Database Programming with C# and ADO.NET

Connecting software applications to databases is a fundamental skill for any backend developer. This course provides a clear, text-based path to mastering database communication in C# using ADO.NET, the foundational data access technology for the .NET ecosystem. By completing this course, you will transition from writing isolated applications to building robust, data-driven C# applications that securely retrieve, insert, update, and delete database records. You will gain a deep understanding of connection management, command execution, and modern asynchronous data access patterns. What you'll learn: - Understand foundational database concepts, connection strings, and the ADO.NET architecture. - Establish secure database connections and manage connection lifecycles efficiently. - Execute SQL commands, retrieve data using readers, and handle disconnected data. - Prevent SQL injection vulnerabilities by implementing parameterized queries. - Apply modern C# async/await patterns to perform non-blocking database operations. - Manage database transactions to ensure data integrity and handle rollback scenarios. The course begins with core database terminology and the basics of connection strings before moving step-by-step through command execution, data readers, and transaction management. You will read clear explanations, analyze robust code snippets, and complete written exercises to reinforce your database programming skills. This course is designed for beginner C# developers who want to learn how to connect their applications to relational databases. No prior database programming experience is required, though a basic understanding of C# syntax is recommended. Start reading today to unlock the power of data-driven C# development.
