An HR information system (HRIS) is a comprehensive software application that streamlines and manages human resources-related data and processes within an organization. It serves as a centralized repository for employee information, automates routine HR tasks, and supports decision-making by providing real-time data and analytics.

Example
A company uses an HRIS to maintain a digital database of employee profiles, track attendance and leave, manage payroll, and generate reports on workforce trends and performance metrics.
