C# and ADO.NET

Course Description

This SkillDynamo course develops practical, role-relevant capability in building database-connected C# applications with ADO.NET connections, commands, parameters, readers, datasets, transactions, stored procedures, security, performance, and layered design. The learning path progresses from essential concepts and planning to implementation, validation, troubleshooting, and operational use.

Learners work through realistic scenarios, guided demonstrations, applied exercises, and evidence-based reviews. Every topic is connected to workplace responsibilities, common risks, quality controls, and measurable outcomes.

The course helps professionals make informed decisions, identify failure points, communicate results, and create an actionable improvement plan for future projects.

What You Will Learn

• Design a layered C# data application with configuration, connection factories, repositories, services, models, and dependency boundaries
• Configure providers, connection strings, pooling, opening, closing, disposal, errors, logging, and environment-specific settings
• Execute parameterized queries and stored procedures with commands, readers, scalars, inserts, updates, deletes, and output parameters
• Map database results safely, handle nulls and types, validate inputs, manage errors, and avoid SQL injection
• Use DataAdapters, DataSets, DataTables, relations, constraints, disconnected updates, transactions, isolation, and optimistic concurrency
• Implement batching, bulk operations, stored logic, rollback, retries, idempotency, and data-consistency controls
• Apply identity, permissions, encryption, secrets, auditing, secure transport, and least-privilege database access
• Test data access, tune queries and pooling, monitor failures, deploy configuration, document operations, and support improvements
