During design, the analyst: * Draws a model of the new system, using data flow diagrams (DFD) and entity-relationship (ER) diagrams. * Devises formats for all the reports that the system will generate. * Develops a method for collecting and/or inputting data. * Defines the detailed data requirements with a data dictionary. * Writes program specifications. * Specifies control techniques for the system's outputs, database, and inputs. * Identifies and orders any hardware or software that the system will need. By the end of the logical design phase, the analyst has prepared complete systems specifications in the form of a detailed report, with step-by-step instructions that describes the proposed system. Phase 5: Software Development The design specifications are converted into source code of a programming language. The programmers are responsible for carrying out activity. The software, which is to be developed, is divided in to many modules according to the sub-divisions in phase 3. The modules can be developed independently and then are to be tested individually. This type of testing is called unit testing. The test data are framed in such a manner as would ensure the entire modules can be tested. Phase 6: Testing Before actually implementing the new system into operation, developed system is to be test in order to remove all the bugs. ...read more.
