About your data science tutor
I am Ramya G, a passionate Data Science & Artificial Intelligence Tutor with over 2+ years of experience mentoring students, graduates, and working professionals through practical, hands-on learning. My goal is to simplify complex concepts and help learners confidently solve real-world business problems using a project-based approach. I specialize in Data Science, Python, Advanced Excel, Power BI, Tableau, Machine Learning, Artificial Intelligence, NumPy, Pandas, Scikit-learn, and PyTorch. My training covers data preprocessing, exploratory data analysis (EDA), data visualization, feature engineering, model building, and AI fundamentals, combining theory with practical implementation. My sessions include real-time projects in sales, finance, healthcare, HR analytics, customer segmentation, and predictive analytics. Students work with real datasets, build dashboards, develop machine learning models, and create portfolio-ready projects while learning industry best practices. I also teach Machine Learning evaluation metrics, including Accuracy, Precision, Recall, F1-Score, Confusion Matrix, ROC-AUC, MAE, MSE, RMSE, R² Score, Cross Validation, and Hyperparameter Tuning, helping students build accurate and reliable AI models. Beyond technical skills, I provide coding guidance, interview preparation, resume building, capstone projects, and career support. Whether you're a beginner, student, or working professional, I offer a structured roadmap to build practical, job-ready skills for a successful career in Data Science and Artificial Intelligence.

Data Science concepts taught by Ramya
The tutor guided the student through SQL database operations, focusing on using the `ALTER TABLE` command to add new columns to existing tables. They also discussed the importance of documenting these changes through screenshots and the overall process of database modification within the context of an assignment. The student was reminded to schedule future lessons.
SQL Data Types: `VARCHAR`
Modifying Database Tables: Adding Columns
DDL Statements in SQL
Database Operations: `USE` Command
The Tutor and Student focused on SQL database assignments, specifically reviewing and correcting submissions for Unit 3 and introducing the concepts for Unit 4. They practiced generating and executing SQL DDL statements for table alterations and discussed the requirements for documenting these changes. The session was cut short due to time constraints, with plans to continue the Unit 4 work in a future meeting.
Database Schema and Structure
Data Definition Language (DDL)
Querying and Retrieving Data (DML)
SQL Server Management Studio (SSMS)
Using AI for Code Generation (ChatGPT)
The Student and Tutor focused on database creation using DDL statements, practicing with AI tools to generate SQL code and executing it in SQL Server Management Studio. They reviewed error handling and the importance of verifying AI-generated scripts, with the Student tasked to complete and document the creation of database tables.

AI Assistants for Database Schema Generation
Executing SQL Commands in SQL Server Management Studio (SSMS)
The tutor guided the student through the process of creating a database and designing tables in SQL Server Management Studio. They practiced defining table structures, setting primary keys, and establishing foreign key relationships between tables based on a provided diagram. The student also learned to troubleshoot permission errors during database creation.
Database Creation in SQL Server
Primary Keys and Unique Identification
Varchar Data Type
Relationships and Foreign Keys
SQL Query Execution
The Tutor guided the Student through the installation and connection process for Microsoft SQL Server Management Studio (SSMS) to physically build databases. They discussed the concepts of primary and foreign keys and initiated the creation of a 'movies' database with related tables like 'director', 'star', and 'journal'. The next session will involve a visual demonstration of database and table creation.
