EX19_AC_CH06_GRADER_CAP_AS_Instructions.docx Grader - Instructions Access 2019 Project Exp19_Access_Ch06_Cap - Insurance 1.0 Project Description: You have been asked to modify a database that tracks driver data and insurance details. You will update, add to, and delete records from tables. You will also create queries that aggregate data, find unmatched, and find duplicate values. Steps to Perform: Step Instructions Points Possible 1 Start Access. Open the downloaded Access file named Exp19_Access_Ch6_Cap_Insurance. Grader has automatically added your last name to the beginning of the filename. Save the file to the location where you are storing your files. Open the Drivers table, observe the data, and then close the table. Create an update query based on the Drivers table. Include all of the fields from the table. Set the criteria to update Special drivers to Senior. Run the query, save it as Update Class, and then close the query. Create a make table query based on the Drivers table. Include all of the fields from the table. Set the criteria to select Senior drivers. The query should make a new table named Non-Standard Drivers in the current database. Run the query, save it as Make Non-Standard Drivers and then close the query. Make a copy of the Make Non-Standard Drivers query and save it as Append Non-Standard Drivers. Change the query type to Append and append records to Non-Standard Drivers. Set the criteria to select Minor drivers. Run, save, and then close the query. Set DriverID as the primary key field of the Non-Standard Drivers table. Save and close the table. Make a copy of the Append Non-Standard Drivers query and save it as Delete Non-Standard Drivers. Change the query type to Delete. Set the criteria to select Minor or Senior drivers. Run, save, and then close the query. Create a crosstab query based on the Non-Standard Drivers table. Set Class as the row heading field and Gender as the column heading field. Summarize the data by counting the DriverIDs. Save the query using the default name, and view the query results. Modify the query so that Class displays as the column heading and Gender displays as the row heading. Save the query as Non-Standard Drivers_Crosstab and run the query. Modify the database (Non-Standard Drivers table) so that the gender M displays as Male and F displays as Female. Run the crosstab query again to display the changes. Close the query. Create a find duplicates query based on the Drivers table where there is a repeated LastName and Street value. Add the DriverID and FirstName fields to the query results. Save the query using the default name, and view the query results. Note that Eric and Kirk Abelson live at the same address, but have two different DriverIDs. In the Drivers table, expand the Subdatasheet for Eric and notice that he carries insurance for both household vehicles. Close the table and the query. Create an unmatched query to find drivers in the Drivers table who have no insurance listed in the Insurance table. Include all fields from the Drivers table. Save the query using the default name, and view the query results. For the driver named Lawrence Alexander, add a record to the Insurance table. Enter the InsuranceID number as 10010, the DriverID as, and the Agent as AS8842. Populate the remaining fields (AutoType, AutoYear, TagID, and TagExpiration) with data of your choice. Close the table. Run the Drivers Without Matching Insurance query again. Note that Lawrence Alexander no longer appears in the results, as you have used the query to identify missing data and corrected the error. Kirk Abelson is covered under the same policy as Eric, his father. Close the query. Close all database objects. Close the database and then exit Access. Submit the database as directed.

Sample Paper For Above instruction

In this paper, I will demonstrate a comprehensive understanding and practical application of database management principles using Microsoft Access 2019, specifically focusing on modifying and querying a database that tracks driver and insurance information. The project aims to enhance data accuracy, improve reporting capabilities, and ensure data integrity within the existing database structure. This process involves performing various operations such as updating records, creating different types of queries, and managing tables to support effective data analysis and reporting.

Introduction

The importance of efficient database management in the transportation and insurance sectors cannot be overstated. Accurate and consistent data ensures proper risk assessment, claims processing, and policy management. Microsoft Access serves as a suitable tool for implementing these tasks due to its user-friendly interface and robust query capabilities. The specific project instructions involve multiple steps, beginning with querying and updating driver data, creating aggregated data reports, and managing duplicate records, all of which contribute to maintaining a high-quality database system.

Updating Records

The initial step involves opening the Drivers table and reviewing the existing driver data for accuracy. A key operation is creating an update query that changes any driver classified as a ‘Special driver’ to ‘Senior’. This update ensures that driver classifications are current and reflect their actual status. Executing this query and subsequently saving it as ‘Update Class’ allows for straightforward future modifications, ensuring consistent data management.

Similarly, making a make-table query that duplicates the Drivers table data but filters only senior drivers provides a snapshot of the senior driver population. This filtered table, named ‘Non-Standard Drivers,’ is useful for targeted outreach or policy adjustments. The process of saving queries and tables facilitates efficient data handling and minimizes manual errors.

Data Management and Integrity

The project emphasizes managing duplicate data, such as identifying duplicate last names and addresses, to prevent redundancy. Creating find duplicates queries helps streamline data and detect anomalies, which is vital for maintaining the integrity of the database. Additionally, an unmatched query identifies drivers without insurance, highlighting gaps in data coverage and enabling corrective actions.

Adding new records, as exemplified by entering insurance details for Lawrence Alexander, demonstrates the dynamic nature of the database. It also highlights the importance of ensuring that all related data tables—drivers and insurance—are synchronized to provide accurate and comprehensive information.

Data Analysis and Reporting

The creation of crosstab queries allows for insightful data summaries, such as analyzing the distribution of driver classes by gender. Modifying these queries to display data in different formats enhances interpretability. For example, changing class to column headings and gender to row headings offers an alternative view, aiding in understanding demographic compositions within the driver population.

Standardizing data formats, such as displaying gender abbreviations as full words (‘Male’ and ‘Female’), improves report clarity. Running these queries after data modifications confirms that the database displays consistent and accurate information, supporting effective decision-making.

Conclusion

Overall, this project demonstrates the critical functions of database management using Microsoft Access, including data updating, query creation, duplicate detection, and data correction. By following best practices such as saving queries, managing primary keys, and ensuring data consistency across related tables, users can maintain a reliable, efficient, and insightful database system that supports ongoing operational needs and strategic decisions.
