Learning tools that you should take advantage of
Online data science learners must not only understand what they are doing, but also practice using data science on a variety of different problems.
You should also read the following two books in addition to the courses on this page:
- One of the most widely recommended books for beginners in data science, Introduction to Statistical Learning is freely available. Provides an introduction to the fundamentals of machine learning and the underlying principles in action
- An in-depth look at how predictive modeling can be applied to real-world data sets, with a wealth of practical advice along the way.
It is much more useful to study with the help of these two textbooks than to take courses on their own. If you are able to understand most of what was said in the first book, you will be a better data scientist than most budding scientists.
A great learning experience would be working through these two books in R and then converting them into Python, as both the exercises and examples use R.
Where can I learn about big data technology?
The term “big data” refers to a collection of data that is massive in scope and is growing at an exponential rate. There are simply too many data points to store, investigate, and transform with existing management methods.
It is true that big data technologies are the tools and techniques used to investigate and transform massive amounts of digital data. This includes extracting, storing, sharing and visualizing data.
Radical technologies such as machine learning, deep learning, and artificial intelligence (AI/IoT) are widely associated with widespread rage in technology.
You can learn more about big data by watching this video (Introduction)
Using big data, it is possible to classify technologies.
1. It is all about operational big data:
Big data techniques are used to analyze data from a variety of sources, such as daily online transactions, social media, or any other type of data produced by a single company. Analytical big data technologies use it as raw data. Seasourcedata.com big data
Personal information of MNC executives, online trading and buying from Amazon and Flipkart, as well as online ticket reservations for movies, planes and trains are examples of operational big data technologies.
2. Big Data Techniques for Analysis:
Compared with operational big data, this indicates a more advanced adaptation of big data technologies. Data analysis that is critical to making business decisions is included in this section. Time series analysis and medical and health records are among the examples that are covered in this field.
Big data technologies for the year 2020 | Seasourcedata.com big data
It’s time for us to take a closer look at some of the latest technologies that have recently had an impact on business and technology. Seasourcedata.com big data
1. Artificial intelligence
As a broad field of computer science, artificial intelligence covers the development of intelligent machines that can perform a wide range of tasks that would normally require human intelligence. (You can learn more about how AI simulates the human brain here.)
Artificial intelligence (AI) is advancing rapidly, taking in a wide range of approaches, such as reinforcement machine learning and deep learning, to dramatically transform almost every technology industry.
The greatest strength of AI is its ability to think critically and make decisions that have a reasonable chance of achieving the desired outcome. Many industries are seeing the benefits of continuous improvement of AI. To give just a few examples, AI can be used in medical treatment to treat and heal patients and perform surgery.
2. NoSQL database
To design modern applications, NoSQL integrates a wide range of discrete database technologies. The illustration shows a non-SQL database, or a non-relational database, that provides a means of storing and retrieving data. Web-based real-time applications and big data analytics take advantage of these technologies.
To understand real-time big data analytics: (Must read to understand the Internet of Things (IoT))
It stores unstructured data and provides faster performance, providing flexibility while handling a wide range of data types at scale. MongoDB, Redis, and Cassandra are just a few examples.
In addition to improving horizontal scaling for a wide range of devices, it also gives users more power and control over potential opportunities. It speeds up NoSQL computations by using data structures that are not included by default in relational databases. Terabytes of user data are stored every day by companies like Facebook, Google, and Twitter.
3. R programming | Seasourcedata.com big data
R is a freely available open source programming language and project. Statistical computing, visualization, and unified development environments such as Eclipse and Visual Studio helper communications use this free software.
He claims that it has become the most widely spoken language on the planet, according to an expert. In addition, it is frequently used in the design of statistical software and in the analysis of large amounts of data, particularly in data mining. Seasourcedata.com big data
4. Data Lakes
Data lakes refer to a central repository for storing all kinds of data, whether structured or unstructured, of any size.
You don’t necessarily need to turn your data into structured information and perform many types of analytics on it, such as dashboards and visualizations, real-time analytics, or machine learning to improve business interactions during the data collection process. (See Blog: 5 Common Types of Business Analytics Data Visualization)
There are many advantages to using data lakes in an enterprise, such as the ability to perform machine learning across log files from social media and clickstreams, as well as IoT devices frozen in data lakes.
Customers are brought and engaged, productivity is maintained, devices are actively maintained, and informed decisions are made to help businesses grow faster.
5. Predictive analytics
It is a subset of big data analytics that aims to predict future behavior based on past data. Prediction of future events is made possible through the use of machine learning, data mining, statistical modeling, and other mathematical models.
Predictive analytics is a science that generates accurate inferences for the future. With predictive analytics tools and models, any company can use data from the past and present to identify potential trends and behaviors in the future. To learn more about predictive modeling in machine learning, you should read this blog post.
Such as checking correlations between trend parameters. Models such as this one are used to evaluate the promises and risks associated with a given set of possibilities.
6. Apache Spark
Apache Spark is the fastest and most popular generator for big data conversion due to its built-in streaming, SQL, machine learning, and graph processing features. This tool supports Python, R, Scala, and Java.
It was already covered in a previous post about Apache web server architecture.
Spark was the driving force behind the introduction of Hadoop, as the primary goal of data processing is speed. It reduces the time it takes to run the program after questioning the user. Spark is mainly used in Hadoop to store and manipulate data. More than a hundred times more on MapReduce.
7. Descriptive analyses
In order to help companies achieve their desired results, descriptive analytics provides them with tips. Therefore, if a company receives notice that a product feature is expected to diminish. Descriptive analytics can help investigate various factors in response to market changes and predict the most favorable outcome.
However, rather than focusing on collecting and gathering only data, this approach focuses on gaining insights that can be used to improve customer satisfaction and business profitability while also enhancing operational efficiency.
8. In-memory database
It is an in-memory database management system (IMDBMS) that manages and stores the in-memory database (IMDB). Disk drives used to be the primary storage medium for traditional databases.
The machines modifying the blocks to which data is written and read influence the design of traditional disk databases.
Alternatively, when one part of the database references another, it feels the need to read a different number of blocks on disk. By using direct pointers to monitor threaded connections between databases, this is not a concern for the in-memory database.
Since disk access is no longer necessary, in-memory databases are designed to keep processing time to a minimum. As a result, a process or server failure may result in complete data loss, since all information and its entire control are stored in main memory.
9. Blockchain
Due to its unique feature of permanently preserving data once it is written, Blockchain is the database technology intended for the Bitcoin digital currency.
This highly secure ecosystem is one of the best places to use big data in industries such as banking and financial services, healthcare, and retail.
Although the blockchain technology is still in the early stages of development. Merchants from various organizations including AWS, IBM, Microsoft. As well as startups have tried multiple experiments to offer possible solutions in building the blockchain technology. (See blog post: Do Blockchain and AI Have an Ideal Paradigm?).
10. Hadoop Ecosystem | Seasourcedata.com big data
The Hadoop ecosystem consists of a platform that helps solve big data challenges. Data ingestion, storage, analysis and maintenance are just some of the functions it provides.
In the Hadoop ecosystem, most of the services exist to support various components such as HDFS (YARN), MapReduce (Common), or HDFS (HDFS).
A wide range of commercial and open source solutions and tools are included in the Hadoop ecosystem. Spark, Hive, Pig, Sqoop, and Oozie are just a few of the well-known open source examples.

The most important use of big data is future planning. Which is achieved by predicting how people will live and what they will buy in the future. However, it is not a magic mirror. The predictive power of long data sets (also known as “long data”). Which cover decades or centuries of data, is much greater than the predictive power of short data sets. In (which cover only one year). Even the most reliable data has its limits when it comes to predicting cultural changes such as the rise of smartphones. Seasourcedata.com big data
