Be sure to read the Project area of each Assignment section, as they talk directly to the milestone tasks. Also, for review purposes, note that typical milestone solutions will be posted on Wednesday morning of the following week. This is necessary as it is important.
Deliverables:
Activity Diagram
Potential Object List
System Sequence Diagram
Class Diagram
Candidate Matrix
Review all of the milestone project steps below. Post questions in the Milestone Virtual Lab Forum discussion area.
Milestone 7
Object-oriented analysis emphasizes the integration of processes and data. Like data and process modeling, object modeling is a technique for defining business requirements for a new system. But where traditional data modeling (ERDs) model just the static data and traditional process modeling (DFDs) model the processes of the system, object modeling integrates data and process concerns into constructs called objects.
The object modeling technique uses methodologies and diagramming notations that are completely different from the ones used for data and process modeling. These techniques are part of the Unified Modeling Language (UML). Object-oriented analysis techniques are best suited to projects that will implement systems using emerging object technologies. However, they can be used with any implementation technology.
In Milestone 3, we used use cases to model system requirements. Use case diagrams are one type of UML model. In this milestone, we will transform a use case narrative into an activity diagram that will graphically depict the process steps of the use case. We will also identify objects, their data attributes, and relationships that support the required business functionality and model them in an object class diagram.
Milestone 7 Instructions
For this milestone, you will be using the following templates/resources:
Activity Diagram – create using Visio or other drawing tool
Update Exhibit 7.1 – copy the chart into Word and update as required
Draw a class diagram – create using Visio or other drawing tool
Milestone 8
The purpose of the decision analysis phase is to identify candidate solutions, analyze those candidate solutions, and recommend a target system that will be designed and implemented. Alternative solutions to be considered should be those that address the business requirements of the information system.
In this milestone, you will complete a candidate matrix. This matrix will include three alternative candidate solutions that you have determined will meet the business requirements for the CTTS. Some of the solutions you will consider may have been posed from the design ideas and opinions from the system owners and users. Others may come from various sources, including systems analysts, system designers, technical consultants, and other information systems (IS) professionals. Some technical choices may be limited by a predefined, approved technology architecture provided by system managers. When completing the matrix, it is not your intent to evaluate the candidates at this point, only to identify and define them.
