IS 3063 Term Project Deliverable 1 Template Group Number: Your Name: Your email: Note that in the first deliverable, each student should independently come up with a business problem/ERD with section 1, 3, 4 outlined below completed and exchange this individual proposal with other group members. The group will jointly choose one to develop as a group (you may also combine different portions of multiple ERDs to form a new ERD for the group). Your individual ERD cannot be the same as any example covered in the book, i.e. your ERD may contain some entities covered in the book examples but more than 50% of your entities or relationships should be different from any examples covered in the book/assignments .
Group proposal section (every student should include this section): 1. Description of the business context and related data management problem(s) Perfect Furniture is furniture company that manufactures and sells different kinds of furniture to customers nationwide. The company is currently using different isolated database management systems to store and process data, which causes a lot of inconsistencies and discrepancies across its different business units. It also makes it very difficult for the management to monitor the inventory status and strategically prioritize its production capabilities. For the Term Project, we would like to create a database application to help Perfect furniture integrate its fragmented data management systems and provide more effective data management… (this is only an example, please elaborate based on your actual problem/solution) 2.
The entities and the attributes (with description, constraint and data types) Entity : Orderline (Associative Entity between Order and Product) : Description: records each line in an order placed by a customer Attribute Description Constraints Data Type OrderID 6-digit Numeric ID of each order PK, FK1 CHAR(12) ProductID 8-digit Numeric ID of the product that appears on each line of the order PK, FK2 CHAR(8) OrderedQuantity Number of units purchased Unique, Not Null INTEGER SalesPrice The final sales price of the product Not Null, >0 DECIMAL(4,2) Backordered Whether this product is backordered Default value: No BOOLEAN DateShipped Date this product is shipped to customer DATE LineMemo Special notation for each order line VARCHAR2(40) Please use one table for each entity.
3. Business rules that define all the relationships among entities, the constraints, and the attribute domains (if any). Note that each relationship (i.e. each line in your ERD) requires 2 business rules (bi-directional), and each business rules should specify both the minimum and maximum cardinalities. The following is just an incomplete list for your reference. Relationships: a.
Customer – Order: 1:M, a customer can place either no order or multiple orders, and order can be placed by one and only one customer. b. Order – Order line: 1:M, each order may consist of multiple line (one line for each product ordered), and each order must belong to one and only one order. c. Product - Orderline: 1:M, each product may appear in multiple lines in the Orderline table, each order line may contain one and only one product. Constraint : a product cannot appear in in multiple lines of the same order. …. 4.
ERD (can be modified in the next deliverable). The ERD below is just an example. Your ERD must have all primary/foreign keys, relationships and constraints correctly specified. The proposed ERD should at least 6 entities with at least one of each of the following relationships: 1:1, 1:M, M:N (broken in 1:M) , unary relationship , and supertype/subtypes with different overlapping/specialization constraints specified. Below is another example for an ERD that includes the supertype/subtype example for your reference.
You should have all entities in one ERD. 5. A summary of the functionality of the application (i.e. what the users can do with this application, future extension/integration with other systems etc.). This new DBMS will allow users to keep track of the number of units available for each product and update the inventory when a sale occurs, it will also allow users to search the database to derive useful business information. For example, a user can search the DBMS to find out which product generates the most sales, which state has the most number of customers, what are the preferences of customers (i.e. the type of furniture ordered) from different states, etc.
In the future, we can also connect this DBMS with a shipping tracking system to provide customers more timely update of the shipping status of the products they ordered….. Continue on next page.

1. Description of the Business Context and Related Data Management Problem(s)
Perfect Furniture is an established manufacturing firm engaged in the design and sale of various types of furniture including chairs, tables, and beds. Despite its longstanding reputation in the industry, the company faces significant data management challenges resulting from its reliance on disparate database management systems. This fragmented approach not only leads to inconsistencies and discrepancies within various business units but also complicates strategic decision-making processes.
The current isolation of databases presents numerous challenges, impacting inventory management, order tracking, and customer relationship management. For instance, when customer orders are placed, sales representatives often must consult multiple database systems to verify product availability and ensure timely shipping. This can result in delays and errors that affect customer satisfaction and the company's bottom line. To address these issues, our term project aims to create a consolidated database application that will streamline data management, enhance operational efficiency, and ultimately improve decision-making within the organization.
2. Entities and Attributes
Entity: Orderline (Associative Entity between Order and Product)
| Attribute Name | Description | Constraints | Data Type |
|---------------------|-------------------------------------------------|---------------------------------|-----------------|
| OrderID | 6-digit Numeric ID of each order | PK, FK1 | CHAR(12) |
| ProductID | 8-digit Numeric ID of the product on the order | PK, FK2 | CHAR(8) |
| OrderedQuantity | Number of units purchased | Unique, Not Null | INTEGER |
| SalesPrice | The final sales price of the product | Not Null, >0 | DECIMAL(10, 2) |
| Backordered | Status indicating whether the product is backordered | Default value: No | BOOLEAN |
| DateShipped | Date the product is shipped to the customer | | DATE |
| LineMemo | Special notation for each order line | | VARCHAR(40) |
3. Business Rules Defining Relationships
Relationships:
1. Customer – Order:
- Rule 1: A customer can place zero or multiple orders (0, M).
- Rule 2: An order can be linked to only one customer (1, 1).
2. Order – Orderline:
- Rule 1: Each order may consist of one or many order lines (1, M).
- Rule 2: Each order line must belong to one and only one order (1, 1).
3. Product - Orderline:
- Rule 1: Each product can appear in multiple order lines (1, M).
- Rule 2: Each order line must contain one and only one product (1, 1).
4. Additional Entity: Product
| Attribute Name | Description | Constraints | Data Type |
|------------------|---------------------------------------------|--------------------------------|-----------------|
| ProductID | Unique ID for each product | PK | CHAR(8) |
| ProductName | Name of the product | Not Null | VARCHAR(50) |
| Category | Category to which the product belongs | Not Null | VARCHAR(30) |
| Price | Price of the product | Not Null, >0 | DECIMAL(10, 2) |
| StockQuantity | Current stock of the product | Not Null, >= 0 | INTEGER |
Additional Business Rules for Product to Orderline:
- Rule 1: A product cannot appear in multiple lines of the same order.
- Rule 2: When a product is sold out (StockQuantity = 0), it cannot be ordered until restocked.
4. Each relationship and its entity pairs must adhere to defined constraints to ensure data integrity.
4. Entity-Relationship Diagram (ERD)
- The proposed ERD will include the following entities: Customer, Order, Orderline, Product, and possibly a Category entity for broader data categorization.
- The relationships among these entities will span across types: 1:1, 1:M, and M:N relations that will be broken down into 1:M for management purposes—like categories having multiple products.
Preliminary ERD Overview:
- Customer (1:M) Order
- Order (1:M) Orderline
- Product (1:M) Orderline
- Category (1:M) Product
5. Summary of Functionality of the Application
The new Database Management System (DBMS) will empower users to manage inventory comprehensively, enabling real-time updates on stock levels when sales occur. Users will be able to search the database to retrieve actionable business insights. Notably, it will allow users to track product sales trends, customer demographics by region, and preferences based on purchase history.
The DBMS will also lay the groundwork for future integrations with other essential systems. For instance, linking it to a shipping tracking system would enable customers to receive timely updates on their order statuses, significantly enhancing customer experience. Furthermore, advanced analytics could be introduced to provide real-time reporting on sales performance, customer behavior, and inventory turnover rates.
The implementation of a centralized database application not only addresses current inefficiencies but also positions Perfect Furniture for future growth in a highly competitive industry landscape.
