  1. 1. 1SkyDrive1.INTRODUCTION:- Sky drive(officially Microsoft sky drive, previously “windows live sky drive”and windows live folders) is a file hosting service that allows users to upload and sync files to acloud storage and then access them from a web browser or their local device. it is part to thewindows live range of online services and allows users to keep the files private, share them withthe contacts, or make the files public. publically shared files do not require a Microsoft accountto access. the service offers 7GB of free storage for new users.Additional storage is available forpurchase. Users who signed up to sky drive prior to April 22, 2012 cloud opt - in for a limitedtime offer of 25GB of free storage upgrade. the service is built using HTML5 technologies, andfiles up to 300MB can be uploaded via drag and drop into the web browser,or up to 2GB via theSkydrive desktop application for Microsoft windows and os x.

  2. 2. 2SkyDrive2. HISTORY:- On its launch, Sky drive known as a Windows Live Folders at the time (with aCodename of Sky Drive), was provided as a limited beta available to a few testers in the UnitedStates. On August 1, 2007, the service was expanded to a wider audience. Where windows livefolders are nothing but the folders with the windows start button logo, which indicates that thefiles and the data that are present in that folder are stored in cloud and if we want we can storeadd the folders to that folder such that they are stored at cloud storage. Fig live folder. Shortly after, on August 9, 2007 the service was renamed Windows Live Sky Drive andmade available to testers in the United Kingdom and India. As of 22 May 2008 Sky Drive wasavailable to 62 countries and regions. On December 2, 2008,the capacity of an individual Sky Drive account was upgraded from5 GB to 25 GB,and Microsoft added a separate entry point called Windows Live Photos whichallowed users to access their photos and videos stored on Sky Drive. This entry point allowedusers to add "People tags" to their photos,download photos into Windows Live Photo Galleryor as a ZIP file, as well as viewing EXIF metadata such as camera information for the photosuploaded. Microsoft also added full-screen slide show support for photos using Silver light.DEPT OF CSE,VITW
  3. 3. 3SkyDrive SkyDrive was updated to "Wave 4" release on June 7, 2010, and added support for OfficeWeb Apps, offering versioning support. In this update, due to the discontinuation of Windows,the ability to synchronize and share bookmarked Web links between users via SkyDrive has alsobeen discontinued. On June 20, 2011, Microsoft overhauled the user interface for Sky drive, built using HTML5Technologies. Microsoft also doubled the file size limit from 50 MB to 100 MB per file, as wellas adding new features such as caching and hardware acceleration, support for HTML5 videos,Quick views , cleaner arrangement of photos , infinite scrolling. This update also broughtTogether the different entry points for Sky Drive, such as Windows Live Photos and WindowsLive Office, into one single interface. On December 3, 2011 , Microsoft released a SkyDrive for iOS app, and a SkyDrive forWindows Phone app , which are available in the App Store and Windows Phone Marketplacerespectively. On April 22 , 2012 , Microsoft released a Sky Drive desktop app for WindowsVista, Windows 7, Windows 8, and OS X users which allows them to synchronize files onSkyDrive, much like Windows Live Mesh, as well as allowing users to "fetch" files on theircomputer via the web browser. On August 14, 2012, Microsoft announced a new update for SkyDrive which broughtchanges and improvements to, SkyDrive for Windows desktop and OS X, andthe SkyDrive API as part of Live Connect. For, the updates brought a new"modern"design for the web service consistent with,and along with the UI updatethe service also received improvements such as instant search,contextual toolbar,multi-select inthumbnail view, drag-and-drop files into folders, and sorting improvements. On August 28, 2012, Microsoft released a Sky Drive app for Android on Google Play store. On September 18, 2012, Microsoft also introduced a recycle bin feature on Sky Drive and announced that Sky Drive will support the creation of online surveys via Excel Web App.DEPT OF CSE,VITW
  4. 4. 4SkyDrive3.BASICUSE:- The main basic uses of using skydrive are as follows:-  The main use here is instead of using a pen drive of a usb drive we can store our files in the cloud .  We can access the files anytime and anywhere by using web browsers like chrome and by using smart phones and tablets which has an internet connection.  As we are creating and stroing the files in the cloud we can access the files and sync the files from anywhere.the following figure shows it diagrammatically. Fig accessing.  Not only fro videos and photos we can also create  Word document.  Powe point document  One note documents.  By using the “WORD WEB APP” which is a service offered by the skydrive to create a word documents and power point documents and also one note documents easily.  “WORD WEB APP” is the type of the services offered by the cloud computing which is nothing but the SaaS(software as a service).DEPT OF CSE,VITW
  5. 5. 5SkyDrive  Not only creating and storing we can also share by using sharing option present in the skydrive.  The steps to follow to share the file such that to whom you want to share the file and to which people who can edit and also download and see is as follows:- - First select the file or any data that u want to see - Now on the left side pane you will get the info about the file that you have selected and also option as sharing. - Now click on share button and then enter the email address of the person for whom you want to share the file or documents and then press on dome hence the sharing is done successfully. - now by clicking on the file, on your left side you can see the person/persons for whom you have shared the file.  The same steps are followed for any kind of file that you want to share from skydrive.  There is another option we can see in the skydrive is “GROUPING” where You can shre the file or a document to a group of persons at a time.  There is another option where the Microsoft had provided recently that is at the Time of recent release is the “recycle bin”, where you can see the files that are deleted recently from your sky drive.DEPT OF CSE,VITW
  6. 6. 6SkyDrive HOW SKY DRIVE IS ACCESSED:- sharing in sky drive. Fig 3.File There are two ways how we can access the sky drive are:- 1)Windows live sign in. [] 2) []  if we have the windowslive id hence we go to this web page sign in to access the sky drive.DEPT OF CSE,VITW
  7. 7. 7SkyDrive Fig live sign in/signup page.  If you don’t have the account then just click on sign up and fill the simple form with details and then the account is created. and the form look like as follows.DEPT OF CSE,VITW
  8. 8. 8SkyDrive Fig 5.signup form.  it is the official site for thwe sky drive where u can have a sign field,where you can sign in your account to access your date and store the data in cloud.  The microsofts had been proving this iste from recent years since from last 2 years but in October 2012 ,the site had been updated by using new technologies and with rich graphics where the user can access the site very easily and effectively..  after successful sign in by using any of the above methos the home is look likes as follows if you have some files.DEPT OF CSE,VITW
  9. 9. 9SkyDrive Fig 6.home page of sky drive with some files.  The files and folders that are present in your storage are displayed after signing into your account.  The Microsoft’s had used some of the technological modifications that are used here in the website of sky drive in such a manner that the pictures that are in the folder are represented after sign in as a slide show which is very comfortable and had a cool look to the user how is using it.4.STORAGE ISSUES  As we had seen that the skydrive saving the data in clouds, but the generalDEPT OF CSE,VITW
  10. 10. 10SkyDrivedoubt for a layman is how they are storing the data in cloud?. Is the cloud had any storagedevice to store data? and so on…  But the issue here is the skydrive stores the information in cloud storage asstored by all the cloud services which are following the cloud computing technology to store andto retrieve the data.  The cloud architecture is the common architecture which are used by the all thecloud storage provides including the skydrive also. the basic architecture is as follows:- Fig architecture  Desperate computer owners might delete entire folders worth of old files inorder to make space for new information. But some are choosing to rely on a growingtrend: cloud storage..  While cloud storage sounds like it has something to do with weather fronts andstorm systems, it really refers to saving data to an off-site storage system maintained by a thirdDEPT OF CSE,VITW
  11. 11. 11SkyDriveparty. Instead of storing information to your computers hard drive or other local storage device,you save it to a remote database. The Internet provides the connection between your computerand the database.  On the surface, cloud storage has several advantages over traditional datastorage. For example, if you store your data on a cloud storage system, youll be able to get tothat data from any location that has Internet access. You wouldnt need to carry around a physicalstorage device or use the same computer to save and retrieve your information. With the rightstorage system, you could even allow other people to access the data, turning a personal projectinto a collaborative effort.  The some of the service soffered by the cloud computing are as follows:- 1)Infrastructure as a service (IaaS) 2)Platform as a service (PaaS) 3)Software as a service (SaaS) 4)Network as a service (NaaS) 5)Storage as a service (STaaS) 6)Security as a service (SECaaS) 7)Data as a service (DaaS) 8)Database as a service (DBaaS) 9)Test environment as a service (TEaaS) 10)Desktop virtualization 11)API as a service (APIaaS) 12)Backend as a service (BaaS) .  To provide the software as a aweb app and storage of data sky drive did notuses the all the above services,it onlu uses the main services that all the other sky storageproviders are following.  The main two services provided by the sky drive are SaaS and DBaaS.DEPT OF CSE,VITW
  12. 12. 12SkyDrive  To provide the online word and power point apps the sky drive uses the SaaSsuch that we can use the ms word and power point and much more which are present in actuvalms office as a software service. Fig 8 .SaaS architecture.  The sky drive uses the another service called DBaaS to store and Accessing of files from anywhere and at any time.DEPT OF CSE,VITW
  13. 13. 13SkyDrive  The structure of the DBaaS is of follows:- Fig 9.DBaaS architecture.  The service interface act as a a3rd party for storing the data which isgiven by the user and it can be retrieved by the user later.  The clients gives the data which is only required such that the data thatare given the documents and the power points are received by the applications gives that data tothe service interface and it stores in the databases and gives the information whenever theuser wants.DEPT OF CSE,VITW

It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML4 as of 1997) and, as of December 2012, is a W3C Candidate Recommendation. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but XHTML 1 and DOM Level 2 HTML as well. Html5 adds many new syntactic features. These include the new <video>, <audio> and <canvas> elements, as well as the integration of scalable vector graphics (SVG) content (that replaces the uses of generic <object> tags) and Mathml for mathematical formulas. These features are designed to make it easy to include and handle multimedia and graphical content on the web without having to resort to proprietary plug-in and APIs. Other new elements, such as <section>, <article>, <header> and <nav>, are designed to enrich the semantic content of documents. New attributes have been introduced for the same purpose, while some elements and attributes have been removed. Some elements, such as <a>, <cite> and <menu> have been changed, redefined or standardized. The APIs and document object model (DOM) are no longer afterthoughts, but are fundamental parts of the HTML5 specification. HTML5 also defines in some detail the required processing for invalid documents so that syntax errors will be treated uniformly by all conforming browsers and other user agents. AJAX Ajax ( AJAX; an acronym for Asynchronous JavaScript and XML)is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously (in the background) without interfering with the display and behavior of the existing page. Data can be retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not required (JSON is often used instead), and the requests do not need to be asynchronous.Ajax is not a single technology, but a group of technologies. HTML and CSS can be used incombination to mark up and style information. The DOM is accessed with JavaScript toDEPT OF CSE,VITW
  15. 15. 15SkyDrivedynamically display, and to allow the user to interact with the information presented. JavaScriptand the XMLHttpRequest object provide a method for exchanging data asynchronously betweenbrowser and server to avoid full page reloads.JSON JSON or JavaScript Object Notation, is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representingsimple data structures and associative arrays, called objects. Despite its relationship toJavaScript, it is language-independent, with parsers available for many languages. The JSON format was originally specified by Douglas Crockford, and is described in RFC4627. The official Internet media type for JSON isapplication/json. The JSON filenameextension is .json. The JSON format is often used for serializing and transmitting structured data over anetwork connection. It is used primarily to transmit data between a server and web application,serving as an alternative to XML. VIRTUVALIZED LIST VIEWS The virtual list view (VLV) control is a type of supportedControl that canbe attached to a search operation to indicate that only a subset of the results should be returned. Itmay be used to iterate through the search results a page at a time. The virtual list view (VLV) control is similar to the simple paged resultscontrol with the exception that it can be used to retrieve an arbitrary subset of the results from theserver, and it requires that the search request also include the server-side sort control to ensurethat the results are consistently sorted across requests.
