Shenyang abundance and Information Technology Center (www.4000010001.com) is specialized in the "software development, website design, development of micro-channel public number, 400 calls for the network to promote" business, the company adhering to the "honesty, hard service" concept To provide you with the highest quality products and services. Welcome to inquire! Contact: Lien Ze. A plan to solve the problem of the overall definition, including the understanding of user requirements and the reality of the environment, from the three aspects of technical, economic and social factors, feasibility studies and demonstration software development flow chart of the software project, the preparation of the feasibility study report explore solutions to the problem, and the resources available (such as computer hardware, system software, manpower, etc.) cost of software development professionals, to estimate the benefits and development progress can be made to develop an implementation plan to complete the development tasks. 2 analysis software requirements analysis is to develop a kind of software systems analysis and vision. It is a user needs to be Qucuqujing, discriminating, properly understood, then put it in software engineering development language (in the form of functional specification, ie, requirements specification) process expressed. The basic task of this phase is to determine and users together to solve the problem, create a logical model of software requirements specification document and write the final user acceptance. There are structural analysis methods, data flow diagrams and data dictionary main method and other methods of needs analysis. This phase of work is in accordance with the requirements of the requirements specification, design build architecture corresponding software systems, the entire system will break down into several sub-interfaces relations software development systems or modules, subsystems or modules is defined between the various subsystems Specifically designed to define, write software outline design and detailed design specification, database or data structure design specifications, assembly and testing program. In the initial stage of any software or system development must fully grasp the needs of users, in order to be able to follow the system development process, what features should be implemented, which taken specifications and restrictions set priority to positioning. Systems engineers will eventually be completed accordingly design, on this basis for subsequent program development, system functionality and performance descriptions and restrictions to define. 3, after finished the outline design, we have carried out a detailed description of its [1], for each function, including what little function setting them; so developers in the development process have a clear goal to development work to protect the rational allocation and management. 4. done after detailed functional design, our programmers and engineers can develop according to our detailed design document and in accordance with the software development code specifications coding.
