+Introduction / System Overview:
+This project revolves around the design and implementation of an employee management
+system web application that is composed of two sub-components: employee payroll
+management and employee performance management. These sub-components and the system
+as whole assist organizations and companies in the processes of evaluating and tracking
+employee performance relative to a particular product or project and performing
+payroll-related activities (i.e., calculation of gross wages, deductions, net pay, and generating
+the pay stub).
+To accommodate the time constraint imposed on this project, certain assumptions regarding
+the scope of the system's functionalities were made:
+● The performance of each employee is evaluated per project/product.
+○ KPIs will be based on the project/product type.
+● Each employee will be paid bi-monthly.
+○ The payment cycle date is fixed and common for all employees in the
+organization. This assumption is valid as it reflects general accounting
+principles.
+● Each employee will have a fixed wage.
+User Experience / User Interface:
+To utilize the functionalities of the system, users will have to initially register an organization
+in the web application and create departments. Following the latter, the superuser (the user
+who created the organization) can then invite other users (i.e., employees) to join newly
+created departments. Certain departments, as well as users with the appropriate access level,
+can create projects, set payroll details, and enter performance appraisal results into the system
+via forms in the web application. Additionally, the employees can also download their pay
+stubs or their appraisal results as a PDF.
+Entities:
+To provide and support the functionalities discussed above, the employee management
+system will be composed of the following entities:
+● Organization: (Strong)
+○ Creating an organization entity is the entry point to our system. It will contain
+basic details about the organization, such as the business registration and
+payment cycle information. The attributes of this entity, such as the
+payroll/payment cycle date, are important for the payroll management
+functionalities as they determine when and how much each employee will be
+paid.

+● Employee (Weak)
+○ This entity contains information about each employee of an organization,
+including the bank and wage details. This information will be available for the
+employee themselves to be accessed when necessary.
+● Bank: (Weak)
+○ This entity contains the bank details (e.g., branch number, account number,
+and bank name) of each employee. Although this entity is not accessed by any
+other entity, its information is used in the computation and entry of records
+into the payroll entity.
+● Payroll: (Weak)
+○ This entity consists of details such as the hours worked by an employee, their
+gross pay, and any applicable deductions required for calculating their net pay
+and generating the pay stub. The latter is made possible by this entity's
+relationship with the employee and organization entity.
+● Performance: (Weak)
+○ Whenever an employee in the organization has their performance evaluated,
+the results are stored in this entity. This entity is dependent on information
+from the employee and project entity. Users can access information from this
+entity by viewing their performance results/evaluation.
+● Product/Project: (Weak)
+○ This entity contains unique information about each product/project that is
+being undertaken by the organization and its employees. Additionally, the
+evaluation of employees' performance is done using key performance
+indicators (“KPIs”) relative to the product/projects category. It aids in
+managing expectations from which employee appraisals will be entered into
+the performance table according to each project or product ID.
+● Department: (Weak)
+○ This entity contains information regarding the different departments within the
+organization, the number of employees per department, as well the
+description, budget, and access scope of each department. Employees' access
+levels are based on the department entity they are associated with.
+Relationships:
+1. Employee → Department
+a. A department can manage multiple employees.
+b. One employee will be managed by one department (1:N relationship)
+2. Employee → Position
+a. An employee can have one position
+b. Multiple Employees can have the same Position (1:N relationship)
+3. Employee → Bank
+a. Each employee has one bank ID
+b. A single bank ID will belong to one employee (1:1 relationship).

+4. Employee → Payroll
+a. Each employee will be submitted to one payroll
+b. One payroll will be submitted by one employee (1:1 relationship)
+5. Employee → Performance
+a. Each employee can have multiple records in the performance entity (1:N
+relationship)
+b. One performance record can only belong to one employee ID (1:1
+relationship)
+6. Performance → Product/project
+a. Each project will have multiple performance reports (one per employee) (1:N
+relationship)
+b. Each performance entity record will have one project associated with it.
+Performance → Employee (1:1 relationship)
+7. Organization → Payroll
+a. Each organization will be part of one payroll.
+b. One payroll will be part of a single organization (1:1 relationship)
+8. Department → Product/project
+a. One department controls many projects.
+b. Many projects can be controlled by one department (1:N relationship)
