Team project for data-driven business with SQL and Tableau.\n\n## Project\n\nEniac is a online marketplace specializing in Apple-compatible accessories. To enter the Brazilian market, Eniac is considering a partnership with Magist, a Brazilian company that offers a centralized order management system to connect small and medium-sized stores with the biggest Brazilian marketplaces.\n\nTo help Eniac make an educated decision, two questions are at the core of this project.\n\n1. Is Magist a good partner for high-end tech products?\n2. Is Magist's delivery service fast enough?\n\nWe found that Magist represents a small tech sector and provides delivery services subpar to Eniac's expectations. Based on the provided data, we therefore do not recommend Magist as a partner at this time.\n\n[![Tableau visualization preview](TableauVisualizationPreview.png)](https://public.tableau.com/views/MagistAnalysis_17146788675680/Recommendation)\n\n\u003e [!TIP]\n\u003e Click on the preview to interact with the published Tableau dashboard\n\n## Languages and libraries used\n\n- SQL (with MySQL)\n- Tableau Public\n\n## Key learning\n\n- Explore the undocumented relational database describing Magist's services\n- Join and query the database tables to extract and filter relevant information about Magist's performance\n- Agree on various approaches and divide the tasks among the team\n- Clean the data and identify outliers\n- Visualize the key findings using Tableau\n- Research the Brazilian market and put the data into context\n- Compile the insights across team members in a cohesive way to reach a conclusion\n- Present the findings and make a recommendation for Eniac\n\n## Challenges overcome\n\n- Understanding the undocumented database\n- Establishing a definition for high-tech products based on product categories\n- Working with a data in a foreign language (specifically customer reviews in Portuguese)\n- Identifying the strongest findings and stripping irrelevant insights\n- Presenting the results in a concise manner to meet time restrictions\n\n## Resources\n\n### Analytics\n\n- [Schema.pdf](Schema.pdf) - Schema of the relational database\n- [Revenue.sql](Revenue.sql) - Query to extract the revenue information\n- [Delivery.sql](Delivery.sql) - Query to extract the delivery times\n- [Reviews.sql](Reviews.sql) - Query to extract the customer complaints\n\n### Visualization\n\n- [MagistAnalysis.twbx](MagistAnalysis.twbx) - Tableau Public Dashboard\n- [Published Tableau Public Dashboard](https://public.tableau.com/views/MagistAnalysis_17146788675680/Recommendation)\n- [Presentation.pdf](Presentation.pdf) - Project presentation including the final recommendation\n\nTableau Public Dashboard link  \nhttps://public.tableau.com/views/MagistAnalysis_17146788675680/Recommendation\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fszapp%2Fmagistdataanalysisvisualization","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fszapp%2Fmagistdataanalysisvisualization","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fszapp%2Fmagistdataanalysisvisualization/lists"}
