Software requirements analysis is to develop what kind of software is a systematic analysis and vision. It is a user needs to be Qucuqujing, discriminating, properly understood, then put it in software engineering language (in the form of functional specification, that requirements specification) process expressed. The basic task of this phase is to determine and users together to solve the problem of mobile phone software development, establishment of software logic model software development center, writing requirements specification document and final user acceptance. There are structural analysis methods, data flow diagrams and data dictionary methods main methods of needs analysis. Software design can be divided into the outline design and detailed design of the two phases. In fact the main task of the software design is to break down software into modules means to achieve a function of data and program instructions executable program units. May be a function, process, subroutines, separate program and data section with a description of the procedures can also be a combination, it can be dismantled and replaceable functional units. Software development module, then the module design. Outline design is the structural design, and its main objective is to give the software module structure PC software development, represented by the software structure. The primary task is to program the detailed design process design modules, algorithms and data structures, secondary task is to design a database, commonly used method is still structured programming methods.
