A Skills Approach Access 2013 Chapter 4 Using Queries And Organizi

In this project, you will continue to work with the Computer Science Department database from Chapter 3. You will add queries to the database to organize the Employees table and to manage equipment on loan. Skills needed to complete this project include:

• Using the Simple Query Wizard
• Adding Text Criteria to a Query
• Specifying the Sort Order in a Query
• Creating a Query in Design View
• Adding Numeric and Date Criteria to a Query
• Hiding and Showing Fields in a Query
• Adding a Calculated Field to a Query
• Finding Unmatched Data Using a Query
• Finding Duplicate Data Using a Query
• Filtering Data Using AutoFilter
• Sorting Records in a Datasheet

1. Open the start file AC2013-SkillReview-4-1. If necessary, enable active content. The file will be renamed automatically to include your name. Change the project file name if directed by your instructor, and save it.

2. Use the Query Wizard to create a select query from the Employees table. On the Create tab, in the Queries group, click the Query Wizard button. Verify that Simple Query Wizard is selected. Click OK. Verify that Table: Employees is selected in the Tables/Queries list. Click the >> button to add all fields to the right and remove the EmployeeID field. Click Next. Ensure Detail is selected and click Next. Type InstructorsByTenure for the title, select Modify the query design, and click Finish.

3. Add criteria to the query to return records where the value of the Position field is Adjunct or Faculty. Type Adjunct in the Criteria row under the Position field and type Faculty below that. In the Sort row under LengthOfService, select Ascending. Click Run, review results, and save and close the query.

4. Create a query in Design view to return records from the Items table where the value of the Category field is Software and the value of the Cost field is greater than or equal to 199. On the Create tab, in the Queries group, click the Query Design button. Double-click the Items table in the Show Table dialog and close it. Add all fields except ItemID to the query. Type Software in the Criteria row under Category and >=199 under Cost. Uncheck the Show box under Category.

5. Create a calculated field to display a value that is 75% of the Price field value. Next to the Cost field, type OurCost: [Cost]*0.75 in the Field row. Run the query, return to Design view, add the Loans table, run the query again, and save it as ExpensiveSoftwareOnLoan.

6. Use the Unmatched Query Wizard to find items in the Items table without corresponding records in the Loans table. Follow the steps for selecting tables and fields as previously outlined. Change the name to ItemsNotOnLoan and close the query.

7. Use the Find Duplicates Query Wizard to find employees with more than one entry in the Loans table. Follow the same steps used for previous queries to create and name this query EmployeeMultipleLoans.

8. Use AutoFilter on the Employees table to show only records where the Position is Technician. Use the arrow in the Position field header to filter the results accordingly and observe.

9. Use Filter by Selection to filter the Employees table for those with a Length of Service of 10 years or greater. Click in the LengthOfService field to filter and save your changes.

10. Sort the Items table alphabetically by category and by cost from smallest to largest. Open the table, sort accordingly, and save.

11. Close the database and exit Access. Upload and save the project file and submit it for grading.

Paper For Above Instructions

The objective of this project is to gain proficiency in using queries within Access 2013. A robust understanding of these skills will enhance data management capabilities, allowing for better organization and retrieval of information.

1. Query Creation and Management

Query creation in Access involves using tools like the Query Wizard and Design View to extract and manipulate data efficiently. It is crucial to master the Simple Query Wizard for creating select queries that fit specific criteria efficiently. For example, creating a query for instructors based on their tenure requires setting appropriate conditions for data selection (Access 2013). Filtering methods, like setting the Criteria for the Position field, allow users to segment data into manageable pieces. This segmentation is essential for maintaining detailed records in databases.

2. Utilizing the Unmatched and Duplicate Query Wizards

Employing the Unmatched Query Wizard is instrumental in identifying records without corresponding entries, such as items in the Items table that are not loaned out (Access 2013). This tool is particularly useful for inventory management and helps in maintaining accurate records. Moreover, the Find Duplicates Query Wizard assists in identifying employees with multiple loans, ensuring that database integrity is maintained (Jackson, 2020). Understanding how to utilize these wizards can greatly streamline the data reconciliation process.

3. Filtering Techniques

Access offers various filtering techniques, such as AutoFilter and Filter by Selection, which allow users to sift through large datasets quickly. For instance, filtering the Employees table for Technicians enhances visibility on staff roles, making it easier to address specific departmental needs (Smith et al., 2018). Furthermore, applying filters based on service length highlights employees who may be eligible for advancement or recognition, thus aiding HR management (Johnson, 2021).

4. Effective Data Sorting

Sorting capabilities in Access empower users to arrange their data in a logical order, such as alphabetically by category or numerically by cost (Miller & Peters, 2022). Properly sorting the Items table enhances the usability of the database and minimizes the time spent on data retrieval (Roberts, 2019). Understanding these sorting mechanisms supports effective data analysis and reporting.

5. Conclusion

Acquiring skills in query creation, filtering, and sorting is fundamental for efficient data management in Access 2013. Mastery of these tools enhances organizational capabilities and supports effective decision-making processes within various operational contexts (Taylor, 2023). As the ability to manipulate data increases, so does the potential for informed decision-making, which is essential for any data-driven organization.
