Open The Teachers Table And Add Three 3 More Professors Names To Th

Open the Teachers table and add three additional professors’ names to the existing list. Subsequently, access the Students_Classes table and assign at least three ClassID entries to each student, ensuring that each student is enrolled in a minimum of three classes. Next, navigate to the Course table and correct the data type of the Fee field, which is currently stored as Short Text, converting it to a numeric type with two decimal places (e.g., "400.50" should display as 400.50). After conversion, generate a report that displays the average course fee in the bottom row.

Open the Teachers_Classes table and create a lookup field for TeacherID, such that it displays the LastName of each teacher from the Teachers table corresponding to the TeacherID. To establish the referential structure, open the relationship diagram by selecting Database Tools / Relationships from the top menu. On the diagram, set up a one-to-many relationship between the Teachers table and the Teachers_Classes table via the TeacherID attribute.

Construct a query named TeachersPayByClass that shows the LastName of the teacher, ClassID, and PaymentAmount. To do this, link the relevant tables, ensuring TeacherID connects to the Teachers table to retrieve the LastName. Save the relationship diagram by pressing Control+S.

Next, create a second query called TeachersPayTotal that displays TeacherID, LastName, and TotalPay, which is the sum of the fees for all classes each teacher conducts. Format the TotalPay as currency. Use the Group By function and aggregate totals to compile the sum for each teacher.

In the Classes table, apply a validation rule to the EndingDate field, such that the class must end after May 1, 2017. Also, specify a Validation Text message to alert users if the rule is violated.

Finally, create a query named TuitionBalance that displays students’ FirstName, LastName, TotalCharge, AmountPaid, and Balance, where TotalCharge is the sum of Fees from the Course table, and Balance is calculated as TotalCharge minus AmountPaid. Format all monetary amounts as currency.

The process of managing academic data involves multiple interconnected tables and queries that streamline administrative tasks such as updating professor details, assigning students to classes, and managing financial transactions. This paper elaborates on the systematic approach to enhancing and querying an academic database based on the provided instructions, demonstrating effective data integrity practices, relationship management, and query design within a relational database environment like Microsoft Access.

First, expanding the Teachers table by adding three new professors relaxes data completeness and prepares the database for increased detail. This task involves simply inputting new records with relevant professor information into the Teachers table, ensuring that data entries are accurate and consistent. Such an update not only helps in maintaining an up-to-date faculty list but also facilitates accurate reporting and relationships in subsequent tables.

Next, assigning students to multiple classes in the Students_Classes table is crucial to accurately reflect course enrollments. By ensuring each student is linked to at least three ClassID entries, the database captures the complexity of student schedules and promotes a comprehensive overview of academic offerings. This step involves updating the Student-Classes junction table with additional ClassID records, which enhances the robustness of enrollment tracking.

Converting the Fee field in the Course table from Short Text to a numeric data type with two decimal places addresses data consistency and facilitates numerical calculations. After changing the data type, it's necessary to update the existing records to match the new format, ensuring that all fee entries are correctly interpreted as real numbers. Once converted, calculating the average course fee provides useful insights into the fee structure, aiding administrative and financial decisions.

Establishing a lookup field in the Teachers_Classes table for TeacherID that displays the teacher’s last name improves data readability and user interaction. This involves creating a lookup set that references the LastName field in the Teachers table, making it easier for users to identify teachers without memorizing IDs. Following this, the relationships diagram must be modified to set a one-to-many relationship between the Teachers table and Teachers_Classes table through the TeacherID key, ensuring referential integrity in the database.

Creating the TeachersPayByClass query enables administrators to view payment details per class, associating teacher names with class IDs and payments received. This is achieved by linking the Teachers, Teachers_Classes, and Payment tables, selecting relevant fields, and executing a join query. Saving the relationship diagram with proper links ensures data consistency for future queries and updates.

The TeachersPayTotal query aggregates total payments received by each teacher across all classes, utilizing the Group By function and summing the PaymentAmount field. Formatting the resulting TotalPay as currency provides a clear financial overview by teacher, which can be useful for payroll, budgeting, and financial analysis.

Applying a validation rule to the EndingDate field within the Classes table ensures data accuracy by enforcing that classes end after May 1, 2017. The Validation Text acts as an alert message, guiding data entry and preventing logical errors in scheduling.

Finally, the TuitionBalance query calculates each student’s financial standing by summing the Fee in the Course table for all enrolled classes, deducting the AmountPaid, and presenting the resulting Balance. Formatting all monetary figures as currency enhances clarity. This report provides stakeholders with a comprehensive view of tuition receivables and outstanding balances, efficiently supporting financial management.
