Does .NET With LINQ Beat Java?


Framework's data query capabilities give it an edge, experts claim.

There is a question some developers are asking: Has LINQ given Microsoft’s latest .NET Framework an edge over Java? Industry experts say “yes,” but with some caveats.

Microsoft shipped Language Integrated Query as part of the .NET Framework 3.5 in November. LINQ was originally one of many research projects that the company has under way. LINQ integrates query concepts directly into .NET programming languages using a syntax that is similar to SQL, to simplify the querying of data, objects and XML.

Patrick Hynds, president of security consultancy CriticalSites, said that LINQ is “an object-oriented revolution for data,” because it, like object-oriented programming, allows programmers to write code that is more like the way people think.

Before LINQ, he explained, developers had to adapt to a particular programming language’s precepts of the way data was organized and accessed. “One of the key things that I found about Java is that it has been very comfortable to make the developer conform to what ‘they’ [Sun and The Java Community Process executive committee] thought that the developer should use,” Hynds noted, adding that Microsoft’s LINQ implementation deals with data in a more “conversant” way.

Hynds is a regional director of the Developer Platform evangelism group, volunteers recognized by Microsoft for technical expertise.

Other Options
RedMonk analyst Stephen O'Grady noted that while there may not currently be equivalent functionality within the Java platform, there are options for Java persistence that offer “LINQ-like functionality,” naming db4objects as an example.

Db4objects is an open-source object database for Java and .NET developers, which uses a technology called Native Query that can optimize native language constructs into queries, without relying on a particular language’s syntactical extensions.

Jonathan Bruce, program manager for .NET technology group at DataDirect Technologies, and formerly JDBC specification lead and architect for the Java platform at Sun, said that developers are “clearly excited” about what Microsoft has come up with, but cautioned that it is not as original as they make it out to be.

There is a LINQ equivalent in Java: https://github.com/nicholas22/jpropel-light. The syntax is almost exactly the same: String[] names = new String[] { "james", "john", "john", "eddie" }.where(startsWith("j")).distinct();
