Abstract. In recent years the deployment of embedded systems has
increased dramatically, e.g. in the domains of sensor networks or ubiqui-
tous computing. At the same time the amount of data that have to be
managed by embedded systems is growing rapidly. For this reason an ad-
equate data management support is urgently needed. Current database
technologies are not able to cope with the requirements specific to embed-
ded environments. Especially the extreme resource constraints and the
diversity of hardware plattforms and operating systems are challenging.
To overcome this tension we argue that embedded database functionality
has to be tailored to the application scenario as well as to the target plat-
form. This reduces the resource consumption and customizes the data
management to the characteristices of the plattform and the application
scenarion. We show that component techniques and feature-oriented pro-
gramming help to face the mentioned limitations without focusing on
