Eloquera project was started in 2008 by Jay Haybatov and Dmytro Bablinyuk, and first shipped in 2009.
In 2010 first commercial applications with Eloquera were shipped.

• Storing any .NET object without implementing any interface or inheriting from a specially designed class
• Queries based on SQL and LINQ
• Returns the objects in their native form, as a single object or as an enumeration
• Supports arrays in queries. Any arrays - simple, multidimensional, jagged, of simple or complex types
• Supports JOINs in queries
• Expressions and functions in queries. You can perform JOINs or sort your data on them
• Regular Expressions
• Inheritance support in queries (SELECT ParentClass returns both ParentClass and ChildClass)
• Queries only upon certain type. (SELECT ONLY ParentClass returns only ParentClass, but not ChildClass)
• Restoring objects partially (you might need ForumTopic object, but don't need all TopicMessage, linked with it)
• Depth for queries
• Client/server architecture
• Parallel and independent query execution for multiple users
• Windows authentication
• Both Server and client are implemented in 32- and 64-bit architectures
• Unique identifier for any object within a database - for stateless environments (hence ASP.NET)
• Different cultures support in queries (e.g., "where dates BETWEEN['en-US'] @d1 and @d2" - formats will be treated as US English, even with the current UK settings on the machine)
• Approximate matching with ALMOST keyword

Eloquera provides variety of support plans
