Exceptions to the typical life cycle occur with non-recurring issues outside routine operations. For example, when a legal hold, litigation hold, or legal freeze is required, a records manager places a legal hold within the records management system, preventing the affected files from being scheduled for disposition.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

ISO/IEC/IEEE 12207 Systems and software engineering – Software life cycle processes [1] is an international standard for software lifecycle processes. First introduced in 1995, it aims to be a primary standard that defines all the processes required for developing and maintaining software systems, including the outcomes and/or activities of each process.
The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
Ontologies provide a set of defined terms and relationships between the terms to capture the information that describes the physical, functional, performance, and programmatic aspects of the system. Common ways for describing such ontologies are "Entity", "Relationship", and "Attribute" (ERA). ERA is often used to define database schemas.
The enterprise life cycle is a key concept in enterprise architecture (EA), enterprise engineering [2] and systems engineering. [3] The Enterprise Architecture process is closely related to similar processes, as program management cycle or systems development life cycle, and has similar properties to those found in the product life cycle.
