During system development, the members interact with users so that they can improve the system.

Some of the risks involved in a system request include reduced quality of the system (quality assurance), change implementation risks, requirement change feasibility and incorrect system requirements (Forouzan, 2007).
Choosing the appropriate UML modelling tool ensures the success of a software system and it’s very important to have the right criteria. Therefore, on what criteria should one select a UML modelling tool?
The choice of criteria is entirely reliant on the user’s requirements in terms of system support. A few requirements that have to be considered include:-
a. Code generation and model simulation tools
b. UML specification compliance support tools
c. Properties customization tools
d. UML semantics and notation support tools and
e. Inter-modelling UML tools (Forouzan,2007)
How can one determine the actors in a Use Case Study Diagram (UCD)?
The simplest way to do this is to determine the tasks performed by every actor. By doing so, actors are chosen in such a way that their behavior remains constant. In many cases, actors are comprised of humans, but in other cases, they consist of other systems as one’s system can interact with other systems such as a database system. In such an instance, choosing actors will based on their ability to function in such an interconnected system (Kizza, 2014).
Many users oftenly want to use different UML models in between modeling tools. How come it is not easy to apply multiple models of UML between tools of modelling?
The reasons are technical in nature and one of them is the fact that XML attempts to solve tasks that are more complicated than simply exchanging the models of UML. In most instances, a mechanism is usually provided that ensures the language exchange that is structured by the MOF (Met model Object Facility) (Kaminow, 2013).
The other reason is that the model does not have the required information to ensure a reliable communication network exchange among the modeling tools (White, 2012).

...Part Discussion I found this picture very nice, with some very fine details, but some flaws as well. First of all, the picture clearly seems to be from the early 20th century because of many reasons including the old hairstyles of the characters, turkey being served in the dish, and family gathering on the dining table placed inside the home. Today, hairstyles look much different with boys keeping spikes and women having shoulder-length hair and keeping them open.

Moreover, today cooking is not reserved for women only; all family members participate and enjoy doing the activity when it comes to special occasions. One...

Similarly, they can also come in handy when comparing health inequalities that may exist within populations, identify any areas that may require priorities in terms of health care delivery, carrying our research and development and examining the benefits likely to come about as a result of the healthcare interventions implemented (In Kirch, 2008). Summary measures should be comprehensible and practicable to calculate, and...
