The course requires that students complete a group project. Students will go through the entire database development process from E-R model to normalization, creating tables, queries, views, forms, and reports. It is recommended that students review the hair salon database project as a template and come up with their own project ideas related to work, student groups, or social organizations. Potential project topics include scheduling applications, supply management systems, or sports statistics databases.

Students will need to develop a project proposal, design an E-R model, convert it into a relational model, normalize it to 3NF, and implement the database using SQL in Microsoft Access. They will then create queries, views, forms, and reports to demonstrate the database's functionality. Milestones include midterm and final deliverables, which consist of documentation, SQL scripts, and a short narrative on the project experience. Guidelines specify the use of UML tools for modeling, and projects should involve significant data and business logic.

Introduction

Database systems play a vital role in managing information efficiently in various organizational contexts. This paper explores the comprehensive process of developing a database system through a structured group project, aligning with course requirements. The process encompasses project proposal development, E-R modeling, relational modeling, normalization, implementation, and testing, culminating in a functional database with queries and reports. This step-by-step approach not only enhances technical skills but also fosters teamwork, problem-solving, and practical understanding of database design principles. The chosen project idea revolves around a scheduling application for resource management, which offers real-world complexity and business relevance.

Project Proposal and Domain Analysis

The initial stage involves selecting a specific and practical application domain, such as resource scheduling for a consulting firm. The problem statement emphasizes the need to effectively allocate resources like conference rooms, projectors, and portable computers to prevent conflicts while enabling utilization analysis. The primary high-level information needs include resource availability, booking schedules, utilization reports, and potential rental opportunities during low utilization periods. Understanding these requirements provides the foundation for detailed system design and ensures the database addresses real operational challenges.

E-R Modeling

Following the project proposal, an Entity-Relationship (E-R) diagram is constructed using UML notation with tools like MS Visio or LucidChart. Entities such as Resource, Reservation, and User are identified, with their respective attributes such as ResourceID, ResourceType, Date, TimeSlot, and UserID. Relationships like "books" between User and Resource, or "scheduled" between Resource and Reservation, are modeled using UML class diagrams, incorporating constraints like multiplicity (e.g., one-to-many). Enhanced features like inheritance or composition can be added, for example, differentiating between resource types.

Conversion to Relational Model

Next, the UML diagram is translated into a relational schema, where each entity becomes a table. For instance, the Resource entity converts into a Resources table with primary key ResourceID and relevant attributes. Relationships are implemented through foreign keys, such as Reservation referencing ResourceID and UserID. Proper design ensures referential integrity and enforces constraints like unique reservations per resource per time slot. Cardinality is incorporated through foreign key constraints and relational design principles, ensuring the database accurately models real-world relationships.

Normalization to 3NF

To optimize data integrity and reduce redundancy, the relational schema undergoes normalization to third normal form (3NF). This involves analyzing functional dependencies—for example, ensuring that a resource's type does not depend on its reservation details. Decomposition of relations isolates dependent attributes, promoting data consistency. For example, vendor information for equipment can be stored separately from resource details, reducing update anomalies. This process results in a normalized set of tables with clear, functional dependencies, ensuring efficient data storage and retrieval.

Implementation and Data Population

Using Microsoft Access, the normalized schema is implemented with SQL DDL statements like CREATE TABLE, incorporating primary and foreign key constraints. Data is inserted into tables covering various resource types, booking scenarios, and users to support comprehensive testing and queries. Approximately 5-8 rows per table provide realistic data and facilitate meaningful queries. The implementation phase verifies schema correctness and prepares the database for later query and report development.

Query Development and Views

SQL DML statements are crafted to answer business questions such as availability of resources, utilization rates, or scheduling conflicts. Join queries and subqueries handle complex data retrieval, illustrating database power. Views are created to provide customized perspectives for management or operational staff—such as daily resource availability or monthly utilization reports. These views support efficient decision-making and operational oversight. Additionally, forms with user-friendly interfaces are designed in Access, allowing users to make reservations, generate reports, and perform data entry seamlessly.

Final Integration and Documentation

The culmination involves integrating all components—tables, queries, views, forms—and verifying that the system functions as intended. The final deliverable includes an Access database file (.accdb), SQL scripts, and documentation summarizing the development process, challenges, and lessons learned. A brief narrative reflects on project experiences, emphasizing what was learned and potential improvements. This comprehensive process ensures students acquire practical skills in database design, normalization, implementation, and application development, preparing them for real-world data management challenges.
