Life Cycle The system increase life cycle is the overall process of developing, implementing, and retiring data systems through a multistep process from initiation, analysis, design, implementation, and maintenance to disposal. There ar many different SDLC examples and methodologies, but each generally consists of a series of defined steps or phases. For any SDLC mildew that is used, information security must be integrated into the SDLC to catch appropriate protection for the information that the system will transmit, process, and store. 1.1Compare different lifecycle model System Analyst would suggest to use SSADM. There are some more system and designing development model available. Such as RAD, OOM, DSDM etc. There are so many reasons to select SSADM to develop this system. Unlike rapid use development, which conducts steps in parallel, SSADM builds each step on the break down that was prescribed in the previous step with no remainder from the model. Because of the...
