Example Code for Database Connectivity and Three-Layer Model Structure

Welcome! This repository contains example code to help you understand database connectivity and the three-layer model structure in software development.

What is this repository for?

This code is designed to demonstrate key concepts related to:

  • Database Connectivity: How to connect your application to a database (Microsoft SQL Server).
  • Three-Layer Architecture: The separation of your application into three layers:
    1. Data Access Layer (DAL): Handles interactions with the database.
    2. Business Logic Layer (BLL): Contains the core logic of the application.
    3. Presentation Layer (PL): Manages user interfaces and interaction.

Important Notes:

  • The code in this repository is for learning purposes only and is not intended for real-world use.
  • It may be deleted or changed at any time without prior notice, so be sure to use it while it's here!
  • This is just a simple example to help you understand how these concepts fit together in an application structure.

Why should I use this?

  • If you're learning about software architecture, this repository can give you a practical example of how to structure an application.
  • It also provides a basic understanding of how different layers in an application work together, especially when connecting to a database.

How to Use This Code:

  1. Clone or Download: You can clone or download the repository to explore the code.
  2. (Optional) Install Microsoft.SqlClient package from Nuget Package manager
  3. Study the Code: Look at how the database is connected and how the three-layer model is set up.
  4. Modify and Experiment: Feel free to modify the code for practice, but remember that this code is not for production use.

How to Use TODO-To-Issue tracker:

  1. In the repo where you want the action to run, go to Settings -> Actions (General) -> Workflow permissions and enable "Read and write permissions".
  2. Simply add a line or block comment starting with TODO (or any other comment identifiers configured), followed by a colon and/or space.
  3. For more info follow https://github.com/marketplace/actions/todo-to-issue
