Access 2013 Chapter 3 Creating and Using Queries Last Updated: 2/27/15

The assignment involves using Microsoft Access 2013 to create and modify summary queries based on a provided start database file. You will create three queries: one summarizing the number of tickets issued by city and violation, another summarizing total tickets by violation, and a third providing total fines assessed against individual drivers. The tasks include designing queries in Design view, adding fields, applying aggregate functions, sorting results, editing queries, and saving your work. You will then run the queries to verify their accuracy, adjust field widths for readability, and save copies with appropriate names. The project demonstrates skills such as creating summary queries, editing queries, applying sorting and aggregate functions, and executing and saving queries within Access 2013.

Sample Paper For Above instruction

In this paper, I will detail the process of creating and using queries in Microsoft Access 2013 to meet the needs of the New York State Department of Motor Vehicles (DMV). The project entails generating three specific queries that provide summarized data on tickets issued, violations, and fines. These queries facilitate efficient data analysis and reporting, consolidating vast amounts of records into meaningful summaries that support decision-making and policy evaluation.

Introduction

Database querying plays a crucial role in managing large datasets efficiently. The ability to create, modify, and execute queries allows users to extract relevant information, generate reports, and support operational needs. Microsoft Access 2013 offers a user-friendly environment for designing queries, particularly summary or aggregate queries, which are essential for compiling data summaries. This project involves setting up three such queries based on a provided database, emphasizing skills in design view, field selection, sorting, grouping, and aggregate functions.

Creating the First Query: Tickets Count by City and Violation

The first step involved opening the given database file, ensuring content activation if security warnings appeared. Using Design view, I added the Ticket table to the query. To capture the required data, I included the fields: City, PrimaryFactor, and TicketNumber, enlarging the table display for ease of field selection. I then added the Total row, setting City and PrimaryFactor to 'Group By' and TicketNumber to 'Count.' This configuration produces a summary showing the number of tickets issued per city and violation factor. I saved this query as 'TicketCountByCityAndFactor.'

Executing the query displayed 20 records, which I then formatted by resizing columns to fit content. I saved this layout for readability. To facilitate further analysis, I saved a copy under a new name, 'TicketCountByFactor.' I then edited this second version, removing the City field and sorting the TicketNumber counts in descending order, highlighting the most frequent violations. After running and confirming the correctness, I closed the query.

Creating the Second Query: Total Fines per Driver

The second query aimed to aggregate total fines assessed to each driver. I added both relevant tables—drivers and tickets—to the query design window, enlarging their display for clarity. I included fields: LicenseNumber, FirstName, LastName, Fine, and TicketNumber. I applied the Total row, grouping by LicenseNumber, FirstName, and LastName, while summing the Fine field and counting TicketNumber. Sorting was set to descending on the total Fine amount to see the highest fines first. I saved the query as 'TicketsByDriver.'

Running the query yielded data for 21 drivers, sorted from highest to lowest total fines, confirming it met the project requirements. These steps demonstrated the ability to perform aggregations and sorting to summarize financial data related to tickets.

Analysis and Reflection

The process of creating these queries underscored the utility of Microsoft Access's design features for data summarization. By efficiently using groupings, aggregate functions, and sorting, I was able to quickly generate summaries that support operational oversight and reporting. These skills are vital in managing large datasets, as they allow for quick insights into ticket distributions and financial liabilities.

Conclusion

This project exemplifies essential database skills such as designing summary queries, editing query parameters, applying aggregate functions, and formatting query outputs for clarity. The ability to generate quick summaries helps organizations like the DMV in tracking data trends, preventing misconduct, and allocating resources effectively. Mastery of query design in Access is thus crucial for data-driven decision making in various fields.
