"LINQ for db4o is extremely easy to use and very
powerful. The learning curve is very low. This
article [about db4o and LINQ] only scratched the surface of the
possibilities of db4o."
Edwin
Vermeer
Senior Software Developer, Mirabeau B.V.
"Embarcadero Technologies' acquisition of
CodeGear and the announcement of db4o's support of LINQ are more
evidence of the blurring of the lines of application development and
database development. Increasingly, application developers want and
need better insight and control of the data management aspects of
their applications. On the flip side, database administrators are
faced with responsibility of ensuring application performance. Common
toolsets and better communication can only help both communities
achieve their objectives."

Keller on MetaFrequency

(either with a server db4o database or a relational database)
-
Download
dRS and try it on Android now!
-- db4objects is Leading a Community Effort to Promote LINQ for Java --
-
LINQ for Java follows db4objects approach of Native Queries. To know more about

topics. Check it out, and start downloading
here or
watch live.
-
The tagging system on the right helps you find the "paircast" that addresses
your topic of interest.
