Personal Trainer, Inc. is planning to expand internationally by opening a supercenter in Toronto and has hired IT consultant Susan Park to develop the information system for this facility. Susan recommended an in-house team to create a design prototype using a relational database, focusing on data design, user interface design, and application architecture. The case study outlines various tasks such as explaining normalization, creating an ERD, and discussing system architecture, user-centered design, and marketing strategies for the new system.

1. Case study- assignment 6
For this module, you are required to complete the Case Study:
Personal Trainer, Inc. for Chapter 9.
Personal Trainer, Inc. owns and operates fitness centers in a
dozen Midwestern cities. The centers have done well, and the
company is planning an international expansion by opening a
new “supercenter” in the Toronto area. Personal Trainer’s
president, Cassia Umi, hired an IT consul-tant, Susan Park, to
help develop an information system for the new facility. During
the project, Susan will work closely with Gray Lewis, who will
manage the new operation.
Background
After evaluating various development strategies, Susan prepared
a system requirements document and submitted her
recommendations to Cassia Umi, Personal Trainer’s president.
During her pre-sentation, Susan discussed in-house development
and outsourcing options. She did not feel that a commercial
software package would meet Personal Trainer’s needs.Based on
her research, Susan felt it would be premature to select a
development strategy at this time. Instead, she recommended to
Cassia that an in-house team should develop a design proto-
type, using a relational database as a model. Susan said that the
prototype would have two main objectives: It would represent a
user-approved model of the new system, and it would identify
all systems entities and the relationships among them. Susan
explained that it would be better to design the basic system
first, and then address other issues, including Web
enhancements and im-plementation options. She proposed a
three-step plan: data design, user interface design, and ap-
plication architecture. She explained that systems analysts refer
to this as the systems design phase of a development

2. project.Cassia agreed with Susan’s recommendation, and asked
her to go forward with the plan
Tasks
1. In your discussion of the systems design phase, you
mentioned normalization to Cassia. She would like you to
explain the basics of normalization in plain English to help her
understand the data design tasks.
2. Review the Personal Trainer fact-finding summary in Chapter
4 and draw an ERD with cardinality notation. Assume that
system entities include members, classes, merchandise, and
fitness instructors.
3. Design tables in 3NF. As you create the database, include
various codes for at least three of the fields.
4. Use sample data to populate the fields for at least three
records in each table.
Case study- assignment 7
For this assignment, you will need to perform all of the tasks in
the Case Study: Personal Trainer, Inc. for Chapter 10.
Personal Trainer, Inc. owns and operates fitness centers in a
dozen Midwestern cities. The centers have done well, and the
company is planning an international expansion by opening a
new “supercenter” in the Toronto area. Personal Trainer’s
president, Cassia Umi, hired an IT consul-tant, Susan Park, to
help develop an information system for the new facility. During
the project, Susan will work closely with Gray Lewis, who will
manage the new operation.
Background
Susan and Gray finished their work on user interface, input, and

3. output design. They developed a user-centered design that
would be flexible and easy to learn. Now Susan turned her
attention to the architecture for the new system.Susan wanted to
consider their own organization and culture, enterprise resource
planning, total cost of ownership, scalability, Web integration,
legacy systems, processing methods, security issues, and
corporate portal. She also needed to select a network plan, or
topology, that would dic-tate the physical cabling and network
connections, or consider a wireless network. When all these
tasks were completed, she would submit a system design
specification for approval.
Tasks
1. What would be the advantages of selecting an Internet-based
architecture for the Personal Trainer’s system?
2. If Personal Trainer wants to increase its Internet marketing
efforts, what advice could you offer? Perform research to find
out more about the topic of Web-based marketing before you
answer Gray.
3. What software and hardware infrastructure will be necessary
to ensure Personal Trainer can process point of sale
transactions?
4. Prepare an outline for a system design specification and
describe the contents of each section.
