Overview of the course
The continuously increasing power of microprocessors and the very large capacity of modern electronic storage devices make it possible to embed Database Management Systems and the Databases themselves as inner components of larger application systems. The application areas which can mainly benefit from this technology are industrial control systems and handheld mobile computation devices including Smart cards and cellular phones. In general,
all applications that rely on Pervasive Systems can take advantage of such technology, where mobility, and the resulting need for context-awareness,
add further complexity to the typical DBMS functionalities. Due to the need to react quickly to external events, Embedded Database Systems (EDBS) are active, real-time, and mostly reside in main memory. The course imparts these notions, comparing them with the structure of a DBMS for traditional Information System management applications. The case of Pervasive Information Systems with mobile, context-aware very small databases, resident on smart
cards, PADs, cellular phone SIM cards or Wireless Sensors, is studied and examples of systems and applications are presented.

Teaching mode
Since a preliminary knowledge of Database Systems is needed in order to profit of the technical details, the first two days are devoted to an introduction to the architecture of database systems and to database design and languages.
Though this part is optional for students who are already proficient in databases, we strongly recommend attendance in order to set a common background.
