## Project Overview



Excelsior Mobile is a small mobile company looking to expand its customer base. As a business analyst, your task is to analyze their customer database and provide insights to guide marketing efforts and make data-driven decisions.



The project is divided into several sections, with each section containing specific tasks related to data analysis and visualization. 

You'll be working with SQL queries to extract data from the database and create visualizations in Excel to present your findings.



## Database Information



Before you start, it's essential to understand the terms and tables in the Excelsior Mobile database:



- **MIN (Mobile Identification Number):** A unique number assigned by the wireless service provider (account #).

- **MDN (Mobile Directory Number):** The phone number.

- **IMEI (International Mobile Equipment Identity):** A unique number for identifying a device on a mobile network (like a vehicle's VIN).



There are six tables in the Excelsior Mobile database:



1. **Subscriber:** Contains subscriber information, including address, MDN, and MIN.

2. **Device:** Stores information about the devices used at Excelsior Mobile and has IMEI.

3. **DirNums:** Identifies the city and state of each MDN and connects it with an IMEI.

4. **MPlan:** Contains data about mobile plans, including data, throttle, and cost.

5. **Bill:** Contains information about the current bills for each MIN, including bill costs.

6. **LastMonthUsage:** Stores data about the last month of usage for each MIN, including minutes, data in MB, and texts.
