Abstract

A method and system for synchronizing and using calendar information from a shared database is disclosed. Calendar information can be stored in a shared database, e.g., on a server system and accessed and synchronized with one or more portable computer systems. The calendar information is stored using particular category types which facilitate separate manipulation, access and removal of the calendar information when placed onto a portable computer system (e.g., palmtop). In one embodiment, calendar information is stored on a shared database and is assigned a unique category type. Multiple portable computer systems can then access the shared calendar information which can be displayed on each computer system along with the system'"'"'s own calendar information. The unique category type is different from the default type of each system'"'"'s own calendar information and the user is not able to change category types on the portable computer system. Shared calendar information can be viewed and edited and then easily removed using the unique category type.

Claims

1. A method of processing information comprising:

storing first and second calendar information, respectively, under first and second category names, said first and second calendar information stored in a database on a server, said database comprising calendar information received from multiple computer systems, said first calendar information corresponding to a first portable computer system and said second calendar information corresponding to a second portable computer system;

displaying said first calendar information in conjunction with said second calendar information, such that events in the first and second calendar information are combined in a single listing of events over a duration; and

synchronizing said first calendar information in said database but not said second calendar information with calendar information of said first category name stored on said first portable computer system via delta records wherein modifications to said first calendar information in said database are reflected in said first portable computer system and modifications to said first portable computer system in said database are reflected in said first calendar information, wherein said delta records represent changes in said database.

2. The method of claim 1, further comprising synchronizing said second calendar information in said database but not said first calendar information with calendar information of said second category name stored on said second portable computer system wherein modifications in said database are reflected in said second portable computer system and modifications in said second portable computer system are reflected in said database.

3. The method of claim 1, further comprising synchronizing a third calendar information in said database but not said first and second calendar information with calendar information of a third category name stored on a third portable computer system wherein modifications in said database are reflected in said third portable computer system and modifications in said third portable computer system are reflected in said database.

4. The method of claim 1, further comprising modifying a portion of said first calendar information.

5. The method of claim 1, wherein said first portable computer system is a handheld computer system.

6. The method of claim 1, wherein said second portable computer system is a handheld computer system.

7. The method of claim 3, wherein said third portable computer system is a handheld computer system.
