Paper For Above instruction

The assignment involves developing a comprehensive use case and corresponding UML diagrams for two distinct scenarios: receiving a new book in a university library system and managing patient information entry, as well as extending a class diagram for a customer survey system and analyzing system capabilities for a jewelry company. This paper will systematically analyze and design these systems, delineating their processes, class structures, and development considerations.

Part 1: University Library System - Receiving a New Book

The process for receiving a new book within the university library system begins with the library staff logging the arrival of new materials. The staff scans or manually enters details such as ISBN, title, author, publisher, and acquisition date into the system. Once inputted, the system verifies whether the book already exists in the catalog; if it does, the system updates its inventory count, otherwise, it creates a new record for the book and its associated data. Post- entry, the system may generate a notification or confirmation to acknowledge successful receipt. This process ensures that the library's database remains current, facilitating accurate tracking and management of its inventory.

The UML activity diagram for this process would depict activities such as start, input book details, verify existence, update inventory or create new record, and end. Decision nodes would illustrate whether the book already exists in the system or not, guiding the workflow accordingly.

The sequence diagram, at a first-cut level, involves actor (librarian) interacting with domain classes such as Book and Inventory. The librarian initiates the 'Receive New Book' use case, sends a message to create or update a Book object, which in turn interacts with the Inventory class to update stock count. The diagram is minimalistic, emphasizing the core interactions necessary for processing a new book receipt.

The design class diagram would include classes such as Book, Inventory, and possibly Publisher and Author. A controller class, such as BookInventoryController, manages the interaction flow. View classes might include BookEntryForm, while data access classes could be BookDAO and InventoryDAO. These classes are positioned to separate concerns—handling user interface, business logic, and database access respectively.

Designing with CRC (Class-Responsibility-Collaboration) cards focuses on identifying classes, their responsibilities, and collaborations, facilitating early conceptualization and team collaboration. Conversely, sequence diagrams specify the interactions over time, detailing message exchanges between objects during a use case. CRC is more abstract, emphasizing responsibilities, while sequence diagrams depict actual interaction sequences.

In sequence diagrams, messages are the communication exchanges between classes or objects, represented by arrows. The syntax includes the message name, optional parameters within parentheses, and sometimes a return type. For example, a message might read 'updateInventory(count)', indicating a method call with a parameter.

The first-cut sequence diagram provides an initial, simplified view of object interactions necessary to accomplish a use case. Its purpose is to define essential actors and classes involved, establish communication flow, and serve as a foundation for further detailed modeling. Typically, it includes actor objects, domain objects, and primary messages, omitting detailed logic or auxiliary classes at this stage.

Part 2: RMO Customer Survey System Enhancement

Based on the textbook case, RMO plans to ask customers about competitor purchases in exchange for a discount, prompting the addition of Competitor and ProductCategory classes. The Competitor class has a single attribute, Name, and a one-to-many association with ProductCategory, which includes attributes like Description, DollarAmountPurchased, MonthPurchased, and YearPurchased. The existing Customer class also maintains a one-to-many relationship with ProductCategory. The class diagram revision involves adding these entities and their associations.

Revising the relational database schema entails creating new tables: 'Competitor' with a primary key for Name, and 'ProductCategory' with foreign keys referencing 'Competitor' and 'Customer' tables, along with the specified attributes. Ensuring tables are in 3NF involves eliminating transitive dependencies and redundant data, which optimizes data integrity and query performance.

Part 3: Developing the Jewelry Company System

The proposed jewelry company's sales and accounting system must track every sale, link to inventory for cost data, and generate daily profit and loss reports. Customer purchase histories are vital to facilitate targeted marketing and loyalty programs. Managing credit balances and aging accounts receivable with detailed reports and notices will improve cash flow and reduce bad debt.

System capabilities include sale tracking, inventory linkage, sales reporting, customer purchase history, credit management, and accounts receivable analysis. The development process should adopt an object-oriented approach, utilizing UML modeling to define class structures, process workflows, and user interactions. Integration with existing inventory and accounting modules, compliance with data security standards, and scalable architecture should be prioritized.

The project can be structured in phases—initial requirements analysis, UML modeling, database design, system development, testing, and deployment. Using Agile methodologies ensures customer feedback incorporation, enabling iterative refinement. Emphasizing modular design enhances maintainability, while robust reporting features support management decision-making. Training staff and providing user documentation are critical to ensure successful adoption.

In conclusion, systematically analyzing each solution domain with UML diagrams and clear design principles ensures that the university library, RMO survey enhancements, and jewelry sales systems meet organizational needs efficiently. Emphasizing data integrity, system usability, and scalability will facilitate successful implementation and support business growth.
