5. Information System
Information systems are systems which provide information to users. The term "information system" would normally refer to a computer based system using a DBMS.
A DBMS is a program which creates and manages a database.
A database is the file that is then created by a DBMS.
Database Management System (DBMS) is a software that enables a database to be created, edited and maintained as well as to be stored and searched to extract information

8. Components Of Information System
Environment – Everything that is influenced by the Information System
Purpose – For what need & whom is the information system designed
Information Systems – Users, individuals, IDPO, computerised & non-computerised
Information Processes – Computerised such as access the internet & non-computerised such as listening to the news
Participants – People who carry out information processes with the information system
Date/Information – Raw materials of information going in & coming out as processed data I/O
Information Technology – Hardware & software used by the information processes

9. Example of a System Braking system of a car
The Purpose is to slow the car down
Braking system requires resources or components such as brake pads, break disks, brake pedal
Components work together to process/make the car slow down
The Environment is everything that is influenced by the system

10. Diagrammatic Representation of a System
Environment – The Car, Including all its various sub-system
System – The Braking System
Purpose – To slow down the car
Processes – Pressing brake pedal, fluid moving to callipers, friction between pads and disk, wheel slowing down, etc
Resources – Brake pedal, master cylinder, callipers, brake pads and disks, wheels tyres, etc

12. Pool Filtration System
A backyard swimming pool contains a filtration system that includes a timer, a pump, a filter, various pipes and electrical connections and a skimmer box. These components work together to keep the pool water clean and healthy. Fig 2.2 shows many of these components, together with the flow of water.
