Access Capstone/Access Capstone/Access 2013 Part 2 - Lab Test A

Create a fresh GetItNow Electronics database. Execute queries to retrieve and manipulate data from the Sales Rep and Outlet tables based on specified criteria, including displaying all records, selecting specific fields with filters, sorting, calculating averages, and joining tables. Save each query with a designated name. Close the database after completing all tasks.

Access Capstone/Access Capstone/Access 2013 Part 2 - Lab Test A

The primary goal of this assignment was to demonstrate proficiency in creating and executing various queries within a Microsoft Access database specifically tailored for an electronics shop’s operations. The tasks involved designing queries that extract, filter, sort, and join data from two core tables — the Sales Reps and Outlets tables — emphasizing the importance of accurate data retrieval for effective business decision-making.

To begin, I created a new database titled "GetItNow Electronics," following the prescribed structure for both the Sales Reps and Outlets tables. Care was taken to define the appropriate data types, set primary keys correctly, and input the provided sample data to ensure a realistic and functional database. The primary key assignments for Sales Rep ID and Outlet ID ensured proper relational integrity, facilitating effective joins later.

Basic Data Retrieval and Filtering

The first queries focused on simple retrievals, such as displaying all records from the Sales Reps table (Lab Test Step 2) and selecting specific fields like Sales Rep ID, Outlet ID, and Quota (Lab Test Step 3). These foundational queries established fluency in creating basic select queries. Subsequent filters refined data further: filtering by gender (Lab Test Step 4), hire date conditions (Lab Test Step 5), and specific Outlet IDs coupled with quotas (Lab Test Step 6). These queries helped in understanding how criteria work and how to use criteria expressions effectively.

Advanced Filtering and Sorting

More complex queries incorporated pattern matching, such as selecting Sales Reps with IDs beginning with a certain digit (Lab Test Step 7), or using logical OR conditions to filter by hire date or quota (Lab Test Step 8). Sorting data in ascending and descending orders was demonstrated in Lab Test Steps 10 and 11, emphasizing the importance of ordered data for analysis and reporting purposes. Using parameters (Lab Test Step 10) illustrated interactive query design, enabling dynamic filtering based on user input, which is essential for flexible database reports.

Aggregate Functions and Join Operations

The assignment also involved employing aggregate functions such as AVG to calculate mean values (Lab Test Step 15), and identifying maximum values for specific criteria (Lab Test Step 14). These are vital tools for summarizing data across groups. The join operation in Lab Test Step 12, connecting the Sales Reps and Outlets tables using common fields, demonstrated how relational databases combine data from multiple sources, providing comprehensive insights. Restricting joined data with specific criteria in Lab Test Step 13 further exemplified multifaceted data querying capabilities.

Concluding Remarks

Completing these queries reinforced essential skills in database management: designing appropriate queries, using criteria for filtering, sorting effectively, performing calculations, and establishing table relationships. The practice reflected real-world scenarios in retail and sales contexts, where managers rely on accurate, filtered data to make strategic decisions. This comprehensive exercise in Microsoft Access culminated in a strong grasp of data manipulation techniques critical for business analysis.
