• OODBMS = object-oriented DBMS (no longer
restricted to tables; can be audio, video files,
etc.).
• ORDBMS = hybrid of OODBMS and RDBMS
(tables can support binary data like video).
• Inference = putting together pieces of
accessible data to arrive at supposedly secret
information.
• Aggregation = intelligence gathering by
combining data from lower classifications to
derive information of a higher classification.
The sensitivity of the whole is greater than the
sensitivity of individual parts.
• Data warehouse = consolidated view of
enterprise data, optimized for reporting and
analysis. It is often used with data mining.
• Datamart = more focused than a data
warehouse; is a specialized data repository for a
specific department.
• Normalize the data = getting rid of duplicates.
• Metadata = information about data.
• Lock controls = control read/write access and
ensure 1 user at a time
▪ ACID = atomicity, consistency, isolation,
durability
• Atomicity = all changes take
effect, or none do.
• Consistency = transaction only
allowed if it meets integrity
constraints.
