Create “Employees Database” using MS-Access. Make relevant assumptions for designing the database.

To create an "Employees Database" using MS-Access, we'll need to design the database schema that captures relevant information about employees. Here are the assumptions and design considerations for the database:

1. Employee Information:

   • Employee ID: Unique identifier for each employee (Primary Key).
   • First Name and Last Name: Fields to store the employee's name.
   • Date of Birth: Field to store the employee's date of birth.
   • Gender: Field to store the employee's gender.
   • Contact Information: Fields for storing email address, phone number, and address.

2. Employment Details:

   • Department: Field to store the department in which the employee works.
   • Designation: Field to store the employee's job title or designation.
   • Date of Joining: Field to store the date when the employee joined the company.
   • Salary: Field to store the employee's salary information.

3. Additional Information:

   • Manager ID: Field to establish hierarchical relationships between employees, where each employee may have a manager.
   • Employee Status: Field to indicate whether the employee is active, on leave, or terminated.
   • Employee Skills: Fields to store information about the skills possessed by the employee.

4. Assumptions:

   • Each employee has a unique employee ID.
   • Employees may belong to different departments.
   • Each department may have multiple employees, but an employee belongs to only one department.
   • Employees may report to a manager, identified by the manager's employee ID.
   • The database will store historical employee data, including past and present employees.
   • Access rights and security measures will be implemented to ensure data privacy and integrity.

Using MS-Access, we can create a table for each entity (e.g., Employees, Departments) and establish relationships between tables using foreign keys. We can define appropriate data types for each field, enforce constraints (such as uniqueness and referential integrity), and create forms, queries, and reports for easy data manipulation and analysis.

By designing the "Employees Database" in MS-Access with the above considerations and assumptions, we can effectively store and manage employee information, facilitating HR operations, reporting, and decision-making processes within the organization.
