You can use either Record Management System (RMS), go for on-device file storage or use PIM API if data to be stred are relevant to ContactList or EventList.
Resources of interest Getting Started With the PIM APIs, book Kicking Butt with MIDP and MSA (sources files for download chapter 14-16), IBM Inside the Record Management System(little old by useful) and NetBeans RMS Tutorial
