The purpose of this assignment is to review the IT Online Training Project Requirements and begin modeling the requirements by using the noun analysis technique to identify domain classes, attributes, operations, and requirements. You will analyze the case study, the IT Online Training Project, which will be used for your assignments throughout the course. You need to review the IT Online Training Project Requirements 2018R2 document and become familiar with it. Using the Analysis Specification Template 2018R4, you will fill in sections as the course progresses each week.

Initially, complete Section 1 of the template with information from the requirements document, and also complete Section 4.3, which involves creating a list of classes with their definitions, attributes, operations, and requirement numbers derived from the document. Use the noun analysis technique to discover potential classes by analyzing the text for nouns and noun phrases that can represent classes, as demonstrated in the provided examples and resources.

Identify and list all potential classes, starting from those already referenced in course resources, such as ScheduledCourse, SelfPacedCourse, Course, Product, Video, Book, UserAccount, Instructor, ExpertiseArea, Customer, etc., and discover additional classes from the requirements document. For each class, define it in the form "A [classname] is a ...", ensuring class names are nouns, singular, and capitalized. List attributes and operations (methods) for each class, such as get/set methods for attributes, considering the requirements and grading guidelines.

Document your findings in a table format with columns for class name, definition, attributes, operations, and requirement number. Arrange classes alphabetically for clarity. Include at least nine classes identified from existing resources plus those discovered through noun analysis. Discuss your list of classes and justify your choices, referencing the case study as appropriate.

Complete the required sections by including your class list, definitions, and justifications, submitting the Word document named appropriately, ensuring all sections of the template are filled as specified. Use credible references to support your analysis.

The analysis and modeling of software requirements are foundational steps in system development, especially in object-oriented design. For the IT Online Training Project, this process begins with identifying classes based on textual requirements, a technique known as noun analysis. This technique involves scanning the requirements document for nouns and noun phrases that suggest classes, attributes, or operations within the system. This approach streamlines the transition from textual requirements to conceptual models, ensuring that all relevant entities are considered in the system design.

Understanding the importance of class identification in the early phases of system analysis, it is essential to start with known classes provided by course resources, such as ScheduledCourse, SelfPacedCourse, Course, Product, Video, Book, UserAccount, Instructor, and ExpertiseArea. Each of these classes has predefined attributes and methods that can be inferred from the requirements. For instance, the Customer class (REQF2.1) might have attributes like customerId, firstName, lastName, address, workPhoneNumber, and cellPhoneNumber, along with operations such as create, delete, get, and set methods for each attribute.

However, the scope extends beyond these initial classes. Applying noun analysis to the requirements document reveals additional classes, such as Enrollment, Payment, Assessment, InstructorAssignment, Certificate, and Schedule, among others. Each class is defined to encapsulate a specific concept or entity within the system. For example, an Enrollment class might be defined as "A Enrollment is a record of a student's registration for a course," with attributes such as enrollmentId, studentId, courseId, enrollmentDate, and status, along with methods to create, update, or delete enrollments.

The process of defining these classes involves describing each in a consistent format, such as "A [ClassName] is a ...", ensuring clarity. Attributes typically start with lowercase letters and describe properties, while operations start with lowercase letters and describe actions on the class. For instance, getEnrollmentId(), setEnrollmentId(), or modifyStatus(). These methods facilitate the interaction with class instances and are crucial for later stages, such as class diagram design.

Organizing the classes alphabetically aids in clarity and systematic analysis. The comprehensive list created through this process forms the backbone of the system's conceptual model. Justifying each class involves referencing the requirements document, demonstrating how the class fulfills specific system needs or functionalities, and ensuring traceability from requirement to class.

In conclusion, the application of noun analysis in identifying classes for the IT Online Training Project bridges the gap between textual requirements and the eventual object-oriented design. It ensures that all entities are considered, appropriately defined, and ready for further modeling steps, such as creating class diagrams and detailed design specifications. This disciplined approach enhances the consistency, completeness, and traceability of the system development process.
