Movie Rental System Analysis and Design

This assignment analyzes a movie rental system, focusing on its inefficiencies due to uncoordinated systems across different stores. The analysis involves creating Context Diagrams, Level 0 & 1 Data Flow Diagrams, and an Event Table to illustrate the proposed new information system. The report highlights the need for a centralized database for improved communication and information sharing among stores.

Requirements Analysis and Modelling 3
Introduction
System development is a systematic process that involves several phases. System analysis and
design are some of the key phases which play a key role in development of a system that meets
the clients’ requirements and industry standards. System analysis involves collecting and
assessing data, determining problems, and breaking down a system into components (Hoffer,
2012). It is key for businesses seeking to develop a system as it allows them to study the
proposed system and its components which helps them determine its goals. With system
analysis, businesses have an effective problem solving technique that enhances their system and
ensures all system components work as expected to achieve their purpose (Larman, 2012). On
the other hand, system design is a process that focuses on planning a new system or replacing a
system by giving a definition of the system modules with the purpose of satisfying particular
requirements (Dennis, 2015). Before embarking on planning a business system, a business has to
gain deeper insight into the old system and identify how computers can be leveraged in order to
ensure they operate efficiently. Through system design, a business can thoroughly understand a
system and focus on how to achieve the goals of the new system (Satzinger, 2011). System
analysis and design places an emphasis on systems, processes, and technology which are key
factors in system development.
The purpose of this work is to focus on investigating the problems encountered by Lilydale
Movies and recommend new solutions that could be incorporated when building a new
information system. Currently, the company has various problems that undermine its operations
and challenges its scalability. As such, the company management needs a new information
system could assist the company in scaling its operations and expanding its market. This work
will pay attention to the data aspects of the company and provide an optimal solution that the

Lilydale can adopt. To do this, data has to be completed in order to complete the assessment
process and complete the report. The case study will be leveraged to provide information about
the company including problems faced.
Company/Organization Background
Lilydale Movies is a movie sales and rental chain that sells and loans its movies to customers.
The company offers a wide selection of movies which has become its competitive advantage.
The company is niche-specific as it focuses on not only selling and loaning movies but also
providing extra services. Unlike major movie hire chains, Lilydale provides additional services
which include pickup and delivrery, assisting customers with their movie selections, and
providing an extensive movie selection for hire or sale from different parts of the country and
from the past. The company has five stores in Melbourne located in strategic places with high
customer traffic.
Key Business Problem
The major problem undermining the business is lack of connection between systems operated by
the company’s stores. Each store has its own system which assist in managing operations. The
system support various activities such as borrowing and selling movies, registering new
customers, managing membership, generating reports, managing catalogue of movies, among
others. These systems are not connected with each other hence cannot communicate or
coordinate operations between the stores. This implies that data generated in one store that may
be critical to other stores cannot be shared. With the number of stores owned by the company,
the system disconnection is a major drawback to the organizational operations. Currently, the
company needs to process more information and generated detailed reports. This cannot be
achieved with the current independent systems which run on their own databases. Consolidation

of the systems is a vital issue for the company as it seeks to expand in the market by introducing
new stores in different locations (Kirchmer, 2012). These stores needs to have a way to
communicate with each other to enhance operational efficiency and eliminate data redundancies.
Due to the disconnection, member’s information cannot be shared between stores. This creates
challenges especially when customer’s membership information is stored in one store and wants
to borrow or buy videos from another store. In such case, the staff have to call the store where a
member was registered to access the borrowing history.
The business has to focus on this problem as it undermines its operations. Without a consolidated
system, communication between the stores is constrained which can disrupt activities that rely in
shared data. Multiple systems incur a lot of costs and are barriers to scaling company operations
(Bocij, 2008). As a result, the company cannot achieve operational efficiency or effectively
expand its presence to different markets. By resolving this problem, the company stands to
benefit from enhanced communication between the stores and consolidation of systems. With a
consolidated system, Lilydale movies is well placed to improve customer service as data is
centrally located and customers can be efficiently served. Stores can easily communicate with
each other and coordinate in enhancing operational efficiency. Additionally, the company can
establish many stores while maintaining control over them.
Functional and non-functional requirements
The functional requirements for the new system include:
 Store data in a central database
 Allow multiple system connection to the database while maintaining database integrity
 Record movie sales and produce receipts

Requirements Analysis and Modelling 6
 Allow customers to reserve unavailable movies and send them an email once the movie is
available
 Generate relevant reports on a regular basis (rent analysis report, sales analysis report,
movie rentals report)
 Manage movie catalogue
 Allow customers to send comments about products they have bought or rented
 Allow parents to monitor items rented or purchased by their children
 Support inventory management
 Send requests for new movies for sale and rent
 Check due date for outstanding rentals and send notification to customers
The non-functional requirements for the system include:
 Handle expected and non-expected errors in a manner that prevents data loss.
 99.5% uptime
 System response and performance should be fast
 Inbuilt data validation mechanisms
 Handle large amount of database
 Support data sharing

The key processes involve customers, staff, and manager. The manager borrows movie and
receives a receipt. The staff member manage membership and movie catalogue while the
manager requests various reports.

Level 1 Diagram
Customers are involved in several processes which include borrowing/buying movie, returning
and reserving movie, comments on products purchased, and monitoring movies bought or
borrowed by children . The staff members manage the inventory and manage membership. On
the other hand, manager requests various reports related to store operations.

Conclusion
Based on the system analysis and design conducted on the company’s system, it was noted that
that lack of consolidation of systems was the main problem. Without coordinating the systems
used at different stores, there was little communication and information sharing which hampered
company operations. It is recommendable for the company to have one database which is
accessed by all the systems. This keep everyone updated about the activities of the other stores.
Data flow diagrams have been drawn indicating how the new information system will operate.
