A method for storing data in an electronic device, using tags to mark events carried out in the electronic device during a certain time period. The method involves defining a tag which is assignable to data related to events which are carried out and stored using the electronic device; defining a time period for using the tag; and configuring the electronic device to assign the tag to data related to all events stored using the electronic device during said time period. The tag may be used for all events of only one type, such as pictures captured using a digital camera. Alternatively, the tags may be used for a plurality of types of events, such as for captured pictures or videos, received virtual business cards, calls dialed or received, messages sent or received, and so on. Data associated with an event related to a certain occasion may then be searched and accessed using a tag register.
