IT460–3: Create logical models that describe system processes. Assignment Instructions Avery has opened a gym and rehabilitation center specifically designed to provide training and recovery for service members who may have been injured while on duty. New members are provided a free fitness assessment to help determine their current fitness levels and to ascertain the extent of any injury to help onboard them into the program. Avery has designed a basic system to help onboard these new gym members. When members are seen for the first time, they complete a simple gym membership form that asks for their name, address, phone number, and brief medical history, which are stored in the gym member file.

They are also asked to schedule a Fitness Assessment. Therapists or trainers must check the assessment calendar file for an available time. Members may also call to change their assessments. Because these assessments are scheduled in advance, Avery usually sends a reminder postcard and text message to each member one week before the appointment. Assignment Requirements Use Visio to Construct a Level 1 DFD based on the attached use cases.

Each use case corresponds to a process in the Gym System. Use Gane and Sarson symbols. All the information can be analyzed from the Use Cases. Some of the Information is provided below. You will have to determine and label all the Data Flows in the DFD.

Check Gym Member name with Gym Member file. If new Gym Member, get address and phone number and enter in new Gym Member file entry. If this is a fitness assessment change, find current fitness assessment in fitness assessment file, and cancel it. Get desired fitness assessment time and match with available fitness assessments in Calendar File. When a suitable time is found, enter scheduled fitness assessment in the Calendar file and confirm with Gym Member.

Paper For Above instruction

The system managing new gym memberships and fitness assessments for Avery’s rehabilitation center requires a detailed logical data flow model to streamline processes and ensure effective communication among clients and staff. Building a Level 1 Data Flow Diagram (DFD) using the Gane and Sarson notation provides a clear visualization of how data travels through the system, highlighting key processes, data stores, data flows, and external entities involved. This analysis considers all documented use cases to accurately reflect the system’s operational structure, focusing on processes such as scheduling or altering fitness assessments, collecting new member information upon arrival, and sending reminder notifications to clients.

Introduction

The unique focus of Avery’s center is to support injured service members through a systematic approach that includes initial registration, assessment scheduling, and ongoing communication. The core processes involve capturing new members’ data, managing assessment appointments, and ensuring timely reminders. As such, the logical models must encapsulate these activities to ensure data integrity, operational efficiency, and customer satisfaction.

Analysis of System Components

The primary external entities include the Gym Member, who interacts with the system by providing personal and medical information, scheduling or rescheduling assessments, and receiving reminders. Internally, the system maintains several data files, notably the Gym Member File, which stores detailed profiles, and the Calendar File, which tracks available and scheduled fitness assessments. The processes operating within the system can be categorized as scheduled or on-demand activities, mostly revolving around appointment management and notifications.

Processes and Data Flows

The first key process involves the Gym Member making or changing an assessment. This requires retrieving or creating a member profile, checking existing assessments, and updating scheduling information accordingly. Data flows start with inputting the member’s name, which is verified against existing data; in case of new members, their registration details are collected and stored. When changes are made, the system searches for the current assessment, cancels or modifies it, and finds an available time slot in the Calendar File. Once scheduled, a confirmation is sent to the member.

The second process addresses the arrival of new gym members for assessments. When a new member arrives, they fill out a form with personal details, which then updates the member’s profile, including their medical history. This initial data collection ensures accurate records and engages the client in the ongoing assessment process.

The third process automates notifications — sending reminder postcards and text messages a week before scheduled assessments. Each day, the system reviews the Calendar File for any upcoming assessments and initiates communication with the respective members, ensuring they are reminded of their appointments, thus improving attendance and compliance.

Design of the DFD

The Level 1 DFD constructed using Gane and Sarson symbols clearly depicts the flow of data among these processes. It illustrates the external entity 'Gym Member' interacting with processes such as 'Schedule or Change Assessment', 'Collect Member Information', and 'Send Reminder Alerts'. Data stores include the 'Gym Member File' and 'Calendar File,' which hold persistent data essential for the processes. The data flows are mapped to indicate the movement of information, such as member names, assessment schedules, contact details, and notification messages. A minimum of 16 data flows are mapped to establish comprehensive coverage of the processes.

Conclusion

Creating a precise and detailed Level 1 DFD is crucial for understanding, designing, and optimizing the system supporting Avery’s rehabilitation center. The diagrams facilitate communication among stakeholders, improve system clarity, and serve as a foundation for further development. Properly capturing data flows related to membership management, assessment scheduling, and communication ensures that the system remains responsive, reliable, and capable of supporting the center’s mission to assist injured service members effectively.
