METHODOLOGY OF SYSTEM DESIGNSoftware Development Life CycleThe SDLC adheres to significant phases that are needed for developers, such as planning, analysis, design, and implementation, and are explained in the section below. This process is used to model or provide a frame work for technical and non-technical activities to deliver a quality system which meets goals of the project.• PlanningPlanning the purpose of the phase is to find out the scope of the problem and determine solution. Resources cost benefits and other items should be considered during designed system• System analysis and requirementThe second phase which considers group of team work, the function require project or solution. It analyze the needs of users and ensure developed system meet the expectation of users.• System designThe third phase described in details the necessary specifications feature and operations that will satisfy the functional requirement of the proposed system which will be in place.
The flow of data processing is developed into charts, and the project team determines the most logical design and structure for data flow and storage. For the user interface, the project team designs mock-up screen layouts that the developer uses to write the code for the actual interface.• Development of systemNow the real work begins with developmental phase, marks the end of the initial section of the process. The developers design the database, generate the code for the data flow process and design the actual user interface screens. During the construction phase, test data is prepared and processed as many times as necessary to refine the code.• Integration/ TestingDuring the test phase, all aspects of the system are tested for functionality and performance. The system is tested for integration with other products as well as any previous types with which it needs to be transfer.
Basically, the key basics of the testing phase are to verify that the system contains all the end user requirements laid out in the analysis phase, that all the functions are accurately processing data, that the new system works with all other systems or prior systems, and that the new system meets the quality standards of the company.• Operations and maintenanceThis phase gets feedback from clients, and the code is tweaked for any performance issues or the mishandling of data. A training should be given to the users and how to maintain the system.
CONCEPTUAL OF DESIGN SYSTEMThis section describe more about the architecture, modules, interface, and data for a system to satisfy our requirements. We designed systems which could be seen as application of systems identifying short form and code words, suspicious messages that are hidden in images are sent among users via social media application.Conceptual modelFirstly: develop a framework features, detect text and image that contains suspicious word in short form and code word. This process dynamically filtering data structured/stored in database and identifies suspicious word are sent among users with the help of ontology, data mining and text mining techniques.Secondly: detecting suspicious messages in form of short and code words that users have sent post images or messages via social media.
Thirdly: block the spam details and blacklist them from sent image/text suspicious messages via social media.Architectural designThe architectural design of a system highlights a framework features, plan of the framework structure, performance and more perspectives of that system analysis.Overview systemIn this section, it talk about social media monitoring and scanning dynamically channels for information path through networking server tracking social media content such as images, video text that users sharing web application. A framework suggested monitoring users conversation via web application by watching, reading, listening and adding the reporting content of media source on continuing basis or identifying suspicious words by analysis content that contains specific keywords or documents in stream.Figure 1: Social media monitoring tools
