Summary: | Approved for public release; distribution unlimited === The overall objective for distributed databases is that of
sharing of data among several nodes. Increasing the number of
users and the size of communication are two factors associated
with distributed database systems. These factors, with others
such as hardware, software and operations, are major factors
which could originate threats to the distributed database
integrity. Some discussion about these factors is presented.
Maintaining the data integrity has become a critical problem in distributed database fields. The problem requires
a clear and precise view; it needs an early determination for
meeting user requirements for integrity, since each organization
has its own priorities.
This thesis examines integrity in general and presents
some considerations and strategies to be spaced through
different system levels, such as design, management, and
operation and communication. The main idea of such approaches
is to avoid the threats, or to reduce the risks.
