Definition

Big data

Big Data refers to the massive volumes of data that are generated, collected, and stored through various sources, such as social media, sensors, devices, and transactions. Big Data is characterized by its volume, speed and variety, which makes it difficult to process and analyze with traditional data processing methods.

Data Analytics

Data analysis, on the other hand, is the process of examining, interpreting, and deriving meaningful insights from data. It involves various techniques, tools, and methods for exploring, analyzing, and visualizing data in order to uncover patterns, trends, correlations, and insights that can inform decision-making and drive business outcomes.

Approach

Big Data is mainly focused on the handling, storage and processing of complex and large-scale data sets. It involves technologies such as distributed databases, data lakes, and data warehouses, as well as tools such as Hadoop and Spark for distributed data processing and analysis.

Data analytics, on the other hand, focuses on extracting insights from data to gain insights, identify patterns, and make informed decisions. It involves techniques such as descriptive analytics (summarizing and visualizing data), diagnostic analytics (exploring causes and relationships in data), predictive analytics (forecasting future outcomes), and prescriptive analytics (providing recommendations and optimizing decisions).

Scope

Big Data deals with the large amount of data that is generated from various sources and requires specialized infrastructure and tools for its storage, processing and analysis. It is commonly used in applications such as customer analytics, fraud detection, personalized marketing, and scientific research.

Data analytics, on the other hand, can be applied to both large and small data sets. It can be used in various sectors and fields, such as business, healthcare, finance, sports, etc., to obtain information, drive decision-making and achieve strategic objectives.

Purpose

The purpose of big data is to capture, store and process large amounts of data to identify patterns, trends and insights that can be used for various purposes, such as improving operational efficiency, improving customer experience and driving innovation.

Data analytics, on the other hand, focuses on the use of analytical techniques to extract insights from data for decision making, problem solving and strategic planning. It aims to uncover hidden patterns, relationships, and insights that can drive actionable outcomes and create value.
