Study Notes
Software Requirements Analysis II: Class-Based Methods
- Requirements modeling strategies include structured analysis (data and processes separate) and object-oriented analysis (focuses on classes and collaborations).
- Class-based modeling represents objects manipulated by the system, operations (methods/services), relationships (hierarchical), and collaborations between classes.
- Elements of a class-based model include classes, objects, attributes, operations, CRC models, collaboration diagrams, and packages.
- Identifying analysis classes involves examining usage scenarios using a "grammatical parse" (underline nouns/noun phrases).
- Manifestations of analysis classes include external entities, things, occurrences/events, roles, organizational units, places, and structures.
- Potential classes are useful for analysis if information about them needs to be retained throughout the system's lifecycle and they must involve operations altering attributes.
- Attributes describe classes, and examples include playing statistics or pension fund information for baseball players.
- Operations (methods) are verbs in a processing narrative and are categorized into: manipulating data, computations, inquiring about object state, or monitoring for events.
- CRC modeling (Class-Responsibility-Collaborator) uses index cards to represent classes, responsibilities, and collaborators, aiding in system or product requirement organization.
- Analysis packages categorize elements like use cases and analysis classes for better organization and visibility, using plus/minus/hash symbols for access controls.
Behavioral Modeling
- The behavioral model details how software responds to external events, requiring analysis of use cases, identifying interaction sequences and events, creating sequences for use cases, building state diagrams, and reviewing accuracy and consistency.
- States in a system have characteristics (both passive and active), and state transitions occur based on events. Actions are the consequences of transitions.
- Steps for creating a behavioral model include listing states, noting transitions and events, and drawing state diagrams or sequence diagrams.
Interaction Model
- The interaction model is composed of use cases, sequence diagrams, state diagrams, and a user interface prototype. These diagram types are key UML notations.
Functional Model
- The functional model details the user-observable elements and internal operations of a WebApp, and can be represented using activity diagrams. Activity diagrams represent the flow of processing.
Reviewing the CRC Model
- CRC model participants should have separate collaborative cards and use cases should be grouped. Use-case scenarios should be used to review the responsibilities noted on model cards. Modifications to cards, or new class creation/revising of responsibilities may be necessary to fulfill identified needs.
Associations and Dependencies
- Analysis classes are often related in associations, which can be refined by specifying multiplicity (cardinality) relations.
- Client-server relationships often create dependency relationships from the client class to the server class.
Content Model
- Use cases are crucial for extracting content objects. Content object attributes and relationships are extracted, including hierarchy where applicable.
