Describe the functionality required of mobile DBMS.
What will be an ideal response?
All the major DBMS vendors now offer a mobile DBMS. In fact, this development is partly
responsible for driving the current dramatic growth in sales for the major DBMS vendors. Most
vendors promote their mobile DBMS as being capable of communicating with a range of major
relational DBMSs and in providing database services that require limited computing resources to
match those currently provided by mobile devices. The additional functionality required of mobile
DBMSs includes the ability to:
? communicate with the centralized database server through modes such as wireless or Internet
access;
? replicate data on the centralized database server and mobile device;
? synchronize data on the centralized database server and mobile device;
? capture data from various sources such as the Internet;
? manage data on the mobile device;
? analyze data on a mobile device;
? create customized mobile applications.
