12.4 Summary


Data management on small MIDP devices is largely a design issue. For most simple MIDlets, it is probably best to have developers come up with their own data storage and management schemes using standard RMS record stores. That is both cheap and fast for small projects. However, for many complex enterprise applications, using existing toolkits could help increase developer productivity in the long run. In this chapter, we went through MIDP data management toolkits provided by three leading vendors and learned about their use. The notable features of each solution are as follows.

The PointBase Micro Edition provides a set of JDBC-like and easy-to-learn APIs. However, it is relatively large and is slow on the smallest phone devices.

The Oracle SODA is a Java-centric solution and integrates well with Java applications. However, the API is proprietary. Multiple abstractions could make it slow when there is a large amount of data.

The IBM DB2e FastRecordStore is a thin wrapper over RMS record store. It has very good performance and flexibility. FastRecordStore also synchronizes with IBM backend databases, a huge plus. However, the low-level API is difficult to use.


Now you can design the best mobile data management strategy based on the solutions given in this chapter.
