Eloquera Database - the web-oriented client/server object database for .NET
Eloquera Database 2.0 (codename Woomera) - the web-oriented client/server object database for .NET. It is already available as a pre-release version on the website http://woomera.eloquera.com
The upcoming version of Eloquera database has some mind-boggling features, and I would like to give a brief list of its main features.
* Storing any .NET object without implementing any interface or inheriting from a specially designed class.
* Queries based on SQL. Yep, good old SQL. And no SQL database is required.
* 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. And there is more!
* Supports JOINs in queries. And even for arrays.
* Expressions and functions in queries. You can perform JOINs or sort your data on them.
* Flexible sorting - there are some really useful ones.
* Regular Expressions are your best friends! Regex support in queries.
* Indexes. Yep, you can index data for faster access. Both fields and properties.
* Bulk inserts and updates. You can insert tens of thousands objects in a second.
* Generic object support. And also in queries.
* 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. Specify no user name and log on under your current account.
* 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.
Have you seen an object database with SQL query support? With JOINs? And with arrays?
