IS 312 Fall 2020 Semester Database Project Specifications

IS 312: Fall 2020 Semester Database Project Specifications

1. Use data provided in the tables on pages 3-4 to draw a Data Model for this database (in a Word document).

2. Make a Data Dictionary for this database (in a Word document). Pay attention to the data types and data sizes of the keys.

3. Use MS Access to create a database with the information given in the tables. a. Create Connectivity/Relationships among tables. b. Enforce Referential Integrity. Save the database under the name “SalesAccounts” onto your local disk.

4. Create appropriate queries to answer the following questions (pay attention to the required fields and relevant tables):

  1. List all info of customers living in Utah (UT). Sort the results by City.
  2. List all info of customers living in Utah (UT) or Arizona (AZ). Sort by State.
  3. List all customers (Customer Name, City, State) who have made purchases from salesrep Mick.
  4. Show Customer Number, Customer Name, Invoice Number, Date, Item Number, Description, Unit Price, and Quantity Sold for each item on Invoice Number 103.
  5. Show Customer Number, Customer Name, Invoice Number, Date, Item Number, Description, Unit Price, and Quantity Sold for sales made in November 2014. Sort results by Customer Number.
  6. Show Item Number, Description, and Inventory Cost (UnitCost * QOH) for each item in inventory.
  7. Show the Date, Item Number, Description, Unit Price, Unit Cost, Quantity Sold, and Profit for items sold on Invoice Number 107.

Save queries under the names: “qryQuestion_1”, “qryQuestion_2”, etc.

5. Create the following Forms:

  1. Create Inventory Form for table Inventory. Create a “Textbox” to calculate Inventory Cost = [UnitCost] x [QOH] for each item.
  2. Create a Customer-Sales-Register Form in which Customer is in the Main-Form and Sales in the Sub-Form.

Save all forms; use prefix frm (frmInventory, frmCustomer-Main, frmSales-Sub).

6. Create an appropriate query to gather necessary information for the attached report sample. Save this query as qrySalesReportData. Use this query to create a Sales Report following the attached layout. The report has 2 level groupings (Salesperson and Customer). For each line item, calculate Extension = [UnitPrice] x [Quantity]. Put your name on the header of the report. Save the Report as “Sales Report”.

Paper For Above Instructions

This paper describes the process of creating a relational database as specified in the project instructions for IS 312 for the Fall 2020 semester. The project involves several key steps, including data modeling, the creation of a data dictionary, and the implementation of a database using MS Access. Additionally, the project requires the establishment of queries, forms, and a final report. Each of these elements is crucial for ensuring the relational database functions effectively and meets user requirements.

Data Modeling

To begin with, creating a data model requires a clear understanding of the data that will be included in the database. The provided tables contain significant information regarding customers, inventory, and sales invoices. By analyzing this data, a visual representation of the database's structure can be created. This includes identifying the entities (customers, inventory items, and sales) and defining the relationships between them (e.g., customers having invoices, invoices containing items).

Data Dictionary

After establishing the data model, the next step is to create a data dictionary. A data dictionary serves as a crucial reference document that outlines the data elements in the database, their data types, and the constraints applied to them. For example, for the Customer entity, fields could include CustNo (integer, primary key), Name (string, up to 100 characters), City (string, up to 50 characters), State (string, 2 characters), and CreditLimit (currency).

Database Creation in MS Access

Using the established data model and data dictionary, the next phase is to implement the database in MS Access. This involves creating tables that reflect the structure defined in the data model. Each table should enforce referential integrity to maintain data consistency. Relationships between tables can be established in Access, ensuring that the database reflects the logical relationships identified earlier.

Creating Queries

Once the database is structured, the project requires the creation of several queries. Queries are essential for retrieving specific data from the database based on various criteria. The instructions provide several specific queries to generate, for instance:

Query 1: All customers living in Utah sorted by city.

This query requires a SELECT statement that filters the Customer table for entries where the State equals 'UT' and orders the results by City.

Query 2: Customers living in Utah or Arizona, sorted by state.

Implementing this requires adjusting the WHERE clause to include both conditions and ordering by State.

Forms Creation

Creating forms in MS Access enables user-friendly data entry and viewing. The project specifies two forms:

Inventory Form: This form will facilitate the entry of inventory details. It also features a calculated textbox for displaying total inventory costs dynamically.

Customer-Sales-Register Form: This form integrates a main form for customer data and a subform for associated sales data, enhancing data entry efficiency.

Sales Report

Finally, generating a sales report involves compiling relevant sales information into a formatted document. This report should represent total sales correlating with each customer and salesperson, and include calculations for sales extensions based on unit price and quantity sold. MS Access functionalities allow grouping by Salesperson and Customer, with the results displayed in a clear layout.

Conclusion

This project exemplifies the fundamental aspects of relational database design and implementation. By utilizing MS Access, the database can be effectively structured, queried, and presented. Each deliverable—from the data model to the printed reports—serves as evidence of the project's adherence to the specifications outlined in the initial instructions.
