2. Operational Concepts Recent years, huge number of growth in Internet users and broadband usage File-sharing become extremely popular Emails, IM, Peer-to-Peer Apps Limitations in current file-sharing applications

3. Operational Concepts (cont.) EasyShare provides convenient way of sharing files Share files with friends, family, others Centralized database, eliminating peer-to-peer connection Faster than peer-to-peer file sharing Speed is only limited by the user’s own connection speed

4. System Requirements Users given fixed amount of storage Users can upload/download files to/from personal online database Folders can be made private, password protected or public Users can add friends, view/download their friends’ public files

5. System Requirements (cont.) Search files and download Protected folders are useful for sharing confidential files between friends Application maintains statistics for each file

6. System & Software Architecture Clients use application via window that includes friend management, download/upload/search files Server needs a database system Major software components include: login, main, friend management, down/upload window

7. System & Software Architecture (cont.)

8. Life Cycle Plan Seven weeks to complete with 4-8 students Requires developers knowledgeable in database, networking, and building platform Work divided into three parts Each developer spends ~15 hours/week

9. Life Cycle Plan (cont.) Use of Spiral Model Week 1: collect requirements, resources and build a detail design. Week 2 – 5: coding. Update the design if necessary. First release after week 2. Week 6: testing. Update the design. Second release at the beginning of the week. Week 7: testing and finish. Final release.

10. Feasibility Rationale Risks: Availability of developers with database & networking knowledge Security and high transfer rate Searching & sorting implementation

11. Feasibility Rationale (cont.) Can this really be built? With today’s resources and technology, YES, given that project members are knowledgeable in networking, database management, and platform building
