The system development life cycle is the overall process of developing, implementing and retiring information systems through a multi-step process from initiation, analysis, design, implementation and maintenance to disposal. There many different SDLC models and methodologies, but each generally consists of a series of defined steps or phases. # Feasibility Study # Requirement Analysis # Designing # Programming # Testing # Debugging # Implementation # Review and Maintenance Sometimes the waterfall model is also considered as the traditional system development life cycle.

The information system lifecycle focuses on the entire system development process, including planning, analysis, design, implementation, and maintenance. The database system development lifecycle is a subset of this, specifically focusing on the database design, implementation, and maintenance within the broader information system context. Both lifecycles work together to ensure that the database system supports the overall information system requirements and objectives.
The relationship between the information system life cycle and the database system development life cycle is that the informational systems help management entities to shift and move resources from one department to another easily by using a shared database system.
An administrator in SDLC, or System Development LifeCycle, implements the system, which can include installation and updating the system. One role of the administrator is to do maintenance activities that include preventative, corrective, and adaptive maintenance.
"This integrated approach to product delivery, allows for significant cost savings due to the collaboration between the workflows of each stage in the development lifecycle."
During system design development and sustainment efforts, Integrated Product Support Elements such as support equipment, technical data, manpower and personnel, training and training support, and facilities are considered. These elements are essential for ensuring that the system can be effectively operated and maintained throughout its lifecycle.
Being at the earliest point in the lifecycle, if wrong, it will have the longest running/biggest impact of wasting time on useless or off-the-mark work. You want correct input to each phase of the life cycle (or iteration of development). Defects should be found as early as possible to minimize the extent of rework necessary. Rework costs time and money which could runout. In the extreme, lack of resources or time will prevent any manner of successful completion.
