WHAT IS “BIGDATA”?

Bigdata is nothing but a large volume of data or a massive size of files. It can be in a structured form or may be unstructured. Mostly and widely, Bigdata is used to analyze the data for better business decisions and also to help them in making future business strategies. To understand the Hadoop candidate should have the prerequisites as Java, SQL, and little knowledge of LINUX, 3RI Technologies is offering the Big Data Hadoop Training in Pune with all the above-stated prerequisites. Ideally, there are three significant aspects which make Bigdata so powerful-

Volume

Speed

Variety

Volume:- Earlier Data collection was a tough task for any organization since data can be of a flat file, CSV file, pipe-delimited, spreadsheets form, social media, or maybe core business transactions. Hadoop makes life easy for these organizations that dealt with extensive data.

Speed:- Typically, it shows the rate by which you receive or transfer the data from one node to another. We can understand this by the simple example of Facebook, where we comment, like, and share any post, and it gets reflected in the very next moment, which is nothing but the speed of Bigdata.

Variety:- The significant advantage of Bigdata is that it can handle very many types of data as mentioned in the Volume section, Bigdata can handle structured format, unstructured documents such as text, email, video, audio, or financial transaction data.

WHAT IS HADOOP?

Fundamentally Hadoop is an open-source infrastructure framework that allows store and processes the massive size of data or Bigdata. Since it is based on a cluster system, it works in a Master-Slave Architecture. In Master-Slave Architecture, the extensive data can be stored and processed in parallel. Structured, semi-structured and unstructured of data can be analyzed, Components of Hadoop

HDFS: Hadoop Distributed File System

Yarn

Map Reduce

Hadoop Common

3RI Technologies provide all the topics in detail for Hadoop and Bigdata contents, from scratch as MapReduce, PIG, HIVE, FLUME, SQOOP, etc. in our Hadoop Training in Pune course.

ADVANTAGES FOR ENTERPRISES:

The most critical and valuable takeaway from Hadoop Big data is a business can analyze their past data and make the business strategies for the future:

Better Decision making

Cost-effectiveness

Time-effectiveness

Time to develop new products.

WHAT HADOOP DOES?

It provides you cost-effective storage solution for data.

It provides easy to access a variety of data and analyze it quickly and effectively.

It provides scalability in terms of storage.

It is widely adopted now by different domains like healthcare, e-commerce, retail, BFSI, Supply Chain Management, Telecommunications, etc.

Since it works on multiple unstructured nodes, there will always be a copy of data in case it failed on a particular node.

Hadoop is a faster, cost-effective, and most rapid technology in terms of data storage and data analysis.

ADVANTAGES OVER RDBMS

RDBMS is more suitable for relational data as it works on tables. The main feature of the relational database includes an ability to use tables for data storage while maintaining and enforcing individual data relationships.

Feature RDBMS Hadoop Data Variety Mainly for Structured data. Used for Structured, Semi-Structured and Unstructured data Data Storage Average size data (GBs) Use for large data set (Tbs and Pbs) Querying SQL Language HQL (Hive Query Language) Schema Required on write (static schema) Required on reading (dynamic schema) Speed Reads are fast Both reads and writes are fast Cost License Free Use Case OLTP (Online transaction processing) Analytics (Audio, video, logs, etc.), Data Discovery Data Objects Works on Relational Tables Works on Key/Value Pair Throughput Low High Scalability Vertical Horizontal Hardware Profile High-End Servers Commodity/Utility Hardware Integrity High (ACID) Low

Initially, if you know RDBMS, it is good to learn HDFS. But, sometimes people are coming from configuration management, data analytics, freshers, or from the non-IT background, we teach them Oracle SQL(RDBMS) and then show them HDFS in our Best Hadoop Training in Pune Course.

WHY HADOOP?

Because of its low-cost implementation, Hadoop is attracting the business to adopt it more conveniently. As per a report by Allied Market Research, The market for Hadoop is projected to rise from $1.5 billion in 2012 to an estimated $16.1 billion by 2020. Significantly observed that the DBMS industry has expanded from application and web into healthcare, retails, e-commerce, banking, hospitals, and government, etc. This expansion creates a massive demand for cost-effective platforms, which can be scalable like Hadoop. The key to the success of Hadoop is nothing but the advantages it provides to end-users:

Scalable

Resilience to failure

Cost-effectiveness

Fast

Flexibility

Importance of Big Data Analytics There is no doubt that Big Data analytics is a revolution in the field of Information Technology. Companies have realized its advantages and are enhancing their usage day by day. Since any business is based on users, this field is flourishing in Business to Consumer (B2C) applications. We can divide Big Data analytics into three divisions as:

Prescriptive Analytics
