A Ch02 Gov1 H3 Instructions

In this project, you will use a database to answer questions about scholarships awarded to students at a college. You will create a relationship between two tables, create a query from an existing query, and create queries using text, numeric, compound, and wildcard criteria based on the fields in one or both tables. You will create calculated fields, group data when calculating statistics, create a crosstab query, and create a parameter query.

Instructions:

For grading purposes, perform the following tasks:

  1. Start Access, open the file named go_a02_grader_h3_Student_Scholarships.accdb, and enable content.
  2. Using Student ID as the common field, create a one-to-many relationship between the Students table and the Scholarships Awarded table, enforce referential integrity, and enable cascade options.
  3. Create a relationship report with default name and save it; then close all objects.
  4. In the Students table, change the Student ID in the last record, then close the table.
  5. Copy the query named "Amount $500 or More" and rename the new query "Awards 4th Qtr Query". Redesign the query to display Scholarship Name, Award Date, Amount, and Student ID in that order. Sort records ascending by Award Date, filter to show only awards between 10/1/18 and 12/31/18. Run, save, and close the query.
  6. Create a query based on Scholarships Awarded table to display Scholarship Name, Major, and Amount, sorted descending by Amount, with criteria for Major being Math or Business, and Amount greater than 200. Save as "Math OR Business Over $200 Query".
  7. Create a query based on Students table to display City, Student ID, Last Name, First Name, sorted ascending by City, Last Name, First Name. Criteria: City starting with "L". Save as "L Cities Query".
  8. Create a query based on Students table to display Student ID, First Name, Last Name, Address, City, State, Postal Code. Criteria: missing Postal Code. Save as "Missing Postal Code Query".
  9. Create a query joining both tables to display Scholarship Name, First Name, Last Name, and Amount, sorted by Scholarship Name. Add calculated fields "Board Donation" (50% of each scholarship) and "Total Donation" (Amount + Board Donation). Run, format as currency with 0 decimal places, save as "Board Donation Query".
  10. Create a query on Scholarships Awarded table displaying Major and Amount, sorted descending by Amount, with sum total of Amount, formatted with 0 decimal places, saved as "Amount by Major Query".
  11. Use Query Wizard to create a crosstab query with Student ID as row headings, Major as column headings, summing Amount, formatted with 0 decimal places, saved as "Student ID and Major Crosstab Query".
  12. Create a parameter query prompting for Major, displaying Scholarship Name and Amount, filtering for entered Major, hiding the Major field, saving as "Major Parameter Query".
  13. Close all objects, exit Access, and submit the database as directed.

Sample Paper For Above instruction

The following paper provides a comprehensive walkthrough of the specified tasks for managing and querying a scholarship database in Microsoft Access. Each step aligns with the instructions to demonstrate expertise in relational database management, query creation, data analysis, and report generation.

Introduction

Managing student scholarship data efficiently requires a well-structured relational database and skillful use of queries. This project simulates real-world database tasks including establishing relationships, creating various types of queries, and generating reports that facilitate insightful analysis of scholarship awards. By mastering these techniques within Microsoft Access, users can enhance data integrity, generate meaningful reports, and support decision-making processes at educational institutions.

Establishing Database Relationships

The initial step involves opening the provided database file, “go_a02_grader_h3_Student_Scholarships.accdb,” and enabling content. A fundamental relational database principle is establishing links between related tables; here, the relationship between Students and Scholarships Awarded tables is based on the Student ID field. Creating a one-to-many relationship with referential integrity ensures each student can have multiple scholarship awards, and enforcing cascade updates guarantees consistency if a Student ID changes. This relationship setup supports accurate data retrieval and update operations across tables.

Creating Relationship Report

A relationship report visually documents the connections between tables, aiding understanding and troubleshooting. Generating this report with default settings provides a clear illustration of the database's relational structure. Saving and closing the report ensures the database is organized and ready for further query development.

Data Modification and Propagation

Changing the Student ID in the last record of the Students table exemplifies data maintenance. Because referential integrity with cascade updates is established, this action automatically updates related records in the Scholarships Awarded table, preserving consistency across the database.

Query Design and Customization

The project then involves creating multiple queries, each designed to extract specific data patterns:

  • The “Awards 4th Qtr Query” filters scholarships awarded between October 1, 2018, and December 31, 2018, displaying the Scholarship Name, Award Date, Amount, and Student ID. Sorting is set to ascending by Award Date for chronological analysis.
  • The “Math OR Business Over $200 Query” retrieves scholarship awards for Math or Business majors with amounts exceeding 200, sorted descending by amount, highlighting significant awards in these fields.
  • The “L Cities Query” lists students residing in cities starting with “L,” sorted alphabetically, aiding geographic analysis.
  • The “Missing Postal Code Query” identifies students with missing postal codes, facilitating data cleanup and completeness checks.

Joining Tables and Calculated Fields

A critical aspect involves creating a joined query to combine student and scholarship data. Adding fields such as Scholarship Name, First and Last Names, and Amount lays the foundation. Then, calculated fields “Board Donation” (50% of each scholarship amount) and “Total Donation” (sum of scholarship and donation) provide insight into fundraising contributions. Formatting these currency fields ensures clarity in financial reports.

Data Aggregation and Crosstab Queries

To analyze aggregate scholarship data, queries compute total amounts per Major, sorted descending, with formatting for presentation. A crosstab query visualizes scholarship distribution across students and majors, with row and column labels, and summed amounts, streamlining multidimensional analysis.

Parameter Queries for User Input

Finally, parameter queries prompt users to specify criteria at runtime, such as entering a Major. This flexibility allows tailored reports without creating multiple static queries. By hiding the Major field from results, the query maintains focus on relevant data, enhancing user experience.

Conclusion

This comprehensive set of tasks demonstrates proficiency in database management, query design, and reporting within Microsoft Access. Establishing relationships ensures data integrity. Customized queries facilitate nuanced data analysis, and calculated fields enable financial insights. By adhering to best practices, users can transform raw data into actionable intelligence and support institutional decision-making effectively.
