Valentina is cross-platform SQL and non-SQL columnar database that allows development of client-server [Web] solutions and applications with an embedded local database using the same sources.

It supports disk and in-memory databases, and field types including Bit, BLOB, Pictures, and Enum. It provides advanced features such as triggers, views, stored procedures, regular expressions, XML, full-text search, and calculated fields. It exists as Valentina Server, Valentina Studio, and a set of Valentina ADKs for all major programming languages.

Itzam/Sharp is a C# class library for creating and manipulating keyed-access database files containing variable-length, random access records. Information is referenced by a user-defined key value; indexes may be combined with or separate from data. Itzam/Sharp implements the Itzam engine (see Itzam/Core and Itzam/Java) in 100% managed C#. At 32K, the Itzam/Sharp engine is both small and powerful, and it works with any .NET language, including F# and Visual Basic.
Vici MVC is a MVC Web application framework for .NET 2.0 or higher. It runs on the low-level ASP.NET layer provided by the .NET framework, but does not use ASP.NET WebForms and Controls. The framework is controller-centric as opposed to the view-centric architecture of ASP.NET WebForms. This allows Web applications to be built according to the MVC pattern with minimal effort. Vici MVC emphasises complete separation of concerns, ease of use, minimal configuration requirements, integration with any data access technology, performance, and easy deployment ("XCOPY deployment").
