  4. 4. 1. Introduction<br />Symbian’s Introduction<br />The Smartphone operating system Symbian OS is produced by the software development and licensing company Symbian Ltd.<br /> Symbian Ltd was established in June 1998 and is headquartered in Southwark in the UK, and the current CEO is Nigel Clifford.<br />By Parimal Patel,CSE dept.<br />
  5. 5. 1. Introduction<br />Research<br /><ul><li>We had in mind Symbian’s background, the whole history and development behind this operating system, his capabilities, security, performance and so on.
  6. 6. Hardware support and connectivity were, as well, one of our research points.
  7. 7. The native language of the Symbian OS is C++, there for, our research will passes through the programming languages that can be used on Symbian.</li></ul> The advantages and limitations will be the last tasks we’ll talk about.<br />By Parimal Patel,CSE dept.<br />

  36. 36. 3. Software development<br />3.2 IDE and Tools<br />What is IDE* ?<br /> An IDE is a software application that allows the computer programmer to develop software for a certain platform. An IDE normally has a: source editor, compiler and/or interpreter anddebugger.<br />*Integrated Development Environment or also known as integrated design environment or integrated debugging environment.<br />By Parimal Patel,CSE dept.<br />

  40. 40. 3. Software development<br />What tools are needed:<br />By Parimal Patel,CSE dept.<br />
  41. 41. Programing languages<br />Symbian OS offers a choice of programming languages to the developer. Symbian OS is written in C++ , and this is therefore regarded as its primary programming language.<br />By Parimal Patel,CSE dept.<br />
  42. 42. Programing languages<br />Java 2nd the most important programing language on Symbian OS.<br /><ul><li>Others programing languages which you can use on Symbian;</li></ul>JavaSript, Assembler,WMLScript,C# , Visual Basic, OPL and so on…<br />By Parimal Patel,CSE dept.<br />
  43. 43. 4. Overall Evaluation<br />4.1 Advantages  <br /><ul><li>Operating system designed from scratch for mobile platforms
  44. 44. mobile phones are both small and mobile
  45. 45. mobile phones are ubiquitous – they target a mass-market of consumer, enterprise and professional users
  46. 46. mobile phones are occasionally connected – they can be used when connected to the wireless phone network, locally to other devices, or on their own
  47. 47. manufacturers need to differentiate their products in order to innovate and compete in a fast-evolving market
  48. 48. the platform has to be open to enable independent technology and software vendors to develop third-party applications, technologies and services
  49. 49. Best fitted for mobile market
  50. 50. Great market share</li></ul>By Parimal Patel,CSE dept.<br />
  51. 51. 4. Overall Evaluation<br />4.2 Limitations  <br /><ul><li>Steep learning curve for developers 
  52. 52. Developing in general  
  53. 53. Porting 
  54. 54. Symbian signed 
  55. 55. Dependency on Nokia (!)</li></ul>By Parimal Patel,CSE dept.<br />
  56. 56. 4. Overall Evaluation<br />4.3 Future possibilities <br /><ul><li>The leading mobile OS</li></ul> Symbian OS is still the “leading figure” in the smartphones market and according to Gartner Symbian’s market share is still the majority with a trend to decline.<br /><ul><li>Symbian - open source software platform</li></ul>  Nokia’s buying the rest of Symbian that it doesn’t already own, and will then create the Symbian Foundation, in collaboration with a number of other companies, and make Symbian royalty-free and open-source.<br /><ul><li>Implications to the other OS</li></ul>  The Symbian Foundation stirs up the future of the open mobile platform space. It does seem fair to draw the conclusion that the Symbian Foundation puts the Symbian platform in a stronger position and this will negatively affect the other players.<br />By Parimal Patel,CSE dept.<br />
  57. 57. 4. Overall Evaluation<br />4.3 Conclusion<br /><ul><li>Manufacturs point-of-view

  60. 60. Developers point-of-view
  61. 61. Developing for Symbian brings limitations.
  62. 62. A Symbian developer will only develop for Symbian. Is that interesting?</li></ul>By Parimal Patel,CSE dept.<br />
  63. 63. 4. Overall Evaluation<br />By Parimal Patel,CSE dept.<br />4.3 Conclusion<br /><ul><li>Symbian OS is a robust multi-tasking operating system, designed specifically for real-world wireless environments and the constraints of mobile phones (including limited amount of memory).
  64. 64. Symbian OS is natively IP-based, with fully integrated communications and messaging.
  65. 65. It supports all the leading industry standards that will be essential for this generation of data-enabled mobile phones. Symbian OS enables a large community of developers.
  66. 66. The open platform allows the installation of third party software to further enhance the platform.</li></li></ul><li>References<br /><ul><li>
