NASA Earth Observatory Dataflow Diagram for illustrating notation The dataflow diagram above is taken from the Acme Fashion feasibility study. It's the top level (aka level 1) current physical version. It's a good enough basis to describe the notation used in DFDs, though doesn't show every variant (see Dataflow Diagram Variants later on the page) of each symbol in use. Enclosing box The enclosing box represents the scope of the area under study on this DFD. For the top level DFD, as shown here, in the boxed-off area at the top goes the project name or some derivative of it and the DFD variant (i.e. External Entities External entities represent people, IT systems, or other organisations that are external to the system under study and are the source / recipient of data. Note that if an external entity is an IT system, then you're talking about some form of interface, maybe manual, maybe automated. To help stop the confusion caused by crossing lines on the diagram, it often helps to use the same external entity more than once. Processes Making up the numbers

Scarlet Mist - buy/sell spare music gig and Festival tickets ethically The RIAA Situation- Explained. | The RIAA Took My Baby Away | Jukebox, my music player application for Facebook, has over 44,000 songs in its database. It originated as a project I wrote just for fun this summer, mainly because I was bored and because I wanted to play with the Facebook API. I was pretty disappointed with the other popular music apps at the time, and thought I could contribute something. With that said, it probably should have come as no surprise to me that my program would eventually gain the attention of the RIAA. I knew this, but I also didn’t think it would happen to Jukebox. The letter came anyway. Is it any surprise that a corporation that proudly boasts that it represents “approximately 90% of all legitimate sound recordings produced and sold in the United States” can claim any music sharing service online infringes on their copyrights? My housemate and good friend Rich connected me to a lawyer at Harvard Law School, Sam Bayard. It was just not feasible for me to sort out this entire issue in 48 hours.
Google Earth brings virtual tourism to iPhone | Apple - CNET News Correction made on October 27 at 9:40 a.m. PDT: See details below. SAN FRANCISCO--Google already has customized some of its Web sites for display on the iPhone, but now the company also dived headlong onto Apple's highly regarded mobile phone with a full-fledge application, a handheld version of its Google Earth geographical software (download for Windows and Mac). Google Earth lets people virtually fly around a 3D view of the world made from satellite and aerial imagery mapped onto the planet's mountains and valleys. The iPhone version reproduces this core experience, downloading imagery from Google's servers as the perspective shifts and dotting the map with landmarks, photos, and other information. "The idea of having Earth on a mobile device is something people dreamed of back to the Keyhole days and before," said Peter Birch, Google Earth's product manager, referring to the satellite imagery company Google acquired in 2004. "Macs have multitouch on them," Birch said.
How To Win Buy In For Social Media You know that skeptical marketing manager, brand manager or even CEO you’re kind of intimidated by? The one who rolls his or her eyes when the word, “blog,” is used in a sentence. The one that is constantly asking for the ROI of his or her social media spend in a tone that makes you certain you won’t be included in next year’s budget? I think I’ve figured out how to win him or her over. Last week I had a meeting scheduled with that guy. While at first it seems like you need to talk philosophy and theory on what and why social media is and how social media works, that’s not always the right approach. “Let me show you ooVoo,” I said. The client got agitated. “Why haven’t you shown me this before now? I thought for a brief moment and realized the answer. “Because I don’t live in your world.” This marketing manager has a distaste for communicating with people sans visual context. I won’t stop preaching that social media isn’t about the tools. How do you win buy in?
