Moving object databases allow to store and query the objects, which change their
position in time. They also may change their position and their extent in time.
The time-dependent data can be represented in several different ways. The moving
object databases may be useful for storing data (for example, trajectories of
movements of objects) from different security and surveillance systems. Data may
be also queried later. Not only for these cases, it is needed to process data as
quickly as possible. This paper deals with comparing the performance of an
extensible database system named Secondo, which uses Berkeley DB as a storage
manager, and an application programming interface named VTApi, which uses
database system PostgreSQL as a storage manager. The paper provides some basic
information about Secondo system and about VTApi interface. It also presents
a selection of test data, describes them briefly and provides information about
their adjustments for testing purposes. Paper presents selected methods for
performance testing and their results. Finally, the results are discussed and the
proposals of future directions are mentioned.
