management tools or traditional data processing applications. The challenge includes capturing, curing, storing, searching, sharing, transferring, analyzing and visualizing this data.

Types of Big Data

Classification is essential for the study of any issue. Then Big Data is broadly classified into three main types, which are-

  • Structured

  • Unstructured

  • Semi-Structured

1. Structured

By structured data, we mean data that can be processed, stored and retrieved in a fixed format. It refers to highly organized information that can be easily and perfectly stored and accessed from a database by simple search engine algorithms. For example, the table of employees in a database of the company will be structured according to the details of the employee, their positions, their salaries, etc., will be present in an organized manner.

2. Unstructured

Unstructured data refers to data that does not have any specific form or structure. This makes it very difficult and slow to process and analyze unstructured data. E-mail is an example of unstructured data.

3. Semi-structured

Semi-structured data refers to data that contains the two formats mentioned above, that is, structured and unstructured data. To be precise, it refers to the data that, although they have not been classified in a specific repository (database), contain vital information or marks that segregate individual elements within the data.

Currently, the data in the form of e-mails, photos, videos, monitoring devices, PDF, audio, etc. they are also being considered in the analysis applications. This variety of unstructured data presents certain problems for storage, mining and data analysis.

3. Velocity

The term speed refers to the speed of data generation. The speed with which the data is generated and processed to meet the demands determines the real potential of the data. Big Data Velocity handles the speed at which data flows from sources such as business processes, application logs, networks and websites, social media, sensors, mobile devices, etc. The data flow is huge and continuous.
