Data Science is the process of extracting meaning from data. It can be broken down into two main tasks: cleaning and transforming data and building models.
In this blog post, we will discuss what is data science and what you have to know about data science.

What is data science?
Data science is the process of applying mathematical algorithms and modeling techniques to data sets in order to extract knowledge.
The goal is to make predictions about how the data will behave in the future and to improve the quality of the data sets.
There are a number of different types of data science, including predictive modeling, data analysis, data visualization, and data science for big data.
The most common type of data science is predictive modeling, which is used to make predictions about future behavior.
Predictive modeling can be used to predict the behavior of individual customers, customers in a given market, or the overall market.
However, we will know different types of data science in this blog post bellow. Now let’s see the lifecycle of data science.
Lifecycle of data science
Data science projects can have a long and varied lifecycle. This Lifecycle of a Data Science Project is a high-level overview of the main stages of a data science project.
There are 6 distinct stages of data science with each of its own tasks. Let’s understand them in details.
1. Discovery of data
Data discovery is very important to understand the various specifications, requirements, priorities and required budget. It is must to ask the right questions.
You should have the required resources present in terms of people, technology, time and data in order to support the project.
2. Preparation of data
In this stage, you need analytical sandbox to perform analytics for the entire duration of the project. It is important to explore, preprocess and condition data prior to modeling.
3. Model planning of data
In this phase, you will determine the methods with techniques to draw the relationships between variables which will set the base for the algorithms by which you will implement in the next phase.
Some common tools for model planning is R, SQL analysis services, SASS/ACCESS
4. Model building
In model building phase, you will develop datasets for training and testing purposes as well as you need to consider whether your existing tools will suffice for running the models.
If it needs a more robust environment like fast and parallel processing then consider it. You have to analyze various learning techniques such as classification, association and clustering to build the model in this stage.
In analyzing phase, you will deliver final reports. Sometimes a pilot project should also implemented here which will provide you a clear picture of the performance before full deployment.
In this final stage, main task is data reporting, data visualizing, business intelligence and decision making.
Analysts have to prepare the analyses in easily readable forms such as charts, graphs, and reports in this stage.
What is a data scientist?
A data scientist is a professional who specializes in extracting meaning from data through the use of mathematics, statistics, and other quantitative methods.
They are responsible for transforming raw data into insights that can be used to improve business processes or create new products.
A data scientist’s job is never complete – they are constantly learning and evolving to keep up with the latest advancements in data analytics.
Prerequisite for data scientist
There’s a lot of thing a data scientist have to know. Some prerequisite for a data scientist is given bellow.
- Machin learning
- Database knowledge
- Artificial intelligence
- Natural language processing
- Big data etc.
In order to become a data scientist, you need to have a strong foundation in mathematics and computer science. This is because data science is all about understanding how data works and how to use that understanding to solve problems.
For example, you need to be able to understand how to collect data, how to analyze it, and how to use that analysis to make decisions. You also need to be familiar with algorithms and data structures, as well as programming languages.
If you want to become a data scientist, you should also take courses in machine learning, natural language processing, and big data. In addition, you should read articles and books about data science.
Data science in business
Data science is a field of study that uses data to improve business decisions. It can be used to improve customer engagement, optimize marketing campaigns, and improve product design.
Data science can also be used to improve decision making by identifying patterns and trends in data.
Data science can be used to improve customer engagement by understanding customers’ needs and wants. This information can then be used to create customized experiences for customers.
Data science can also be used to improve marketing campaigns by identifying which areas of a campaign are most successful. This information can then be used to improve future campaigns.
Data science can also be used to improve product design by analyzing data.
Data science application
There are a huge number of application of data science in this modern era. A short list of this application is given here.
- Image recognition
- Health care
- Fraud detection
- Recommended system
- Voice recognition
- Search on internet
- Route planning of airlines
- Augmented reality etc.
Why data science is important?
Data science is an important field because it helps us understand how the world works.
It helps us understand how to predict what will happen in the future, and it can also help us make decisions about what to do.
