    SqlClientDAC for Delphi

    A feature-rich and high-performance data access components for MS SQL

    SqlClient Data Access Components (SqlClientDAC) is a feature-rich and high-performance library of components that provides native connectivity to SQL Server from Delphi. SqlClientDAC-based applications connect to SQL Server directly through the ADO.Net SqlClient, which is a .NET Framework Data Provider for SQL Server. SqlClientDAC is designed to help programmers develop faster and cleaner SQL Server database applications. SqlClientDAC uses its own protocol to communicate with SQL Server. SqlClientDAC is lightweight and performs well because it is optimized to access a SQL Server directly without adding an OLE DB or Open Database Connectivity (ODBC) layer. SqlClientDAC, a high-performance and feature-rich SQL Server connectivity solution, is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server.

    neural network designer

    neural network designer

    a dbms for neural nets. Chatbots, DTrees, random forests, n-grams,...

    This project consists out of a windows based designer application and a library (that can run on multiple platforms, including android) together with several demo applications (including an MVC3 chatbot client and an android application). It is probably best compared to a database management system, but for neural networks instead of relational data. As such, the library is optimized for handling any type of data-size by using advanced streaming and caching algorithms. With the designer, you are able to create different types of decision trees, random forests, n-grams, pattern-matchers, conversational agents and all sorts of AI related algorithms. You can combine statistical approaches as well as pattern matchers or others. Do natural language processing, image or data analysis & interpretation,...

    ASP.NET API Versioning

    ASP.NET API Versioning

    Libraries which add service API versioning to ASP.NET Web API

    ASP.NET API versioning gives you a powerful, but easy-to-use method for adding API versioning semantics to your new and existing REST services built with ASP.NET. The API versioning extensions define simple metadata attributes and conventions that you use to describe which API versions are implemented by your services. You don't need to learn any new routing concepts or change the way you implement your services in ASP.NET today. The default API versioning configuration is compliant with the versioning semantics outlined by the Microsoft REST Guidelines. There are also a number of customization and extension points available to support transitioning services that may not have supported API versioning in the past or supported API versioning with semantics that are different from the Microsoft REST versioning guidelines.

    ASP.NET PDF Viewer by GroupDocs

    Secure, Browser-Agnostic ASP.NET PDF Viewer with DRM Features

    This sample project is created by the GroupDocs showcase team to demonstrate key benefits of an ASP.NET PDF viewer built using the commercial library – GroupDocs.Viewer for .NET. The viewer allows you to display PDF documents across all standard web-browsers (IE8+, Chrome, Mozilla Firefox, Safari 5+, Opera, etc.) without having to install any software or plugins on end-user machines. Another core feature – is the ability to display PDFs in a read-only mode, so that end users can’t download, print or copy original PDF files while viewing them in a browser. Please note that GroupDocs.Viewer for .NET is a paid library. In order to setup and run this project, you will need to download the GroupDocs.Viewer for .NET library from the GroupDocs website. For more details on the sample ASP.NET PDF viewer and to download the library, please read this article: > http://groupdocs.com/blog/asp-net-pdf-viewer-built-based-on-the-groupdocs-viewer-for-net-library
