Writea Response Of No More Than 1050 Words To Problem 1 From Ch 6

Write a response of no more than 1,050 words to Problem 1 from Chapter 6, "Purchases and Payments Business Process" on page 146 of Accounting Information Systems. The scenario involves the Tablet Store, which recently opened to sell tablets, purchasing directly from manufacturers such as Apple, Samsung, and Dell. The process for purchasing tablets begins with an employee submitting an electronic purchase order to the manufacturer, including multiple models from a single manufacturer. The manufacturers typically deliver the tablets within two weeks, and the store pays within 30 days after receipt. Payments may be combined for multiple receipts from the same manufacturer and are drawn from a single bank account.

The assignment includes three tasks:

  1. Draw a UML class diagram that describes the Tablet Store’s purchases and payments process.
  2. Using Microsoft Access, implement a relational database based on the UML class diagram, including at least three fields per table.
  3. Describe how to use this relational database to determine the Tablet Store’s accounts payable.

Sample Paper For Above instruction

Introduction

The Tablet Store’s purchasing and payments process exemplifies a typical supply chain and financial transaction management system within a retail environment. Efficient management of purchase orders, inventory, and accounts payable is critical for maintaining profitability and ensuring timely procurement of inventory. This paper provides a comprehensive overview of this process through a UML class diagram, a demonstration of the relational database implementation in Microsoft Access, and an explanation of how the database supports accounts payable management.

UML Class Diagram for the Purchases and Payments Process

The UML class diagram represents the core entities involved in the Tablet Store’s purchasing system: PurchaseOrder, Manufacturer, Shipment, Payment, Invoice, and TabletModel. The relationships among these entities depict the flow from order placement to payment processing.

Entities and Attributes:

  • Manufacturer: manufacturer_id (PK), name, contact_info
  • TabletModel: model_id (PK), name, manufacturer_id (FK), price
  • PurchaseOrder: order_id (PK), order_date, manufacturer_id (FK), total_amount
  • PurchaseOrderLine: order_line_id (PK), order_id (FK), model_id (FK), quantity, line_total
  • Shipment: shipment_id (PK), order_id (FK), shipment_date, arrival_date, total_shipment_cost
  • Invoice: invoice_id (PK), shipment_id (FK), invoice_date, amount_due, due_date
  • Payment: payment_id (PK), invoice_id (FK), payment_date, amount_paid, payment_method

Relationships:

  • Manufacturer supplies multiple TabletModels, linked via manufacturer_id.
  • PurchaseOrder is placed to a specific Manufacturer, with multiple PurchaseOrderLines detailing different tablet models and quantities.
  • Shipment corresponds to a PurchaseOrder, indicating when and how tablets are delivered.
  • Invoice is generated from a Shipment, reflecting the amount payable.
  • Payment relates to an Invoice, capturing the actual payment activity.

Implementing the Database in Microsoft Access

The UML diagram is translated into a relational database with tables corresponding to each entity. Fields are carefully chosen with primary keys (PK) and foreign keys (FK) to enforce referential integrity.

  • Manufacturer Table: manufacturer_id, name, contact_info
  • TabletModel Table: model_id, name, manufacturer_id (FK), price
  • PurchaseOrder Table: order_id, order_date, manufacturer_id (FK), total_amount
  • PurchaseOrderLine Table: order_line_id, order_id (FK), model_id (FK), quantity, line_total
  • Shipment Table: shipment_id, order_id (FK), shipment_date, arrival_date, total_shipment_cost
  • Invoice Table: invoice_id, shipment_id (FK), invoice_date, amount_due, due_date
  • Payment Table: payment_id, invoice_id (FK), payment_date, amount_paid, payment_method

This structure facilitates detailed tracking of purchase orders, shipments, invoices, and payments, enabling accurate record-keeping and analysis.

Utilizing the Database to Determine Accounts Payable

The accounts payable (AP) represents the amount owed by the Tablet Store to its suppliers. Using the relational database described above, AP can be determined by aggregating the outstanding amounts on invoices that have not yet been paid.

  1. Identify unpaid invoices: Query the Invoice table for records where there is no corresponding record in Payment with a payment_date earlier than the invoice's due_date.
  2. Calculate total outstanding amount: Sum the amount_due for these unpaid invoices.
  3. Linkages: By joining the Invoice table with Shipment, PurchaseOrder, and Manufacturer, the store can analyze which suppliers or orders contribute most to current liabilities.

This method ensures accurate and timely determination of the store’s current accounts payable, aiding in cash flow management and vendor relations. Regularly updating this query allows the store to maintain a real-time picture of its liabilities.

Conclusion

The integration of UML diagrams, relational database implementation, and strategic querying forms a robust framework for managing the Tablet Store’s purchasing and payments process. Automating these activities enhances operational efficiency, reduces errors, and provides better insights into liabilities such as accounts payable. The described system models real-world transaction flows, ensuring compliance with accounting principles and supporting effective financial management.
