Design a system to track advance payments made to employees. Use uml diagrams and design patterns in this system. The design steps will be as follows.
Step 1 - Prepare an analysis document on the given topic.
Step 2 - Create a Use case diagram for your requirement that contains at least 3 actor, 10 use case and use all relationship type
Step 3 - Create an activity diagram for requirement
Step 4 - Create a class diagram for all requirement that contains at least 10 class, necessary relations and types. Add the important attributes of the classes to the model.
Step 5 - Use three design patterns, at least one creation, one structural, and one behavioral pattern, integrated into your classroom design.
Step 6 - Code one of the design patterns you use with java.
Note: The design should be homogenate. Excessive usage of any property type, object type, or function type is not suitable. For example, for creating 10 relations between classes, the number of relation types for aggregation,…

- Suppose you are working within the framework of the conceptual model in Figure Q4.5. FIGURE Q4.5 THE CONCEPTUAL MODEL FOR QUESTION 5arrow_forwardStakeholder Model In class, we discuss how to identify and analyse stakeholders. They are documented in a stakeholder model comprised of a stakeholder diagram and a stakeholder matrix. For this assignment, you will need to analyse the stakeholders for your 1st Assignment system. Please follow the guidance from the slides and literature to elaborate a model with all relevant stakeholders. It should be easy to identify at least 30 stakeholders and develop a hierarchy of at least four levels (onion model or sustainability model). The matrix may be split up into various tables, depending on what works best to represent the information you have collected. Consider the various domains stakeholders could be included from and what types of information you would need to make as good and as complete a requirements specification as you can.

You should use the 4 questions for the case study as a guide to the following: • Add new resort use case • Add book reservation use case • Activity diagrams • Sequence diagrams CRUD analysis. • Remember tables and diagrams always need a narrative to elaborate on them. This is what makes your document a narrative business document and not just a list of facts and ideas. Here is the case study.

- Use ER Assistant to draw your diagram. Draw a generalization hierarchy containing Employee, Administrator, and Faculty entities. The Employee entity is the supertype, and the Administrator and Faculty entities are the subtypes. The Employee entity has attributes as follows: EmpNo (primary key), EmpName, and EmpAddress. The Administrator entity has attributes as follows: AdmTitle, AdmContractLength The Faculty entity has attributes as follows: FacTenure, FacRank The generalization hierarchy should be disjoint but not complete.arrow_forwardGo me over the pros and cons of each model, and point out any additional or subtracted steps that might improve them in your opinion.arrow_forwardThe variables, Stress and Administrative Climate, in the questionnaire are abstract constructs that are measured using a multi-item reflective scale.
