The Unified Modeling Language ( Uml )

“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”

A profile allows UML to be extended for use with a particular programming platform or to model systems intended for use in a particular domain. A profile extends the UML to allow user-defined stereotypes, meta-attributes, and constraints.

In the object-oriented modelling class diagrams are very important. In data modelling techniques class diagrams are used. These class diagrams are represented by using the box symbol.

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

The above Flowchart is hard work and time consuming for a programmer that wanted to do the job as fast as possible. He would rather write a Pseudocode model. This Flowchart concept is best practice if the programmer wants to do presentation and demonstration of the way his/her program will flow.

The wolf-moose relationship will first be modeled using UML. The purpose and requirements of the conceptual model will be captured using UML via use case diagrams. Furthermore, a class diagram will be used to document the system components, and a state diagram will be used to capture the possible states of a wolf and moose. The state diagram may also be used as a building block for possible Markov Chain and Bayesian Net models. Sequence and Activity diagrams will also be generated to model the dynamic behavior of the predator-prey relationship. This model will be particularly useful for building a dynamic model.

Having being told to focus my attention on other colleges has yet to cross my mind until as of late. The reason UMSL was a number one choice for me was simply their ranking of their criminal justice program. What is now being realized is that their rankings on other standards are not up to par. According to the Niche’s 2018 best colleges, the University of Missouri St. Louis is ranked number 216 out of 666 public universities in America (Niche). This ranking is based on the following, academics, diversity, athletics, party scene, and so on. What needs to be included is campus safety and security. As of late, UMSL’s campus standards have dissipated. That's what the following will be specifying on.

By the time I managed to swallow the lump in my throat, I still hadn't come up with a good answer. The job description had emphasized the non-importance of prior recreation experience, yet admitting to my lack of previous exposure seemed a sure way to lose. So, with a quavering voice, I forced out a lame response about having to work at Modell's as a cashier. My interviewer responded only with a terse nod, and I guessed two things right away. One, that my answer didn't hit the mark. And two, that I probably wouldn't be getting the job.

Logical and physical models represent the key elements and processes of the software development. The logical model describes the processes, and data, in as much detail as possible, without giving regard to how the system will be implemented. Logical data models include

An explanation of the distinction between systems analysis and systems design and a description of the activities involved in each

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
