Data Science Course Syllabus (Big Data and Analytics Focus)

Module 1: Introduction to Data Science and Big Data

What is Data Science?

Data science is the interdisciplinary field that uses scientific methods, algorithms, and systems to extract knowledge and insights from structured and unstructured data. It blends computer science, mathematics, statistics, and business knowledge to analyze massive datasets and derive meaningful conclusions. In today’s digital age, data science powers decision-making across industries, from healthcare to e-commerce.

Big Data Characteristics: Volume, Velocity, Variety

Big data refers to datasets so large and complex that traditional data-processing software can’t handle them efficiently. It is defined by three primary characteristics, known as the 3Vs:

  • Volume: The sheer quantity of data generated every second — think social media posts, online transactions, sensor data, etc.

  • Velocity: The speed at which new data is generated and needs to be processed — for example, streaming data from IoT devices.

  • Variety: The different forms of data — structured (tables), semi-structured (XML, JSON), and unstructured (text, images, videos).

Data Science Lifecycle

The data science lifecycle outlines the key phases of a typical data science project:

  1. Problem Definition – Understand the business problem and objectives.

  2. Data Collection – Gather data from various sources.

  3. Data Cleaning and Preprocessing – Fix or remove incorrect, incomplete, or irrelevant data.

  4. Exploratory Data Analysis (EDA) – Understand patterns, detect outliers, and test hypotheses.

  5. Modeling – Build predictive or descriptive models using machine learning.

  6. Evaluation – Assess model performance using appropriate metrics.

  7. Deployment and Monitoring – Integrate the model into production and continuously monitor its performance.

Use Cases of Big Data in Various Industries

Big data analytics has transformed industries:

  • Retail: Personalized recommendations and inventory management.

  • Healthcare: Predicting patient readmissions and optimizing treatment plans.

  • Finance: Fraud detection and credit scoring.

  • Manufacturing: Predictive maintenance of machinery.

  • Social media: Sentiment analysis and ad targeting.

Module 2: Python Programming Essentials

Python is the language of choice in data science due to its simplicity and rich ecosystem of libraries.

Python Fundamentals

Students will learn the basics of Python, including syntax, variables, data types (integers, strings, floats), conditional statements (if, else, elif), loops (for, while), and error handling.

Data Structures: Lists, Tuples, Dictionaries

  • Lists: Ordered, mutable collections (e.g., [1, 2, 3]).

  • Tuples: Ordered, immutable collections (e.g., (1, 2, 3)).

  • Dictionaries: Unordered collections of key-value pairs (e.g., {'name': 'Alice', 'age': 25}).

These data structures are crucial for organizing and manipulating data efficiently.

Functions and Modules

Functions let you group code into reusable blocks, while modules allow you to organize functions and classes into separate files or libraries, making your code cleaner and more maintainable.

File Handling

Learn to read from and write to files — for example, working with .txt, .csv, or .json files to process data inputs and outputs.

Module 3: Data Acquisition and Processing

Data scientists work with data from multiple sources and formats.

Import/Export Data Using Python

You’ll gain hands-on skills in:

  • Importing data from local files or web sources.

  • JSON (JavaScript Object Notation)

  • SQL and NoSQL databases (relational and non-relational)

Data Cleaning and Preprocessing

Prepare raw data for analysis by:

  • Handling missing or duplicate data.

  • Correcting data types.

  • Normalizing and standardizing data for machine learning.
