A master file holds information temporarily so that it can be used to update other master files.

Most object-oriented programming languages support sequential and random access files.

Finding a specific object in a sequential access file is relatively easy to do.

An object-relational database is used primarily to support multimedia applications.

Complex data stored as objects will be manipulated slower than with other storage formats.

It is likely easier today to find expertise in OODBMS than in RDBMS.

Mapping between the problem domain objects and an OODBMS is a straightforward oneto- one mapping.

Mapping from the problem domain to the data management objects in an RDBMS format is a straightforward one-to-one mapping

In terms of storage space, the most efficient tables in a relational database have redundant data and many null values.

Update anomalies occur when some instances of redundantly stored data are overlooked when an update occurs.
