Symbian’s Internal Database, EDBMS, strikes a balance between functionality and small footprint, letting you create database apps that run without alteration across diverse mobile devices.
Dr.Dobb’s Portal has an in-depth article which discusses EDBMS and deals with such issues as limitations, physical implementation, retrieving and managing data, indexes, datatypes, client-side access and more. Good read.
A Java API for the Sedna XML Database exists and can be used on any Symbian OS, the API is very practical at under 50k in size. The Database itself supports storage and querying (XQuery) of both XML documents and binary objects (e.g. Java Object Storage).
