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_forwardUsing a diagram, explain the prototype model. What are the benefits, drawbacks, and applications of this model?arrow_forwardDevelop an activity diagram based on the following narrative. Note any ambiguities or questions that you have as you develop the model. If you need to make assumptions, also note them. The shipping department receives all shipments on outstanding purchase orders. When the clerk in the shipping department receives a shipment, he or she finds the outstanding purchase order for those items. The clerk then sends multiple copies of the shipment packing slip. One copy goes to purchasing, and the department updates its records to indicate that the purchase order has been fulfilled. Another copy goes to accounting so that a payment can be made. A third copy goes to the requesting in- house customer so that he or she can receive the shipment. Once payment is made, the accounting department sends a notification to purchasing. Once the customer receives and accepts the goods, he or she sends notification to purchasing. When purchasing receives these other verifications, it closes the purchase…arrow_forward
- Stakeholder 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. Everybody who can provide you with knowledge beneficial for the system, and therefore your requirements specification, should be represented in your…arrow_forwardHow does an entity-relationship diagram work and what precisely is it?arrow_forwardIn this question, step 4 of the question given below is asked.

- When evaluating descriptive models, what features and characteristics should you prioritize?arrow_forwardPerform the following activities as part of the assignment • Read the case study at the end of Chapter 5, (which I will include below). 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. The Spring Breaks 'R' Us Travel Service The SBRU information system includes four subsys- they only plan to provide some design specifications and tems: Resort relations, Student booking, Accounting guidelines to each resort. The resort will be responsible and finance, and Social networking. The first three for connecting to the Internet and for providing a secur are purely Web applications, so access to those occurs wireless environment for the students.…arrow_forwardUse 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_forward
