During a day’s business, organizations create, use, and save a surprisingly massive volume of data. This data is generated and collected from diverse sources, including social media, online transactions, and IoT sensors.
Given this increasing data generation and collection trend, many businesses feel that traditional database administration technologies are no longer adequate to manage and analyze this massive volume of data.
This is why organizations are using Big Data databases.
Big Data databases are designed to meet the challenges presented by growing data volumes.
These databases can gather, store, manage, and analyze massive amounts of structured, semi-structured, and unstructured data. The database platforms allow users to extract significant insights and make informed decisions based on these insights.
Big Data databases come with the latest data management and analytics capabilities that allow businesses to take full benefit of their extensive data store. These platforms can handle and use data with attributes such as high volume, variety, high velocity, and multiple relationships between data items.
In this article, we’ll discuss the concept of Big Data databases, their distinguishing characteristics, and the benefits they offer. But, before we discuss these databases in more detail, it is essential to understand what is data and Big Data.

What is Data and Big Data?
Data is a collection of raw and unorganized facts, statistics, or information, generally expressed in multiple forms, such as numbers, text, sensor inputs, and graphics.
Big Data, on the other hand, refers to extraordinarily vast and complicated data collections. In contrast to traditional data, Big Data has high Volume, Diversity (multiple types and formats of data items), and Velocity (the speed at which data items are created and processed). In addition, Big Data has complex relationships at several levels.
Types Of Big Data
An important characteristic of Big Data is the huge flexibility in what is considered Big Data, based on the three main types of sources and makeup of data items.
Let’s discuss the specifics of Big Data types:
Structured Data
Structured data refers to well-organized data that follow a predefined format. This makes it easy to store and query in traditional relational databases. In most cases, this data type is properly organized into rows and columns with fixed data types.
Structured data is also called relational data. When storing it in a relational database, you can divide it into numerous tables to improve data integrity by establishing a single record representing an object.
Table constraints are used to enforce relationships between data items.
The commercial value of structured data is determined by how well an organization can analyze it using its existing systems and procedures.
Data in relational databases, spreadsheets, and structured text files are examples of structured data.
Unstructured Data
Unstructured data lacks a set format and does not fit appropriately into the typical relational database architecture. This data type is more challenging to process and analyze since it doesn’t follow a strict schema.
Unstructured data does not adhere to any particular schema or set of data design principles. In all cases, its layout is chaotic, and database designers find it challenging to fit it into a predefined data classification scheme.
Text documents, emails, social media postings, photos, audio files, video files, and sensor data from IoT devices are all examples of unstructured data. As you can guess, even when the information about a picture or video is semi-structured, the actual data in the file or record is unstructured.
In some cases, unstructured data is called “dark data” because applications often cannot analyze it without appropriate software tools.
Semi-Structured Data
Semi-structured data exists between structured and unstructured data. It has some level of organization but does not conform to the rigidity of structured data.
The data is neither in relational format nor properly organized into rows and columns as in a spreadsheet. However, properties like key-value pairs distinguish it from unstructured data entities.
Semi-structured data is also known as NoSQL data because it does not require a structured query language for data processing and manipulation.
Semi-structured data is frequently expressed as JSON, XML, or key-value pairs.
It’s important to note that Big Data often involves a combination of these data types, referred to as “variety” in the three Vs of Big Data (Volume, Velocity, Variety). The variety of data types poses challenges in storing, processing, and analyzing Big Data, leading to the adoption of specialized data storage capabilities and NoSQL databases capable of handling diverse data structures.
Characteristics Of Big Data Databases
Big Data databases have several characteristics that distinguish them from traditional relational databases. The following characteristics are essential for handling Big Data’s massive volumes, variety, velocity, and complexity.
Scalability
Big Data databases can scale horizontally to handle additional data. Similarly, they handle high-velocity data streams by distributing data across multiple servers or nodes.
Distributed Architecture
These databases have a distributed architecture for faster parallel processing, enhancing overall performance and significantly reducing response time.
