Data Science Life Cycle | 7 Phases of Data Life Cycle

Data science lifestyle is about using machine learning to analyze data and give predictions to achieve business goals. The entire process involves many steps that you should follow for a better outcome. It may take several months for you to complete. But you can follow the data science life cycle to solve every problem at hand. 


What Is Data Science Life Cycle Project?


In simple terms, data science life stages are some steps that you need to follow while completing any project. Although you may have to follow a different process for developing each project. That means every data science life cycle can be slightly different according to companies’ demands. However, for most of the analysis (data science cycle), you have to follow a general structure and few steps.


Data Analysis Life Cycle Phases

Analyzing surrounding data can help you to predict the future, hypothetically. In order to proper analysis and result presentation, you can follow 7 steps to gain success. Additionally, you will find these steps in each data science case study generally.  Read on to gain knowledge about the path you should follow to complete your data science project.


Understanding Project

First, you need to find out the problem that your client is facing. Understand his business and requirements and what the company wants to achieve. In this case, it’s important to take a consultant from the client to learn about the problems present in the system. Even a simple error in understanding can be crucial for the project. So that you have to analyze every aspect in precision before starting your work.


Data Acquisition

In order to perform your operation, you need data. Now identify the person or way to gather the required data for your particular work. For some data analysis cycles, you need to use online sources to gather your required data.  In that case, you have to gather knowledge from web servers, social media data, data from online repositories.

Not only that you may have to use web scraping or data that could be present in excel. The data acquisition process entails gathering information from all sources, both internal and external, that are relevant to the business challenge. The data acquisition process entails gathering information from all sources, both internal and external. You have to collect all relevant data to solve get an exact result.


Data Preparation

A data cleaning stage, or data wrangling, is the process of combining data sets, cleaning them, and resolving missing values. You need to move forward after gathering data from relevant sources. This stage helps you o a deep understanding of the data you collected. So that you can use them for further evaluation. With help of feature engineering, create new data and extract new features from collected data. In this section, delete unnecessary functions and build the desired structure according to the format. 


Data Modeling

Data modeling is the heart of any data analysis process. In this section, you need to input prepared data for the desired outcome.

In order to acquire results, selecting the appropriate type of model is important. Selecting the proper data model depends on the data type you have received. Use the appropriate machine learning algorithm that suits the selecting model. Tune the hyperparameters of the selected model to get the favorable outcome of your project. 

Make sure to keep a balance between specificity and generalizability to keep the model’s accurate. 


Model Development 

Before we implement the model, we must undertake a thorough evaluation. The application is then deployed in the specified channel and format. When the data development life cycle reaches this level, they are naturally nearing the end of their life cycle. To avoid errors, it is crucial to properly execute each step.

If you use the wrong machine learning algorithm, you will not be able to attain the desired accuracy for data modeling. Obtaining approval for the project will also be tough. If the data has not been properly cleaned, dealing with missing values and noise will be tough. As a result, you will need to do rigorous testing at each stage to ensure that the model is deployed correctly and consistently.



In this step, we create a strategy for tracking and managing the data science project throughout time. Experts monitor this phase to make sure the model is performing as expected. It will assist data scientists in archiving their learnings from data science projects for use in the future. 



In general, this is the final phase of any data science project. In this stage, a machine language is used to retrain the model when new data is added. 




What Makes The Data Cycle Useful?

Here are the factors that make the data cycle useful


  • It assists you in maximizing results by utilizing data obtained from marketing operations.
  • You can use it to assess your competitors.
  • Using this function, you may learn what your website’s visitors enjoy about it.
  • Visually appealing method of displaying collected data


What Is a Data Science Model?

A data model provides structure to data and regulates their relationship with one another. An information model depicts the relationships between different types of information through a diagram. For calculating the results, statistics generally store in a database. Building a data model is an essential skill for any data scientist. 


What Are The Generic Steps In Data Analysis?

You can grow your business or predict the future through analyzing relevant data. Here are the steps you should follow to data analysis


  • Identify your problems.
  • Establish clear measurement priorities. 
  • Obtain data.
  • Analyze the data.
  • Interpret results.
