System analysis

System analytic thinking4.1 IntroductionSystem analysis is a major activity which takes place when we are structure a latest organization or changing one. abstract will help us to understand about the existing governing body and in any case will know the requirements necessary for the latest outline. And if there is no accessible system then system analysis will defines only the necessity.In system analysis the intimately important factor is to lay and right problems in system. A well understanding of the system will enables designer to understand and rectify the system problems.Existing SoftwareThe software is implemented in the system hard disc to the boniface. The server program runs constantly and waits for a connection to be recognized to it and will make available on line system to automate different operations completed in the network. 2.1.1 Existing SystemIn past the company staff uses the legacy system of carrying interoffice mails by the messengers from one substan ce ab drug user to other user of the company or they asshole also use the intercoms for c alone conference or even in somewhat cases emails are used for transmit of messages between the group community There are some disadvantages in existing system * Tedious message send system.* Communication is not instant.* Message transmit is done through insecure communication media.* Communication delays.* Maintaining the identities of all the members is not efficient. Like using manual of arms books, diaries, etc., for storing of users development.2.1.2 Proposed System To overcome the shortcomings of the conventional systems, the project aims at developing a multithreaded public messaging system for broadcasting messages to every member in the channel that allows multiple people (users) to interact with each other in a shared environment. The proposed system aims to fulfill the following Sharing of data in a real time environment, i.e., the data broadcasted can be edited online and vi ewed simultaneously. Providing fast, secure, reliable and cost effective broadcasting communication medium between community members. Support for public and private channels of communication. Multiple media transmission support like voice, text, images, etc. Personal peer messaging service. A user-friendly interface2.2 destiny AnalysisRequirement analysis provides software designer with a model of System culture post BehaviourModel can be translated to data, architectural, and component-level designs.2.2.1 Analysis Objectives Identification of the customers needs. Evaluation of the system for feasibility. Perform skilful analysis. Establish constraints. Create system definitions2.3 Software Requirements Analysis PhasesProblem recognitionThe existing system provides the information about products in the form of Local Advertisements media and paper advertisements. This is not sufficient to reach the end user properly. So, the company management is willing to maintain a web site which one accomplished all firm in detailed. Evaluation and synthesisAfter getting the clear problem definition we focused on what to do but not how to do. Ways to solve the problem and among the different ways we prepare and we selected the best way to solve the problem. ModelingWe made a rough diagram of the proposed system and showed it to the clients to depone whether their specifications are completely mentioned in that or not.SpecificationsThe software and hardware requirements and complete specifications are known. The running(a) and non functional requirements are known. ConstraintThe constraints are known and a clear definition of the system is given. ReviewA review of the whole process what we did and the result are shown to the clients.2.4. Feasibility Study Feasibility study is conducted at a time the problem is clearly understood. It is a high level capsule version of the entire System Analysis and Design process. The main objective is to determine how to solve a problem quickly, at a token(prenominal) expense and to check if the problem is worth solving. This system has been tested for feasibility in the following points functional Feasibility Technical Feasibility Economical Feasibility2.4.1 Economic Feasibility Economic feasibility is the most frequently used method for evaluating the effectiveness of the proposed system. During study costs are considered like costs of hardware, stripped-down configuration, system compatibility of H/W, etc., the proposed system minimizes the time effort of the data collection, answering queries and generating reports which results in significant saving. Thus, the proposed system is economically feasible. 2.4.2 Operational Feasibility Proposed projects are beneficial only if they can be turned into information systems that will meet the requirements. As current business methods are not acceptable to the users in call of speed, timely and accurate results, users welcomed a change that will bring about a more operational and useful system. With the rarely involvement it reduced the chances of resistance to the system and change in general and change magnitude the likelihood of the project successfully.2.4.3 Technical Feasibility It centers on the existing computer system and to what extent it can support the proposed system. The system can be expanded as the need arises. With the obtained technology there is guaranteed of accuracy, reliability, facility of access and security. Thus, it is technically feasible to design and develop the proposed system.3.
