Classical distributed database systems monolithically offer distribution transparency and higher performance. With the advances in technologies this monolithic approach is insufficient. In the new computational environment data distribution issue has been evolved to the data integration from heterogeneous data sources. Multidatabases are designed to allow timely and reliable access to large amount of heterogeneous and autonomous data sources in an environment that is characterized as “sometime, somewhere.” However, the concept of mobility, has introduced additional complexities and restrictions in a multidatabase system. These include: A reduced capacity network connection, processing and resource restrictions, and effectively locating and accessing information from a multitude of sources.

An extended multidatabase system (MDBS) that facilitates “anytime, anywhere” access to the information is called a mobile data access system (MDAS). Within the scope of MDAS, we distinguish three classes of services:

     • Broadcast based services,
     • On-demand based services, and
     • Pervasive based services.

Within the scope of broadcasting, we introduce and evaluate algorithms that address:

     • Data allocation and retrieval on single and parallel channels,
     • Application of indexing on the air channel (s),
     • Access conflict and conflict resolution, and
     • Power management,

Within the scope of on-demand services with regard to the technological limitations, we introduce and analyze solutions that address:

     • Query processing, location dependent, location aware, and continuous queries,
     • Application of mobile agents,
     • Multimedia data processing,
     • Transaction processing,   
     • Power management,
     • Ad Hoc network,
     • Caching, and
     • Security
