BCIS 5307 – Final Exam Saving Instructions: Save the Final Exam Document using the following naming convention: CourseNumber_LastNameFirstInitial-FinalExam (i.e., 5307-SharpJ-FinalExam) MindPlay Educational Toys is a regional, California based company that currently has stores in Los Angeles, San Francisco, and San Diego. The company produces their own line of educational toys and also sells other toys from other companies in their three stores. MindPlay’s main customer base consists of parents and children interested in play that encourages learning. MindPlay has also recently created loyalty programs with teachers in the three cities and is actively looking for ways to foster relationships with local school districts and other learning institutions such as museums and zoos.
The loyalty program is very basic and consists of a mailing list gathered from in-store information request cards. The CEO believes that there are many more marketing opportunities available but is not sure how to go about increasing their customer base beyond the three stores. The production process for MindPlay and purchasing for all three stores is done out of the central office in San Diego. The production manager is responsible for soliciting bids for raw materials that are then shipped to a production facility in Fresno. The manager has had trouble managing production over the last few years as the economy in California has changed so quickly and predicting sales on the limited information available has become difficult.
During some fiscal quarters, some stores have too much inventory of MindPlay’s products while other quarters, some stores are falling short of various games and toys. Adding to the manager’s difficulties is the oversight of ordering other products from other educational game and toy suppliers. The manager orders games and toys from sixteen different suppliers throughout the year for all three stores. Currently, the inventory is managed at the central warehouse, and the manager ships the same number of each product to each store at the beginning of every quarter. Because the inventory is controlled centrally, it is difficult to determine what inventory each store has on hand at any given moment.
Most of the inventory reconciliation happens quarterly and requires managers at each store to manually take inventory at the conclusion of each quarter. As a result, the manager has noticed increased inventory loss and he also suspects that he is not managing the products in the most efficient manner. He would like a better idea of what product each store has on hand at any time and would like insight in how to better order products and materials for the production and inventory processes. Currently, there is little communication between stores and the technology at both the stores and the central office is becoming outdated. Most communication with vendors and suppliers is occurring through email and purchase orders are being processed manually.
The only connections currently between the locations are via Internet connections provided by a local ISP in each city. MindPlay’s CEO knows that they need to invest in infrastructure to solve some of the problems with the marketing, inventory and processing problems but is also interested in additional technology solutions. The CEO is interested in not only moving their inventory online, but she is also interested in opening stores in Chicago and Dallas. She believes the growing pains her company is already experiencing will be exacerbated by growth outside her region. Based upon the narrative provided above complete the following deliverables using appropriate systems analysis and design tools and techniques.

BCIS 5307 – Final Exam Assignment
Question 1: High-Level Data Flow Diagram
Data Flow Diagram (DFD)
In order to design a Data Flow Diagram (DFD) for MindPlay’s proposed system, it is essential to identify the external agents, processes, data stores, and data flows.
1. External Agents:
- Customers
- Suppliers
- Store Managers
- Central Office Staff
- School Districts and Educational Institutions
2. Processes:
- Order Processing
- Inventory Management
- Supplier Management
- Sales Tracking
- Marketing Management
- Customer Feedback Collection
3. Data Stores:
- Customer Database
- Inventory Database
- Supplier Database
- Sales Database
4. Data Flows:
- Orders from Customers to the Order Processing system
- Inventory requests from Store Managers to Inventory Management
- Inventory updates to Inventory Database
- Supplier communications for procurement
- Sales data from Point of Sale (POS) to Sales Database
- Marketing data sent to School Districts
Description: The DFD has been designed to highlight the flow of information between various components of MindPlay’s system while emphasizing the need for enhanced communication between stores and external agents. The arrows illustrate the flow of data, and the connecting lines present how each process interacts with another (De Marco, 2018; Satzinger, Jackson, & Burd, 2016).

Question 2: High-Level Activity Diagram with Swimlanes
Activity Diagram
The high-level Activity Diagram below outlines the activities involved in MindPlay's new system organized into swimlanes:
1. Customer Lane:
- Browse Products
- Place Order
- Provide Feedback
2. Store Manager Lane:
- Receive Inventory
- Update Stock Levels
- Generate Sales Reports
3. Central Office Lane:
- Process Orders
- Manage Supplier Relations
- Update Inventory Database
- Plan Marketing Strategies
Description: The swimlanes allow for a clear understanding of which processes are undertaken by each actor in the system— customers, store managers, and central office personnel. This visualization aids in establishing accountability and defines the roles played within the organization’s processes (UML, 2019; Larman & Basili, 2003).

Question 3: Relevant Issues Related to Storing and Tracking Inventory
- Inefficient inventory management leads to overstock and stockouts.
- Lack of real-time visibility into inventory across multiple store locations.
- Manual reconciliation processes increase risks of errors and inventory loss.
- Limited communication channels among store staff and central office, leading to delays in processing orders.
- Difficulty in accurately predicting sales due to inadequate data.
- No systematic approach to track supplier performance and delivery schedules.
- Absence of a unified dashboard for sales, inventory levels, and customer interactions.
These issues hinder the efficiency of MindPlay’s operations and can lead to loss of sales and diminished customer satisfaction (Boyes et al., 2017; Gitlow, 2017).

Question 4: Information Required for the Relational Database Management System (DBMS)
To manage inventory effectively, MindPlay would need to store the following types of information in a relational database:
1. Product Information:
- Product ID
- Product Name
- Description
- Quantity on Hand
- Reorder Level
- Supplier Information
2. Supplier Information:
- Supplier ID
- Supplier Name
- Contact Information
- Delivery Times
- Performance Metrics
3. Sales Transactions:
- Transaction ID
- Product ID
- Customer ID
- Date of Sale
- Quantity Sold
- Sales Channel
4. Customer Information:
- Customer ID
- Name
- Contact Information
- Purchase History
5. Store Locations:
- Store ID
- Store Name
- Location
- Manager Info
Discussion: Storing this information in a centralized database would alleviate many of MindPlay’s inventory-related issues by facilitating real-time tracking and access to data, ensuring better order processing, minimizing manual errors, and improving overall operational efficiency (Tamm et al., 2018; Chaffey, 2019).

Question 5: Major Entities Needed in Inventory Management
1. Product:
- Attributes: Product ID (PK), Name, Description, Quantity on Hand, Reorder Level
- Represents the educational items available in inventory.
2. Supplier:
- Attributes: Supplier ID (PK), Name, Contact Info, Performance Metrics
- Holds information regarding the vendors providing products.
3. Customer:
- Attributes: Customer ID (PK), Name, Contact Info, Purchase History
- Contains details of customers to manage loyalty programs.
4. Store:
- Attributes: Store ID (PK), Name, Location, Manager Info
- Represents different store locations and their management.
5. Sales:
- Attributes: Transaction ID (PK), Product ID (FK), Customer ID (FK), Date, Quantity Sold
- Tracks sales-related data connected to products and customers.
Discussion: Each entity is linked through relationships, such that a sale captures the transaction details between customers and products while correlating with store recorded data. These relationships ensure better data integrity and operational cohesion within MindPlay (Blumenberg, 2020; Rob, 2021).
---
Question 6: Entity Relationship Diagram (ERD)
Logical Design ERD
An ERD detailing the logical structure would show:
- Entities:
- Product (PK: Product ID)
- Supplier (PK: Supplier ID)
- Customer (PK: Customer ID)
- Store (PK: Store ID)
- Sales (PK: Transaction ID)
- Relationships:
- `Product` to `Supplier` (One-to-Many: A product may be supplied by multiple suppliers)
- `Sales` to `Product` (Many-to-One: Each sale refers to one product)
- `Sales` to `Customer` (Many-to-One: Each transaction is linked to a customer)
- `Sales` to `Store` (Many-to-One: Each sale occurs in a particular store)
Physical Design ERD
The physical design will designate data types for attributes, for instance:
- Product ID: INT
- Name: VARCHAR(100)
- Quantity on Hand: INT
- Supplier ID: INT (Foreign Key)
Conclusion: The proposed ERD is constructed to provide clarity on data relationships while ensuring that MindPlay’s database can support efficient inventory management. This will significantly enhance operational performance, provide data accuracy, and streamline accessibility to critical information (Harrington, 2016; Rob & Coronel, 2018).
