Every single stage of the software development life cycle creates products that are needed by the adjacent stage of this cycle. The several phases of the software development life cycle include a perquisite collection or accumulation and examination, under which the commercial necessities are collected. This particular stage is the supreme center of emphasis for all those who deal and directs the plan as well as the ones holding shares.

The next stage of the software development life cycle is related to the construction of the structure and the programs, which are created according to the necessities and the already mentioned details. It prepares the information and material that might be required for the upcoming stage of this cycle.

Furthermore, on getting the files and information on the classification, the functioning is shared out into the units of measurement and this is when the basic process of a systematically arranged and comprehensive collection of laws takes place. This is considered as the most extended stage of the software development life cycle.

After producing the comprehensive collection of laws, it undergoes a trial while comparing all the demands and needs in order to assure that the product is properly fulfilling the requirements. Therefore, having a favorable outcome allows the item to be dispatched to the client.

What is UML? What is an event in UML?

UML is based on machine diagrams, describing how the system works. Basically, UML diagrams are based on behavior and state. There are objects that are responsible of some simple processes and objects that would conduct things that are more complicated. Developers might have difficulties in understanding those concepts, and this is why the particularities of the systems must be established.

The states and behaviors of UML might be described with the help of those objects. All the actions of UML can be represented with simple of complex diagrams. A state is the first stage of the pattern, which determines the behavior of an object. In the fist stage, the object is created, and the final stage is considered the one in which there are no transitions left. This type of method used to represent the behavior of programming objects has been called UML.

The circles of diagrams represent the initial state as a closed circle, and in the final state, the object is represented as a bordered circle. Inside the borders, all the transitions of the object are represented using specific figures. This type of representation is great to understand the evolution of objects for programming, being the perquisite of artificial intelligence learning.
