What is Big Data?

Big Data is a very broad term referring to very large, complex and diverse data sets that are extremely resource-intensive, making traditional data management tools unable to effectively process, analyze or store them. The key is that this data is generated quickly and in large quantities from various sources, and their analysis provides valuable information and conclusions that can support business, scientific or technological decisions.

What are the key characteristics of Big Data?

Big Data is often defined using the “3V” approach, although as technology has evolved, additional characteristics have emerged. The basic characteristics that define the 3V approach include:

Volume: The amount of data generated and collected is enormous. This data can come from a variety of sources, such as social media, commercial transactions, IoT (Internet of Things) sensors, cameras, geolocation data, and medical data. Traditional database systems cannot effectively manage this amount of data.

Velocity: Big Data is characterized by rapid generation and processing speed. Data is often collected in real time or near real time. Examples include social media streams, financial transaction data, and sensors in smart devices.

Variety: Data in Big Data can take many forms. It can be structured data (e.g., database tables), semi-structured data (e.g., emails, logs), and unstructured data (e.g., videos, images, text documents). Big Data analytics requires tools to work with a variety of data types.

With the development of Big Data, additional characteristics have emerged:

Veracity: Big Data can be incomplete, imprecise, or contain errors, which can affect the quality of analyses. It is important to consider how reliable and accurate the data is before making decisions.

Value: Data collection alone is not enough—the real value of Big Data is its analysis, which provides valuable information and allows for more informed decision-making. Without analysis and drawing conclusions from the data, its value is limited.

Variability: Data can change over time, and its patterns and structure can be heterogeneous, which further complicates its analysis.

The above-mentioned characteristics of Big Data are used to process data obtained from a variety of sources. The most common include:

• Social media: data from platforms such as Facebook, X, Instagram, or TikTok.
• Internet of Things (IoT): data generated by smart devices, sensors, cameras, thermostats.
• Commercial transactions: data from cash registers, ATMs, online transactions.
• Mobile and location data: data from mobile applications, GPS, geolocation.
• Medical data: electronic patient records, data from health monitoring devices.
• Financial data: information about transactions, stock exchanges, payments.

Technologies supporting Big Data analysis

To effectively manage and analyze such large data sets, dedicated technologies designed specifically for this purpose are necessary. There are many solutions on the market that allow you to effectively use the benefits of Big Data. The most popular technologies used in Big Data include:
