Data Science is the science focused on the study of data. It is responsible for extracting information from large amounts of data. Data Science combines statistics, mathematics, and computing to interpret data. The goal is to make decisions. Learn data science program from Prwatech data science training institutes in Bangalore at advanced level.

This data is obtained through different channels. Mobile phones, social networks, e-commerce or surveys are just some of the sources used. Our tastes, routines or movements generate data of great value for companies that want to know their customers in detail. However, the interpretation of unstructured data does not add value to companies. Hence the need for data scientists on their teams. Thanks to Data Science, companies can anticipate when making decisions.

Where does the term Data Science come from? The term 'Data Science' has been around for the past three decades. But it was not until the 1970s that the term began to be used to define data processing methods. Finally, 2001 was the year that data science was introduced as an independent discipline.

Is Data Science the same as Big Data?

When we talk about Big Data we are referring to large volume data sets. This makes it difficult to store, manage, process and analyze it using conventional technologies and tools.

In short, Big Data is responsible for solving data management and storage problems. This allows you to draw patterns and get a more complete view of customers.

Prwatech is the leading Training institute for data science training in Bangalore Offering Data Science certification courses in bangalore with our Qualified Industry Certified Experts. Our python training institute in bangalore was specially designed for those who are keen to learn the python course from Scratch to Advanced level.

Key concepts in Data Science

There are a series of basic concepts that form data science and that we will briefly explain below.

Data mining

Data Mining is defined as a process used to collect and store useful data.  This requires analyzing data patterns in large batches using one or more software. Thanks to this process, companies can obtain more information about their clients and develop more effective strategies. This helps them make better decisions based on information. To segment the data and evaluate it, Data Mining uses mathematical algorithms.

Deep learning

The goal of Deep Learning is to solve problems through neural networks that mimic brain behavior. These networks of artificial neurons are structured in layers. The first layer is where the information is captured. These data go to the next layer, in charge of performing calculations. And finally, the information collected is projected on the last of the layers. Some of the most used applications in Deep Learning are word processing and image, object or voice recognition.

Machine learning

First of all, it must be emphasized that Machine Learning is not synonymous with artificial intelligence. Rather, it is a concept framed within it. Fundamentally, Machine Learning is responsible for educating technology to correct mistakes on its own. It relies on prediction and classification of data to obtain useful information applicable to different areas.

Artificial intelligence (AI)

Despite big data currently ranking among top business intelligence and data analytics trends, businesses continue to suffer from a lack of data-savvy talent. Research from BARC shows half of respondents reporting a lack of analytical or technical know-how for big data analytics. This is good news for tech beginners, however, whose knowledge and skills are being welcomed by companies who want to reap the benefits of big data.

If you find data science a tempting opportunity, you’ll benefit from this overview of big data basics for beginners. Below, we’ll discuss what the requirements for jobs are and which skills you should master in order to start a successful data science career.

What is Big Data?

Instead of reciting a definition or giving a generic overview, let’s look at big data’s key features through the lens of something that is well known to all of us: recommendation engines. These are tools widely used in e-commerce to aid in customer experience, but that also help gather data about consumers. Web store visitors search for products, view them, add and remove them from their carts, make purchases like, etc. – and every activity is an entry in a database. The entry may look like “Customer X opened Product Y page.” Millions of customers exist, and they perform dozens of activities per visit, which means that a retailer needs impressive storage capacity to log all these actions.

Distributed data storage has become a solution to this problem. According to this principle, data is stored on numerous standard computers rather than on one custom-built powerful machine. This allows companies to achieve high scalability: when the number of records increases, the retailer can just add extra machines.

Each time a visitor starts a new tour on the website, the analytical system tracks all their activities and compares them with previous activities of this particular visitor and those of other visitors. In order to perform this task quickly, the analytical system divides the tasks among numerous machines to enable parallel data processing. The analysis results lay the basis for personalized recommendations.

Summing it up: Big data is data sets that resemble a log of events by nature and require distributed data storage, parallel data processing and special approaches and methods. You can learn more about big data use cases in this primer.

Big Data Technology Stack

You should generally expect to master multiple technologies to become an expert in big data. We’ve selected the most popular frameworks and programming languages for a beginner to get acquainted with. The list is not exhaustive: so, feel free to go beyond it whenever you are ready.

Big data frameworks

Apache Hadoop is a framework for parallel data processing and distributed data storage.

Apache Spark is a parallel data processing framework.

Apache Kafka is a stream processing framework.

Apache Cassandra is a distributed NoSQL database management system.

Big data programming languages

Java

Scala

Python

R (not obligatorily, but good to know)

What are the Programming Paradigms Used in Big Data?

It’s advisable to grasp general programming concepts (such as declarative and imperative), as well as big data-specific paradigms (MapReduce).

Declarative paradigm is the approach to programming that is focused on declaring what the task is and the expected results are, without describing the control flow. This approach is used in database programming. For example, SQL (Structured Query Language) is a declarative language.

Imperative programming is the approach focused on describing the commands that should be executed for the program to change its state. It is used for backend development (for instance, in Java).

For example: Copy a directory from A to B shows a declarative approach, while if it’s enriched with such commands as check if there are existing files with the same name and copy only new ones – it’s an imperative approach.

MapReduce paradigm is the concept of parallel processing of distributed data. It allows for dealing with large data sets by applying map function for data filtering, sorting or parameterization and reduce function for summarizing the interim results.

Jobs in Big Data

Now for the burning question: What kinds of big data jobs exist? The good news: there is quite a choice.

Data analysts closely interact with the end users to identify their needs, analyze and interpret data, build reports and visualize data.

Data scientists assess data sources and establish data collection procedures, apply algorithms and machine-learning techniques to mine data.

Data architects design databases and develop relevant documentation and policies.

Database managers control database performance, troubleshoot the corporate databases and upgrade hardware and software.

Big data engineers design, implement and support big data solutions.

Don’t be misled by the fact that only one of the jobs – a big data engineer – refers to big data directly. With good knowledge of big data, you have more value for any job in data analytics. With the lack of such knowledge, you may have limited opportunities in terms of the tasks or projects assigned.
