What is Data Science?

Today technology has revolutionized every sector and every industry in the world through its power to transform the existing business processes and through its power to change the existing way of doing things. There are many modes of operation and many ways of thinking which technology has done away with completely. The Data Science course discusses these.

One of those modes of operation and one of those ways of thinking is the process of estimating things like costs, budgets, materials required, resources required, and time required, on the basis of guesswork and emotions. Businesses and organizations around the world used to lack both the ability and the mechanisms for estimating these things correctly.

But all this has changed completely with the advent of data science. With the power of data science, businesses and organizations are now able to study the entire history of their past requirements and things such as costs, budgets, materials required, resources required, and time required.

Data science enables the businesses and organizations of the world to carry out a thorough, deep, and careful analysis of all their various requirements such as costs, budgets, materials required, resources required, and time required. The data science course teaches how to do this.

It also enables the businesses and organizations of the world to carry out a thorough, deep, and careful analysis of the various material elements of their functioning and operations. These consist of past customer behaviour, past resource usage, past pileups of costs, past delays in deliveries, and many other things.

Data science is the science of extracting patterns from data. In order to extract patterns from data, one has to first detect and identify them. In order to detect and identify patterns in data, one must first actually possess data. One can learn how to do this by taking a data science course.

So one will find that the lion’s share of a data scientist’s work is in collecting data. He does it by recording and collecting data in massive data sets which he then cleans and manipulates so that it reaches a usable state.

This task of cleaning and manipulating the data is only the initial step in the vast process which comprises data science but it is a very difficult and extensive task and takes up a lot of the data scientist’s time. This task is expounded upon in a data science course.

It also involves a lot of skill and experience. The more experienced a data scientist will be the faster he will be able to analyze and survey a data set and find out the flaws and shortcomings in it. Then he will be able to rectify those shortcomings in a short amount of time because of his experience which will guide him in the right direction in making changes to the data set.

What are the skills required to become a data scientist?

1. Statistics -

Statistics is the field of studying data and carrying out a deep, thorough, and careful analysis of it. It uses several advanced and sophisticated mathematical techniques to accomplish this. It also involves several visual elements such as charts, bar graphs, pie charts, histograms, tables, etc.

Statistics gives data scientists the tools to collect, organize, and analyze data in a very scientific and precise way. With their deep, thorough, and careful analysis of data, they are able to identify several key pieces of information from the data known as data points. This analysis is mentioned in the data science certification.

They are also able to present the data in a visually comprehensible and visually attractive manner. The tools and techniques that statistics provides to data scientists enable them to present information in an organized and easily understandable manner so that even laypersons who don’t necessarily have a technical background are able to understand and comprehend it.

From the above points, one can easily understand that statistics is one of the most important skills that a data scientist should possess. In fact, it is one of the most valuable tools in the toolbelt of an experienced and seasoned data scientist since it enables the data scientist to understand, manipulate, and present data in a variety of ways. These ways are discussed in a data science certification.

2. Knowledge of one programming language such as Python or R -

The data scientist must possess knowledge of at least one programming language such as Python or R. Python Language is the best choice for Data Scientists to know how to write code in any programming language suitable for data science.

Python and R are two eminently suitable programming languages for use in data science. There are a number of benefits associated with using either of the two programming languages. Python for instance has a large number of libraries which the Python programmer community has built especially for use in data science.

These large number of libraries have been written with the specific purpose of solving problems which are commonly encountered by data scientists. Any data scientist who uses Python will find that he will not have to reinvent the wheel or write new and fresh code for problems which are commonly encountered in the field of data science.

Python also offers the added advantage that it has a very simple and easy-to-understand syntax that resembles natural human languages. This makes it very easy for data scientists to parse Python code and even to learn the Python programming language as beginners to programming and beginners to Python.

If we consider the R programming language, it is a language which has been designed specifically for use in data science. It has several powerful and convenient features which enable data scientists to analyze, manipulate, and present data in very efficient and effective ways.

3. Data extraction, transformation, and loading -

The data scientist should know how to carry out the processes of data extraction, data transformation, and data loading. A big part of a data scientist’s work revolves around doing these things efficiently and effectively. The process of data extraction is especially important for a data scientist because it is the very first step in acquiring, manipulating, and formatting a data set.

4. Data wrangling and data exploration -

Data wrangling is the process of selecting, collecting, manipulating, and formatting data in such a way that it provides the answer to a question. Before starting the process of data wrangling, the data scientist has to select a particular question which he wants to answer.

Then he has to shape his data collection, data searching, and data sorting methods according to the particular question which he has selected. For instance, if the data scientist wants to answer a question related to traffic jams in a particular part of the city, he will have to go on the ground and collect data from the roads of that particular city. He will also have to decide which times of the day are most appropriate for analysis.

What is Data Analytics?

Data analytics is the process of detecting and identifying emerging trends in the data. It is used by data analysts to understand and comprehend the emerging trends in data. On a practical level, this can translate to identifying emerging trends in the purchasing patterns and other miscellaneous behaviour of a business or organization’s customers.

It can also translate to an automobile manufacturer using data analysts to calculate how many parts of the automobiles it manufactures turn out to be defective. With the help of data analysts, the automobile manufacturer will be able to detect and identify the emerging trend in the rate of defects in its manufactured automobiles.

What are the Skills Required to Become a Data Analyst?

1. Big Data Processing Frameworks -

1. Hadoop
2. Apache Spark
3. Apache Storm
4. Samza
5. Flink

2. Data visualization -

A data analyst should be extremely well-versed with the art of data visualization. He should be able to produce complex and compelling visual presentations of the data that he has analyzed and studied. With the help of these complex and compelling presentations of data, he should be able to communicate all of his findings and the results of his studies to the management staff of the company he is working in. Data visualization is taught in a data science certification.

Data Science vs. Data Analytics -

The difference between data science and data analytics is very subtle because the two fields are closely related to each other. Data science is a term which encompasses many different areas of study and activity whereas data analytics is a much more specific and concentrated field.

Data science is mainly concerned with generating questions about the data sets that the data scientist possesses that the business or organization may not have considered. It focuses on uncovering more aspects and facets of data. Data analytics on the other hand mainly involves answering the questions which are generated by data science.

What is Machine Learning?

We have all seen or heard about movies which feature talking robots and self-operating spaceships. If these things are ever to become a reality we as a human civilization will need to advance a lot in the fields of artificial intelligence and machine learning. This advancement will come from getting a data science certification.

Machine learning as a field deals with teaching machines how to make decisions on their own without any outside or external intervention. Traditionally, machines were run with the help of computer programs which consisted of a set of fixed instructions.

But in the field of machine learning the programs are written in such a way that they can modify themselves with the help of advanced and sophisticated computer science algorithms and neural networks. These enable the machines to learn new things from their environment and make decisions independently based on the information that they acquire and synthesize.

Data Science vs. Machine Learning -

Data science is a broad term which encompasses many different disciplines and fields of activity. It includes processes like data wrangling, data transformation, data loading, data processing, data warehousing, and many other related processes.

Machine learning on the other hand is a subset of data science which is only concerned with teaching machines how to learn new information and make decisions on the basis of that information. It revolves around making data evolve whereas data science revolves more around studying the nature of data as it is.
