Open source technology software

  1. 1. By Anandan. P Neelagandan. J
  2. 2. AbstractOpen Source Software (OSS) is software products available to the public, with its source code to study, change, and improves its design.However when open source used for commercial purpose, then an open source license is required.The quality assurance principle under open source software development is an approach to improve software product quality against traditional (or) new methods and techniques.Many industries and business sectors are following or using OSSD
  3. 3. Outline …IntroductionOpen Source SoftwareOSS free fromOSS Business ModelsList of Open Source SoftwareAdvantage and Disvantage of OSSConclusion
  4. 4. IntroductionOpen source is a model of software development that has been growing since the 1970s.Exactly like the personal computer and the Internet, open source software recently got the attention of the press as a totally new thing that ‘suddenly appeared’.Open source software is becoming the most interesting ‘new’ phenomenon of the entire information technology landscape, generating a level of interest similar to that of the First moments of the Internet.Open source software extended this idea by using the Internet to recruit a much larger population of volunteer developers.
  5. 5. Open Source SoftwareOpen-source software (OSS) is software which can be used, modified and improved by anyone and can be redistributed freely.
  6. 6. OSS free from The freedom to study and modify the software. The freedom to copy the software. The freedom to improve the software.
  7. 7. Open Source Business ModelsTraditional NewSupport Sellers Service EnablerLoss Leaders Brand Licensing Software FranchisingWidget Frosting Sell it, Free itAccessorizing
  8. 8. Traditional: support sellersCompanies that package together open Source software, and make their money from either selling a software and changing to service the software Red Hat is the leader in this industry
  9. 9. Traditional: Loss LeadersCompany that generally gives away software for free and makes money from selling additional software Example:  Adobe  Fedora
  10. 10. Traditional: Widget FrostingCompany that sells hardware and packages it together with open source softwareSilicon Graphics: Supports and shapes SambaVA Linux
  11. 11. Traditional: AccessorizingCompany that sells books, compatible hardware, t-shirts, bumper stickers, coffee mugs, dolls, etc. Example: O’Reilly sells more of the compatible hardware, manuals, software
  12. 12. New: Service EnablerCompany that distributes open source software primarily for generating revenue through on-line services  i.e. On-line gaming
  13. 13. New: Brand LicensingCompany that charges other companies for the right to use its brand names and trademarks in creating derivative products
  14. 14. New: Software FranchisingA combination of several of the other models in which a company authorizes others to use its brand names and trademarks in creating associated organizations doing custom software development and supplies franchises with training and related services in exchange for franchise fees of some sort
  15. 15. New: Sell it, Free itSoftware products start out their product life cycle as traditional commercial products and are converted to open source products when appropriate
  16. 16. List of Open Source Software: Firefox Feed Reader Open Office Thunderbird
  17. 17.  Advantage of OSS  Disvantage of OSS  Learning curve  Stability  Equivalent programs  Free Software  More technical ability  Runs on old hardware needed  Security  Not all hardware compatible
  18. 18. The current practical picture for OSS deployment Browser Desktop OS Email Content Management System Digital library services Integrated groupware Library catalogues Network services Office suite Payroll Scientific workstation Student records VLE & portal
  19. 19. ConclusionFree/open source software systems for government represent a significant opportunitySeek high-level, user-friendly processes for government operations expressed as open source, computationally enact able processes
