Most .NET applications interact with databases, either SQL or NoSQL. Each option has technical advantages that must be evaluated according to the context. Data access mechanisms must be chosen and implemented taking into account performance, scalability, and consistency issues.
This training course allows participants to compare different data access strategies and implement robust transactions using the Unit of Work pattern. Through the use of technologies such as EntityFramework Core, Dapper, and ADO.NET, participants will learn how to structure an effective persistence layer, optimize queries, and monitor execution performance in a .NET environment.

Course architecture
The training is structured around various key stages aimed at strengthening data access and transaction control. Each section combines fundamental concepts with targeted practical application, in conjunction with the flagship tools of the .NET ecosystem.
Introduction
This first stage presents the conceptual basics related to database types, non-blocking input/output, transactions, and object-relational mapping.
- The different types of databases (SQL, NoSQL).
- Non-blocking execution of I/O operations.
- The role of a connection pool.
- Transactions and ACID principles.
- Full-text searches.
- Object/database mapping.
Using EntityFramework Core
Here we explore how the repository pattern works, entity definition, relationship mapping, and implementation of the Unit of Work pattern via DbContext.
- Introduction to the repository pattern.
- Domain entities: strong entities and weak entities.
- Mapping entities and their relationships.
- Implementing the Unit of Work pattern with DbContext.
- The different states of an entity.
- Querying with LINQ.
- Migrations.
Practical application: setting up a persistence layer with EntityFramework Core and transaction management.
Mini-ORMs
The limitations of the pattern repository.
Manipulating contextual data with tuples and records.
Implementing the Unit of Work pattern with ADO.
Querying a relational database with Dapper.
Practical application: creating a data-driven application with Dapper and implementing transactions.
Profiling to measure data access performance
You will learn how to measure the performance of data access operations by activating a profiling tool, defining relevant metrics, and automating the collection of measurements.
- Activating a profiler in an application.
- Choosing metrics.
- Archiving information.
- Alerts.
Practical application: profiling data access operations and exporting measurements to Prometheus.
