Retrieving the agenda information of telephone based on symbian OS

The agenda database file, stored in the telephony, is rich of personal information. Analyzing and extracting the useable clues is very significant for case-investigation and evidence-gaining. First of all, it is necessary to analyze the data structure of the database files and retrieve the information. In this paper, I find out the data structure of agenda files, on the IDE-- Carbide C++ developed by Nokia in use of database API (application program interface), which is provided by SDK (software development kit) of Carbide C++. And I test the program on the N90.At last, I get a good result.
