This article reviews how to modify an SQL query to group related rows together to provide summary statistics database information and introduces the concept of a view, which can be used to simplify database application development by creating a virtual table that represents the results of an SQL query. Also learn about database indexes, which you can use to locate specific table rows. After you've mastered these advanced database concepts, you'll be well positioned to begin developing Java database applications with Apache Derby.

"Many of us who tried out the Windows Phone 7 simulator were disappointed to discover the simulator didnât contain a lot of the functionality that was being shown off at Mix10. It turns out Dan Ardelean has published a modified or 'unlocked' version of the simulator that contains virtually everything that was displayed. The front page is now full of apps that work, the settings menu is a long list of options for those apps. Unfortunately the download of the .bin file has now been pulled, but I was lucky enough to get a copy. Check out the 10 minute video of Windows Phone 7 [plus another video]." It even has a nice task manager and file explorer - undoubtedly for testing purposes. It's Windows CE 6.0, after all.

"There has been much speculation over what OS 6.0 could possibly look like. We were recently hit with these images of what appear to be of a device running OS 6.0 with a similar screen resolution of a storm or storm2. These spy shot images come highly regarded as real from one our best connects. We're hoping to see it soon on a physical device and so until then take from it what you will."

"The city of Amsterdam has been involved for several years in building Citynet, a partnership between the city and two private investors to wire 40000 Amsterdam buildings with fiber. And it's not just fiber, it's open access fiber - any ISP can sign up to use the infrastructure and deliver ultra-fast Internet access. In 2008, the European Union ruled that the city's involvement in the project was in fact legal, and that it was not improperly interfering in the market. We asked Herman Wagter, CEO of the company that built Citynet fiber project, to talk about how he got the job done, and to explain the challenges of rolling out fiber in a densely crowded European city." In case you're wondering: no, I don't live in Amsterdam. My small hick town has plans for fibre too, however.
