by Sébastien Finot | September 2013 | .NET Enterprise Articles Microsoft

In this article by Sébastien Finot, the author of the book "Building Interactive Queries with LINQPad", a brief introduction to LINQ and how it can be used has been discussed. LINQPad is a free IDE (Integrated Development Environment) that allows you to create programs and query databases. Language Integrated Query (LINQ) consists of a set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic.

To introduce you to LINQ, we will first look into a non-LINQ example so that we can have a point of comparison.

Introduction to XenConvert

by Gohar Ahmed | September 2013 | Enterprise Articles

In this article by Gohar Ahmed, the author of Implementing Citrix XenServer Quickstarter we will learn about XenConvert.

Citrix XenConvert is a tool to convert physical machines to virtual machines; that is, a Physical-to-Virtual (P2V) conversion tool. It converts a Windows-based workload from a server or desktop machine to a virtual machine in a XenServer, virtual appliance, virtual disk, or virtual disk connected to Provisioning Services.

A conversion involves copying the contents of the workload and configuring its operating systems for XenServer. So, the workload can be applications and data besides the base Windows operating system. XenConvert can convert from a single server or desktop (physical machine) running Windows to a provisioned virtual disk or VHD that Provisioning Services can import.

A good scenario would be converting a physical Windows server with all the applications hosted in it to a virtual machine for pre-staging, so that the hosted applications' behavior can be tested after adjustments. This can be the operating system upgrade or application updates/upgrades.

SQL Server Integration Services (SSIS)

by Debarchan Sarkar | September 2013 | Enterprise Articles

In this article by Debarchan Sarkar, the author of Microsoft SQL Server 2012 with Hadoop, we will learn how to create an SQL Server Integration Services package to move data from Hadoop to SQL Server using the Hive ODBC driver.

Microsoft SQL Server is a complete suite of tools that include an RDBMS system, a multidimensional OLAP and tabular database engines, as well as other services, for example a broker service, a scheduling service (SQL Agent), and many more. As discussed it has become extremely important these days to integrate data between different sources. SQL Server also offers a powerful business intelligence stack, which provides rich features for data mining and interactive reporting. One of these BI components is an extract, transform, and load (ETL) tool called SQL Server Integration Services (SSIS). SSIS offers the ability to merge structured and un-structured data by importing Hive data into SQL Server and apply powerful analytics on the integrated data. Throughout the rest of this article, we will get a basic understanding on how SSIS works and create a simple SSIS package to import data from Hive to SQL Server.
