The goal was to assist the Chinook team in better understanding their media inventory, customers, employees, and invoice data.\n\nI used SQLite to create a series of queries exploring various aspects of the database. Additionally, I generated charts and visualizations using Microsoft Excel and PowerPoint to present the findings clearly.\n\nAnalysis Overview\nThe Chinook Database simulates a digital music store environment. This analysis involved writing SQL queries to extract insights on:\n\nMedia inventory (albums, tracks, genres)\n\nCustomer demographics and purchasing behavior\n\nEmployee roles and sales performance\n\nInvoice and payment data analysis\n\nTechnologies Used\nSQLite (for querying the Chinook Database)\n\nMicrosoft Excel (for data visualization)\n\nMicrosoft PowerPoint (for presenting charts and summaries)\n\nHow to Run the Queries\nDownload the Chinook Database file (Chinook_Sqlite.sqlite or similar).\n\nOpen the database with an SQLite client (such as DB Browser for SQLite).\n\nOpen the SQL query files included in this repository.\n\nExecute the queries to see results.\n\nUse the outputs to generate charts or reports as needed.\n\nSample Queries\nHere are examples of the types of queries written:\n\nRetrieve total sales by customer\n\nList top-selling tracks and albums\n\nAnalyze sales performance by employee\n\nExplore invoice totals over time\n\nVisualizations\nVisual representations of the query results were created in Microsoft Excel and compiled into PowerPoint slides to illustrate trends and key findings.\n\nRepository Structure\n/SQL-Database-Analysis\n│\n├── /queries\n│   ├── customer_sales.sql\n│   ├── top_tracks.sql\n│   └── employee_performance.sql\n│\n├── /visualizations\n│   ├── sales_charts.xlsx\n│   └── presentation.pptx\n│\n└── README.md\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpatricialjohnson%2Fsql-database-analysis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpatricialjohnson%2Fsql-database-analysis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpatricialjohnson%2Fsql-database-analysis/lists"}
