In software engineering, the software development lifecycle is the process of dividing the software development effort into smaller, parallel or continuous steps or sub-processes to improve design, product management. This approach may include predefined specific deliverables and artifacts that the project team creates and completes for the development or maintenance of the software applications.

MVC (known as Model-View-Controller) is a pattern in software design that is commonly used to implement user interfaces, data, and control logic. It emphasizes the separation between the business logic and presentation of the software. This “separation of concerns” provides better division of labor and better maintenance.

Risk management is a system for identifying, addressing and eliminating issues that may be detrimental to the cost, schedule or technical success of a project or to the morale of the project team. “Tomorrow’s problems are today’s risks.” Therefore, “risk” is clearly defined as a problem that could cause some damage or threaten the project schedule, but has not yet occurred.

Hexagonal architecture diagram is an architectural pattern used in software design aiming at creating loosely coupled application components. This approach is an alternative to the traditional layered architecture. It is one of the many forms of DDD (Domain Driven Design Architecture).

One of the effective way to solve a complex problem is to break it down into simpler sub-problems. You start by breaking down the whole task into simpler parts. Step-by-step refinement is essentially a decomposition of the system to gain insight into the subsystems that make up the system, known as the top-down decomposition method.

The context diagram shows the system considered as a single high-level process, and then shows the relationship of the system to other external entities (systems, organizational groups, external data stores, and so on). Another name for a context diagram is a context-level data flow graph or 0-level DFD.

Software engineering focuses on the development of software products. it is a systematic, disciplined, and quantifiable approach to software development, operation, and maintenance; That is, engineering to software applications.

UML State machine diagram and activity diagram are both behavioral diagrams but have different emphases. Activity diagram is flow of functions without trigger (event) mechanism, state machine is consist of triggered states.

A flowchart is used to show the successive steps in a process. Such diagrams use a series of interrelated symbols to map the entire process, making the process easy to understand and helpful in communicating with others. Flowcharts can be used to explain the workings of a complex and/or abstract process, system, concept or algorithm. Flowcharting can also help to plan and develop processes, or improve existing processes.

A flowchart is a graphical representation of an algorithm, workflow, or process, with different types of boxes representing different types of steps, and arrows connecting every two steps. This representation facilitates the illustration of solutions to known problems. Flowcharts are widely used to analyze, design, document, and operate processes or procedures in many fields.
