Introducing LINQ

by Cecille Ramirez on April 21st, 2010

Several years back, the only technology Microsoft developers use to work with database is ADO. Microsoft has a new baby that comes with their Visual Studio called LINQ.

LINQ stands for Language Integrated Query. The idea of LINQ is to address database development in the context of Object Oriented Programming development model. LINQ has a great power of querying relational, object and XML data. Microsoft categorizes it into three parts.

1.LINQ to Object (those that are in-memory cache)
2.LINQ to ADO .NET (relational)
3.LINQ to XML (xml source)

If you know SQL querying, LINQ will be easy to learn. Below are the nicest things with LINQ:

1.No more CRUD development since you are guided as you type your code thru the Visual Studio intellisense
2.No more grueling hunt for object name change like table name references by the LINQ code
since build errors can be easily followed and corrected thru debugging

LINQ as a whole is exciting and an entirely new technology which I truly believe has good potential and will be around for a long time just like the ADO. Both of these technologies will be the platform for database development in the .NET platform.

LINQ is included in the Visual Studio 2008 with codename ORCAS.  There are virtual images that have ORCAS in it to sample your first LINQ programming. Check out the Microsoft website for more details where to download it.  It should be “Visual Studio Orcas”!

The instructor [Al Khalfan] was very knowledgeable in the field. He presented the materials and concepts with a professional touch. He also frequently adds humor to his teachings, which made it easier for me to understand. The support staff was all nice, gentle, caring, and very helpful. The materials, rooms and amenities were excellent and exceeded expected standards.

Employer Partner Feedback

Dawn has been a pleasure to work with. She is diligent in her efforts to give MicroTrain’s students the best opportunities to connect and network with various companies and players in the job market. The curriculums and certification programs are in line with today’s current IT needs. It’s good to see that they evolve with what employers are most seeking out there. I would recommend to any employer that hires skilled IT workers that they look into MicroTrain’s career services department as a potential source of candidates. The business of hiring can be quite costly, and Dawn and her staff provide a free service to outside companies. This value-add for MicroTrain’s students aligns with their mission in both training and job assistance to set up a win/win scenario for all involved.
