.NET DataStore

Rapidly Build .NET Projects with DataWindow Technology.

The 。NET DataStore is a pure C# implementation of DataWindow technology and compatible with a cloud native architecture。 It allows developers to code C# projects with essentially all the non-visual features and productivity of the DataWindow。 A tool is also provided to automatically convert any existing PowerBuilder DataWindows (including child DataWindows) to 。NET。

Highly Productive

Easy to Learn - The .NET DataStore provides virtually the same APIs (properties, methods and events), data buffers, and approach to transaction management as PowerBuilder.
Minimal Coding - The 。NET DataStore requires few lines of code to accomplish big tasks。 It also encapsulates all SQL in its C# POCO model to avoid redundant code。
Automatic Conversion - An automated conversion tool (the DataWindow Converter) generates standard C# POCO models from existing DataWindows including the child DataWindows.

Standard Architecture

Model-Driven - Driven by a standard C# POCO model that contains all data-related properties and attributes. There is a strict separation of concerns and no proprietary .SRD format.
Managed Code - 100% managed code so it benefits from the full power of the Common Language Runtime (CLR), such as built-in security, faster performance, and ease of deployment.
.NET Core - Compatible with the .NET Core framework. You can deploy to either Windows or Linux OS running a variety of Web servers or even go serverless.

Open Design

Open-Source - All the .NET DataStore library code is available in C# source code form in addition to the compiled NuGet packages.
Any C# IDE - You can maintain the .NET DataStore in any C# IDE, such as Visual Studio or SnapDevelop.
IList Compatible - The .NET DataStore inherits from a standard .NET list, enabling you to natively integrate with other .NET code and libraries.
