Project Description

Consider modelling certain features of an application for storing and organising digital photographs. Each photo has an identifier, as well as a date and time when the photo was taken and a location where the photo was taken. Photo may be of one or more people, each of whom has a name. Photos can be organised in two different ways. One is in terms of events, which might be something like "Holiday in Italy". The other is in terms of albums. Both events and albums have titles, but whereas each photo can be part of only one event, each photo can be included in any number of albums.

Draw an entity-relationship diagram that models the above description. Make sure that you specify all details in the diagram, including cardinality (mapping) constraints, participation constraints, keys. etc. Please use the ERD notation . Submit a file containing your diagram
