The future of DBMS

Overview n n What is DBMS now How DBMS was viewed before Current trends and developments Future directions of research

What is DBMS? Wikepedia definition of DBMS: (1) Is a set of programs that enables you to store, modify, and extract information from a database, it also provides users with tools to add, delete, access, modify, and analyze data stored in one location; (2) Active research area; (3) A multibillion dollar business.

Old DBMS n Old DBMS: n n n Stand-alone, Static, non-interactive, Very limited representing interaction between objects, Confusing set of data models, Independent application

Current DBMS Parallel n Distributed n Information visualization + HCI support n Capable of learning and supporting decisionmaking process n Enabling n Supports transition: data->information ->knowledge->wisdom n

Motivation n n Organizations are relying less on their own data automation and more on sharing. Portability of the data is a key component to finding and evaluating data and facilitating data transfer. New data models / structures emerge to better represent different phenomena. Extremely large data set problem becoming a crucial one. Security and privacy play pivotal role.

Trends in data storage Society is collecting and storing more information in a digital form There is better access to information for everyone, both within organizations and outside organizations (i. e. public access)

Trends in Integrated systems n n New query languages New inter-related systems New interfaces Extensive set of tools for data analysis, query and representation

Trends in web searching n n n Graphic searchers Multimedia database New methods for information similarity Adaptive learning Data mining

Trends in on-line search n n n User behavioral patterns Visual context Social profiles Multiple contexts User preference/profiling

Trends in privacy and security n n Encryption Combination of different security mechanisms Data privacy Policies in addition to backup/recovery

Future trends n n n Integration (multiple formats, multiple databases) Accessibility (anytime, anywhere) Reliability (no data loss) Proper display of data (advanced graphics methods) Real-time access

Future trends n n n Real-time decision support Information visualization and 3 D modeling Tracking DB development on-line Data exchange between different applications/vendors Virtual and augmented reality Intelligent Decision support and cognitive methods for data analysis

Future Interfaces n n n n n Scientific visualization tools Automated vision tools Fourth dimension Advanced spatial analysis tools (e. g. S+) Beyond the WIMP (windows, icons, menus and pointers) Desktop High Interactivity Multisensory input Multisensory output Touch free displays
