An information system (IS) is defined as the organized combination of people, hardware, software, communication networks, and data resources that collects, stores, processes, transforms, displays, transmits disseminates and disposes information in accordance with defined procedures.

  • Disposition: the act or means of getting rid of something.
  • Dissemination: the distribution of information broadly.
  • Processing: the manipulation of data in accordance with established instructions, manually or by computer. Processing by computer is the manipulation of data in accordance with its instructions, or programming.
  • Transmission: the process of sending information from one point to another.

An IS may be automated (e.g., a computerized information system) or manual (e.g., a library’s card catalog).

Any IS is made of 6 components: hardware, software, data/database, network, policies and procedures and people.

An Information System (IS) consists of six components, namely:

  1. Humans, which consists of IT specialists (such as a Database Administrator or Network Engineer) and end-users (such as doctors, nurses, etc…).
  2. Hardware, which consists of all the physical aspects of an information system, ranging from peripherals to computer parts and servers.
  3. Software, which consists of System Software, Application Software and Utility Software.
  4. Networks, which consists of communication media and network support.
  5. Data, which consists of all the knowledge and databases in the IS.
  6. Policies and procedures that governs the utilization, use and management of the information system.

without comments


Time and attendance software is a computerized information system used by organizations to effectively and efficiently manage employees work time.  It collects employee time data and enters the information into a database. The collected data is reviewed and approved by a supervisor so it can be used for payroll processing and custom reports.

The System:

  • Accurately captures and monitors real-time employee data;
  • Enforces work rules and regulations;
  • Eliminates buddy-punching;
  • Provides payroll with accurate information (interfacing vs. integrating); Transfers the hours worked, overtime, department, holidays, sick time, and vacation time;

  • Collects exceptions defined within the payroll rule assigned to each employee;
  • Enables supervisors to view exceptions by employee in a calendar format;
  • Provide comprehensive employee statistics, from badge listings to overtime calculations;
  • Schedules can handle organization’s full range of conditions;
  • Schedules conform to relevant government requirements


  • Accurate Tracking. A time and attendance system automates the process of tracking employees as they check in and out for work leading to accurate time data for each employee and fewer payroll processing errors (effectiveness).
  • Increased Efficiency. Time and attendance systems enable managers to monitor employee hours in real-time, track hours, unauthorized overtime, and create detailed reports about individual employees.
