#ACTIVITY DIAGRAM FOR INTRANET CHATTING SYSTEM SOFTWARE#
Software design and its engineering is crucial for the scientific software impact. Moreover, we have successfully applied our approach in the design and engineering of different well applied and published Bioinformatics and Neuroinformatics tools including DroLIGHT, LS-MIDA, Isotopo, Ant-App-DB, GenomeVX and Lipid-Pro. We validated the approach by comparing old and new bioinformatics software solutions. The focus of research was to address following three key points: 1) differences and different challenges required to change from traditional to scientific software engineering, 2) scientific software solution development needs feedback and control loops following basic engineering principles for implementation and 3) software design with new approach which helps in developing and implementing a comprehensive scientific software solution. We propose a new approach ‘Butterfly’, for the betterment of modeling of scientific software solutions by targeting key developmental points: intuitive, graphical user interface design, stable methodical implementation and comprehensive output presentation. Software design and its engineering is essential for bioinformatics software impact. Below is the list of actions to be performed by the. Can close & open the picture window The following illustration shown in Fig 1 is the snapshot of manually designed Use Case diagram of HCI chat application. Also see the other connected user’s uploaded picture 9. jpg picture, which all the connected users can view 8. Read the responses coming from other users 7. Send message to a particular selected user as well as can broadcast the 5. From above discussed specified requirements here are some listed finalized functional requirements for HCI Chat application. Application should be flexible enough so then in future of some changes are needed then can be performed easily without interrupting already implemented stuff.Application should be very simple and interactive.o Log off when he wants o Quit the application. If user doesn’t want to see or have picture window then an option is to be provided to close that window. o Picture window should be like optional, I.e. o See the picture of selected user in picture window. o Attach or upload picture (any) of jpeg format which will be visible to all the connected users. o Receive and read the responses coming from the other connected users.
o Write messages o Send that messages to other users o Select one user individually or all the users at a time to send or broadcast the messages to all the connected users. Login user can o View already online/connected users.There should be a logging process (user login and logoff.According to the user’s requirements, we have to implement a chat application for two more than two user text based communication consisting of some basic but main requirements. Case study consists of a process including requirements, finalized requirements, use cases, conceptual class diagrams, class descriptions, physical sketch, identification of GUI design patterns and implemented user interface. CASE STUDY In this case study we try to limit the software engineering specific issues and we have concentrated on general issues of any interactive system by keeping a general reader in our mind set but some software design specific information is included as a part of our case study especially the sections followed by Class Descriptions, any non software engineer can skip that section as a part of his reading.
