Open the downloaded Access file named Exp19_Access_Ch09_CapAssessment_National_Farm_and_Agriculture_Conference.accdb. Open the Relationships window. Add the Presenters, ExhibitPresenter, Exhibits, and Locations tables to the layout. Create relationships between Exhibits and ExhibitPresenter, Exhibits and Locations, Presenters and ExhibitPresenter, ensuring you check the Enforce Referential Integrity and Cascade Update Related Fields options. Save and close the Relationships window.

Open the Performance Analyzer dialog box and select all tables. You will be given two suggestions; choose not to implement the changes and close the Performance Analyzer. Next, open the Database Documenter tool. Check the Exhibits table, set options to include Properties, Relationships, and Permissions by User and Group; include Names, Data Types, and Sizes for fields; set Indexes to Nothing. Close the Object Definition report without saving.

Create a new form based on the Presenters table with the Form tool. Save it as Add or Edit Presenters and close it. Create a navigation form using the Vertical Tabs, Left template. Add the Add or Edit Presenters form as the first item, then add the Current Presenter Schedule report, the Locations report, and the Presenters report as subsequent items. Save the navigation form as default and set it to open when the database starts. Save and close the database, then exit Access.

Paper For Above instruction

This paper outlines the comprehensive steps taken to restore and enhance the database management system for the National Farm and Agriculture Conference, ensuring data integrity, security, and user accessibility. The objective was to analyze, repair, and streamline the database that manages conference-related data, specifically addressing issues stemming from unauthorized modifications and structural inefficiencies.

Introduction

The effective management of conference data, including speaker information, exhibit details, and location logistics, is vital for the smooth execution of national events. However, in this scenario, unauthorized personnel altered critical database relationships, threatening data consistency and operational efficiency. Restoring these relationships and improving database security were necessary interventions to safeguard the system from future vulnerabilities.

Restoration of Database Relationships

A fundamental step involved examining the existing table structures and establishing appropriate relationships. The tables involved—Presenters, ExhibitPresenter, Exhibits, and Locations—are integral in managing conference data. In Microsoft Access, creating relationships with enforced referential integrity and cascade update options ensures that data remains consistent across related tables (Ralph, 2018). Specifically, relationships were created as follows:

• Between Exhibits and ExhibitPresenter, linking each Exhibit to its respective Presenter(s), with referential integrity to prevent orphan records.
• Between Exhibits and Locations, associating each exhibit with its venue, maintaining data consistency when location details are updated.
• Between Presenters and ExhibitPresenter, connecting speaker details with their presented exhibits, ensuring updates reflect uniformly across records.

These relationships adhere to normalized database principles, reducing redundancy and ensuring logical data organization (Date, 2012). By enforcing referential integrity, the database prevents deletion or modification of parent records without corresponding dependent records, thus maintaining data integrity.

Performance Analysis and Database Documentation

Using the Performance Analyzer tool allowed identification of potential performance bottlenecks, though the user chose not to implement suggested improvements, indicating confidence in the existing structure. The Database Documenter provided detailed insights into table properties, relationships, and permissions, essential for future security assessments and audits (Mannino, 2017). Including Names, Data Types, and Sizes gives a clear understanding of the table schema, facilitating maintenance and updates.

Form and Navigation Design for Data Accessibility

To enable efficient data entry and retrieval, a dedicated form was created based on the Presenters table, facilitating easier editing and addition of presenter information. Saving this as "Add or Edit Presenters" ensures clarity for users when updating data.

A navigation form with a Vertical Tabs layout was created to streamline user interaction, offering quick access to key reports and forms:

• The "Add or Edit Presenters" form allows for straightforward management of speaker data.
• The "Current Presenter Schedule" report displays upcoming presentations and schedules.
• The "Locations" report provides venue details, capacities, and features, improving logistical planning.
• The "Presenters" report offers an overview of all speakers involved in the conference.

Setting the navigation form to open automatically when the database starts enhances user workflow, reducing navigation complexity and improving overall user experience (Harrison, 2016).

Security Considerations

The initial disruption caused by unauthorized modifications underscores the importance of implementing security measures. These include setting user permissions at the table level, restricting modifications to critical relationships, and employing database passwords or user-level security features available in Access (McCarthy, 2019). Regular documentation and auditing via tools like Database Documenter can help detect unauthorized changes early.

Additionally, employing front-end/back-end database architecture separates user interfaces from data tables, reducing risks of unintentional data corruption. Using passwords and role-based security further ensures that only authorized personnel can make structural changes, safeguarding data integrity.

Conclusion

The restoration and optimization process involved meticulous re-establishment of table relationships, documentation, and interface design. These steps not only repaired the data integrity issues but also enhanced usability and security for future conference management. Incorporating security best practices is essential in preventing unauthorized access, ensuring data accuracy, and maintaining operational continuity. This structured approach underscores the importance of systematic database management in large-scale event coordination.
