Big Data Analytics

What is Big Data Analytics?

- Big Data Analytics is the process of identifying trends, patterns, and correlations in vast amounts of raw data in order to make data-informed decisions.

Big Data Analytics

WHAT IS BIG DATA?

It is data that contains greater variety, arriving in increasing volumes and with more velocity. It is a combination of structured, semi-structured, and unstructured data.

Structured Data

It is data that has a standardized format for efficient access by software and humans alike.

Semi-Structured Data

It is data that is not captured or formatted in conventional ways.

Unstructured Data

It is data that has no predetermined data model or structure.

Characteristics of Big Data

Volume

- Volume describes the vast amount big data contains.

Big Data typically involves massive datasets that exceed the capacity of traditional databases. Handling and processing such large volumes of data require specialized tools and technologies to extract meaningful insights.

Veracity

- Refers to the assurance of the quality or credibility of the collected data.

Ensuring that the data collected is accurate and trustworthy is crucial for making informed decisions. Poor data quality can lead to incorrect analyses and unreliable results, affecting the overall effectiveness of Big Data initiatives.

Value

- Represents the importance and usefulness of the data in achieving business goals.

Big Data analytics aims to extract valuable insights that contribute to strategic decision-making, innovation, and overall business success. The value of data is determined by its relevance and impact on achieving desired outcomes.

Variety

- Variety describes the diversity of data types that makes big data.

Big Data sources come in various forms, such as text, images, videos, social media posts, and more. Managing the variety of data types is essential for a comprehensive analysis that can reveal valuable patterns and correlations.

Velocity

- Refers to the speed at which data is generated, collected, and processed.

With the increasing pace of data generation in real-time or near-real-time, organizations must handle and analyze data swiftly to derive meaningful insights and make informed decisions.

Types of Big Data Analytics

Descriptive Analytics

Descriptive analytics refers to the interpretation, summarization and generalization of data.

Predictive Analytics

Predictive analytics looks at past and present data to make predictions.

Prescriptive Analytics

Prescriptive analytics provides a solution to a problem.

Diagnostic Analytics

Diagnostics analytics helps companies understand why a problem occurred.

Tools in Big Data Analytics

Hadoop is an open source framework based on Java that manages the storage and processing of large amounts of data for applications.

Apache Pig is a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs.

Apache HBase is an open-source, NoSQL, distributed big data store. It enables random, strictly consistent, real-time access to petabytes of data.

Apache Spark is an open-source, distributed processing system used for big data workloads. It utilizes in-memory caching, and optimized query execution for fast analytic queries against data of any size.

Talend is a comprehensive collection of services and software solutions for managing data from multiple sources. Talend's data integration tools make it easy for businesses to quickly combine data from various sources, such as databases, flat files, online services and web API Management.

Splunk is used for monitoring and searching through big data. It indexes and correlates information in a container that makes it searchable, and makes it possible to generate alerts, reports and visualizations.

Apache Hive is a distributed, fault-tolerant data warehouse system that enables analytics at a massive scale. A data warehouse provides a central store of information that can easily be analyzed to make informed, data driven decisions. Hive allows users to read, write, and manage petabytes of data using SQL.

Kafka is primarily used to build real-time streaming data pipelines and applications that adapt to the data streams. It combines messaging, storage, and stream processing to allow storage and analysis of both historical and real-time data.

Importance of Big Data Analytics

Big Data Analytics allows businesses to use their data to uncover areas for improvement and optimization. Increasing efficiency leads to more intelligent operations, bigger earnings, and satisfied consumers across all business segments.
