CarShop .NET Core Blazor Project – Part 1

Over the past few months I have been working on a sample project, which will eventually be published to my GitHub repo. The project specifically focusses on Microsoft Entity Framework with an Azure SQL database and also utilises Blazor as the underlying UI and logic layer, including DevExpress for Blazor UI components. This is an initial post which describes the project and it’s capabilities.

The CarShop project was envisioned from wanting to build something new and then work on multiple articles rather than only a few for a project, for part of this year. This will enable me to provide updates at various intervals and at some stage, including the publishing of the code.

Why a CarShop?

Since I am car fan and have been for many years, I thought this would be an exciting project to work on this year. With Blazor + .NET and DevExpress being some of my favorite development frameworks, I thought this would be ideal as a project.

The database schema

Since I am using the Microsoft Entity Framework in the Blazor Visual Studio project, the schema was exactly where I wanted to start. As the iterations developed, I decided to go straight into Azure SQL to provision my tables, entities and relationships, primary keys and foreign keys etc. The project needs to store car details (at a basic level), customer details, car manufacturers, car models, fuel types, engine sizes etc. Whilst it is a simple model to start with, it’s relatively simple to expand the schema as I see fit, both from the SQL backend as well as the coded elements and data classes.

For this post I will show an example of the schema, which is below, produced by dbForgeStudio 2022 for SQL Server.

CarShop Schema – Developed using dbForgeStudio 2022 for SQL Server

Since this is a relatively simple sample project, the data is held in a single Azure SQL database. As you can see, the Vehicles table has the most relationships with car fuel types, vehicle status, engine size, colours, models and manufacturers. For the customers table, I’ve kept the design simple for now although I intend to expand this into a scenario where there may need to be some data quality checks and periodic checks around when the customer data was last updated, for reasons I will include in a future post.

Part 2 will focus on the Transact-SQL, so that the schema can be provisioned.

Architecture; how does it save money and reduce risk in an organisation?

Recently I was was asked how architecture saves money and reduces risk in an organisation. I had 15 minutes to present a simple answer and demonstrate an example of how high-level analysis improves overall costs and reduces the risks as well as explain the challenges.

I created a presentation to describe this topic, with the agenda below.

1 – What is Architecture?

2 – Business challenges without architecture?

3 – Why is architecture important?

4 – Real world example, shaping the architecture

5 – How architecture reduces risks and costs?

6 – The Endgame

The presentation is available to download here.
