碩士 === 國立成功大學 === 製造工程研究所 === 86 === The diversifying redundancy, as a strategy for enhancing
software reliability, has been proposed, tested, and acclaimed
effective.
Nevertheless, a close-up examination reveals the dismal lack of
real world applications.
To put an end to the aforementioned disparity and pinpoint the
frontier of reliability-enhanced software development, this
thesis addressed implementation issues of raising database
reliability by adopting the diversifying redundancy strategy. It
has analyzed, in addition to the system framework, technical
feasibility issues that support the employment of diversifying
redundancy strategy to achieve a reliability-enhanced database
(RED). The time
is now for developing the low-cost RED.
In this thesis we focus on issues of raising the reliability of
database systems, and propose the RED system.
While an individual database management system (DBMS) enjoys low
maintenance requirement, it suffers from having low reliability
and availability.
On the other hand, the distributed database management system
(DDBMS) achieves medium reliability and availability at the cost
of high maintenance requirement.
Therefore, the RED system is expected to out perform both DBMS
and DDBMS in reliability.
The framework of RED, which offers the capacity of succinct
specification and unmistakable description of a particular
system, is investigated and its representation is proposed.
For implementation considerations, first we present, in addition
to addressing requirements for RED transactions, independent
database management systems available on the market.
Then, we review the statistical test of outputs independence
before exploring a new test of failures independence.
The independence test of failures is the only test available to
date for the stated purpose.
