Series “Enterprise DAL”

Welcome to the fourth installment of our series on building a robust, enterprise-grade Data Access Layer (DAL) in C#. In our previous post, we established a powerful automated auditing system to track entity creation and modification times (CreatedAt/ModifiedAt). Now, we will tackle another critical enterprise requirement: soft-delete.

In our previous posts, we laid the foundation for our enterprise Data Access Layer (DAL). We established our core principles: a database-first philosophy, the use of C# and Linq2Db, and a commitment to automating cross-cutting concerns to enhance security and data integrity. We also structured our project, set up a scaffolding interceptor to enrich our auto-generated entities, and chose ULIDs as our primary keys for their performance benefits.

Welcome back to our series on building a robust, enterprise-grade Data Access Layer (DAL) with C# and Linq2Db. In our previous post, we established the core principles and non-negotiable capabilities our DAL must possess, including automatic multi-tenancy filtering, soft-delete, and auditing. Now, we'll begin laying the foundation for this powerful system by defining the database schema and the initial code structure.

In enterprise software development, the Data Access Layer (DAL) serves as the critical interface between an application's business logic and its underlying data store. Beyond basic CRUD operations, a robust DAL is fundamental for ensuring data integrity, security, and operational consistency. It proactively addresses cross-cutting concerns, preventing inconsistencies, defects, and potential security vulnerabilities that arise when these responsibilities are left to the business logic.
