Understanding the Basic Workflow of Data Analytics
This article will introduce you to the basics of workflow of data analytics, covering essential steps like data collection, cleaning, analysis, and visualization. Whether you’re a beginner or looking to enhance your skills, this guide will provide a clear understanding of the process and its importance.
Basic Idea Of Data Analytics:
Data analytics is the process of examining, cleaning, and interpreting data to uncover patterns, trends, and insights. It helps organizations make informed decisions and solve problems by transforming raw data into valuable information.
Understanding Workflow Of Data Analytics
What is Data Analytics?
- Data analytics refers to the process of examining, cleaning, transforming, and modeling data with the goal of discovering useful information, drawing conclusions, and supporting decision-making.
- It involves techniques and methods from statistics, machine learning, and artificial intelligence (AI) to analyze complex data sets.
- Data analytics is used across various industries to help organizations make data-driven decisions.
What Does Data Analytics Include?
Work Process:
- Data Collection: Gathering relevant and accurate data from different sources.
- Data Cleaning: Removing or correcting erroneous, incomplete, or irrelevant data.
- Data Transformation: Converting data into a usable format for analysis.
- Data Analysis: Applying statistical or machine learning models to extract insights.
- Data Visualization: Presenting the data in graphical formats (charts, graphs, dashboards).
- Reporting & Decision Making: Communicating findings and using data to inform business decisions.
Technicalities:
- Data Types: Qualitative (text, categorical data), Quantitative (numeric data), Time-series, etc.
- Statistical Techniques: Regression analysis, hypothesis testing, correlation, etc.
- Machine Learning Models: Supervised and unsupervised learning, clustering, classification, etc.
- Data Architecture: Knowledge of databases, cloud storage, data lakes, and warehouses.

Workflow of Data Analytics Practices
Data Analytics mainly includes following steps in the workflow:
- Problem Definition
- Data Collection
- Data Cleaning
- Data Exploration/Analysis
- Model Building
- Data Visualization
- Insights and Reporting
- Decision Making
1. Problem Definition:
- Description: Understand the business problem or question you’re trying to answer. This step defines the scope of analysis and what you need to achieve.
- Real-World Example: A retail company wants to understand the reasons for declining sales in a specific region.
2. Data Collection:
- Description: Gather the relevant data from different sources, such as internal databases, APIs, web scraping, or third-party services.
- Real-World Example: Collecting sales data, customer demographics, and competitor performance data.
3. Data Cleaning:
- Description: Process the data to correct or remove errors, such as missing values, duplicates, or inconsistencies.
- Real-World Example: Removing duplicate customer entries or filling in missing age values.
4. Data Exploration/Analysis:
- Description: Analyze the data using statistical methods or visualizations to understand trends, patterns, and outliers.
- Real-World Example: Analyzing sales trends over time to identify whether there is a seasonal pattern or irregular fluctuations.
5. Model Building (Optional):
- Description: If predictive insights are needed, build machine learning models (classification, regression) to forecast future trends or behaviors.
- Real-World Example: Building a predictive model to forecast future sales based on historical data.
6. Data Visualization:
- Description: Present the findings in an easily interpretable format using charts, graphs, or dashboards.
- Real-World Example: Creating a dashboard with graphs showing sales performance across regions.
7. Insights and Reporting:
- Description: Extract actionable insights from the data and report findings to stakeholders in a clear and concise manner.
- Real-World Example: Reporting to the management that sales in a specific region are declining due to customer dissatisfaction with a recent product update.
8. Decision Making:
- Description: Use the insights gathered to support decision-making. This could involve improving strategies, changing policies, or optimizing operations.
- Real-World Example: Suggesting product improvements or pricing strategies to boost sales in the declining region.
