# SQL_Project:
Here, I performed a comprehensive analysis of the employee status within an organization. This process involved the following key steps:
1) Database Creation: Designed and structured a database to accurately represent the organizational hierarchy and employee details.
2) Data Entry: Entered relevant data into the respective tables, ensuring accuracy and consistency across all records.
3) Query Execution: Formulated and executed SQL queries to answer a series of predefined questions about the organization’s employees. These queries provided valuable insights into various aspects of the workforce, such as demographics, performance metrics, and departmental distribution.
# Structure of Database:
The database are related to a E-commerce company and the Database Schemas are-
- Employee : Stores employee details
- Department : Stores department details of employees
- Dept_locations : Stores department locations
- Project : Stores details of projects employees are working on
- Works_on : Stores working hours and other details of employees
# The questions I wanted to answer through my SQL queries were:
- Major Question 1
A) List the salary of all the employees.
B) Display the names of all employees with any “A” at any place of the name.
C) Show all employees who were hired in the first half of the month (Before the 16th of the month).
D) Display the name of all female employees.
E) Display the employee who is paid most in the company.
- Major Question 2
A) Display employee name, address, department no and department name.
B) Display all the employees who are not in ACADEMIC department.
C) Display SATYA’S project location.
D) Find the total working hours of each female employee.
E) Display the details of the people whose projects are located at SOUTH AFRICA.
# Tools I Used:
- SQL: The backbone of my analysis, allowing me to query the database and unearth critical insights.
- MySQL: The chosen database management system, ideal for handling the job posting data.
