REAL-WORLD SQL

Reference Applications

Dofactory SQL comes with 2 comprehensive applications which allow you to experience the data patterns first hand in a real-world application environment.

Below are a few screenshots of the Training App which is a sample .NET application designed for software training companies.

PATTERNS IN ACTION

Visually explore the benefits of Data Patterns



This may seem strange, but numerous SQL patterns have a visual manifestation in the UI. Those that do are marked with a icon in the application. Hovering over these icons will display a tooltip that shows which pattern(s) are at work. As you can see below, many patterns (7 on this page alone) do have an impact on the user experience.



DATA MODELS

Well-designed data models and ER diagrams included.

Available throughout the package.
