Task 2 Case Study – 30 marks
Bushfires are a widespread and regular phenomenon in Australia and have caused significant property damage and loss of both human and animal life. Several organisations are working to prevent and battle bushfires. RFS (NSW RURAL FIRE SERVICE) is a volunteer and community-based fire and emergency services organisation in NSW.
Data and Information Management plays a critical role in planning and operations of RFS. RFS has three type of Brigades including Fire Brigade, Forest Industry Brigade, and Coastguard Brigade. Each Brigade has a number of members and no one can be a member of two or more brigades. Each member is either a paid staff or a volunteer. RFS needs to keep record of staff personal details of members including name, age, gender, address, contact details, … and their location. The members work in shifts. A shift consists of start and end time. The shifts do not overlap, but they are consecutive, i.e. there is a shift on at any given time and day. We are assuming that the model we are creating (and eventually the database we will design) covers some extended period of time. Each member will thus be assigned to many shifts in that period.
RFS keeps record of its operations in the incidents including members and equipment involved, as well as the details of incident (e.g. type, location, date/time started, date time finished, …)
Stations: RFS delivers services to the community through a network of rural, urban and integrated fire stations across NSW. RFS’s fire stations are specifically designed to support and facilitate the emergency needs of the firefighters and to house our specialist vehicles and equipment.
