LightSpeed by Mindscape

URLs: lightspeed, mindscape

Fast .NET domain modeling and persistence. Mindscape LightSpeed is a high performance .NET domain modeling and O/R mapping framework. LightSpeed has first class LINQ support, Visual Studio 2008 and Visual Studio 2010 designer integration and a high performance core framework which means you can create rich domain-driven models more quickly and easily than ever before. Buy Mindscape LightSpeed with Source Code to obtain the LightSpeed O/R mapper source too. Mindscape LightSpeed 12 months Subscription also available when purchased as part of Mindscape Mega Pack.

LightSpeed O/R mapper is an object relational mapping framework that supports domain driven development and works with both Visual Studio 2008 and Visual Studio 2010.

Mindscape LightSpeed O/R mapper provides querying via a LINQ provider that works seamlessly with SQL Server 2000, 2005, 2008, Oracle 9+, PostgreSQL, MySQL, SQLite, VistaDB, Amazon SimpleDB and DB2.

The Visual Studio designer supports drag and drop design time modeling for all the databases supported by LightSpeed. It includes full schema round tripping meaning that developers can work in a model-first approach or a database-first approach - or even mix and match. The LightSpeed designer will synchronize changes as they are made.

To help manage deployment scenarios, Mindscape LightSpeed includes a visual migrations framework that can be operated directly from within Visual Studio or the command line. This makes managing schema changes a breeze and means developers can be more productive.

LightSpeed O/R mapper also supports:

Second level caching

Object property-level change tracking

Efficient database insert/update batching

Multiple identity type support

Single table inheritance, Class table inheritance and Concrete table inheritance

Domain driven concepts such as ValueObject, Aggregates, etc
