Introduction to Databases: Definition, characteristics, and types of databases (hierarchical, network, relational). DBMS Overview: Definition, advantages, components, and architecture of DBMS (schema, instances, and database languages). Data Models: Overview of different data models (hierarchical, network, relational, object-oriented). Introduction to Relational Databases: Basic concepts of relational databases, tables, rows, columns, and keys. Database Applications: Examples of database applications in business (CRM, ERP, e-commerce).

Entity-Relationship (ER) Model: Entities, attributes, relationships, ER diagrams, and converting ER diagrams to relational schemas. Relational Database Design: Designing relational schemas, primary keys, foreign keys, and constraints. Normalization: Concept of normalization, functional dependencies, normal forms (1NF, 2NF, 3NF, BCNF), and their importance in database design. Designing Relational Databases: Practical steps in designing a relational database, identifying entities, relationships, and attributes.

Introduction to SQL: Overview of SQL, history, and importance in database management. Basic SQL Queries: SELECT statement, filtering data with WHERE clause, sorting data using ORDER BY, and using DISTINCT to eliminate duplicates. Working with Multiple Tables: JOIN operations (INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN) to retrieve data from multiple tables. Data Aggregation: Aggregate functions (COUNT, SUM, AVG, MIN, MAX), GROUP BY and HAVING clauses. Subqueries: Writing subqueries in SQL and understanding their use in complex queries.

SQL Functions: String functions, date functions, and mathematical functions. Views in SQL: Creating and managing views, advantages of using views in database management.

Database Performance Tuning: Basic concepts of performance tuning, query optimization, and database maintenance. Case Study 1: Designing and implementing a database for a small business application (e.g., inventory management). Case Study 2: Analyzing a business dataset using SQL queries to generate insights and reports.
