Decision tables

This paper proposes an efficient method to determine entire reducts of incomplete decision tables according to the relational database approach. In the complex case, this algorithm has exponential computational complexity. However, this algorithm has polynomial computational complexity in the different cases of databases.

The first is the hybrid filterwrapper algorithm proposal for finding the reduction set of the decision table using advanced fuzzy distance measurements and other measurements basing on fuzzy rough set to minimize2 the number of attributes of reduction set. Reduce and improve the accuracy of the classification model.

The research content in the thesis is the current problems which are renewed with a series of works of foreign authors; while in the country (in Vietnam), there are many published works related to methods and algorithms finding reducts of a decision table by different approaches. The objective of the thesis is to research some analyzed problems in range of relational databases.

Functional testing is a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing).[1] Functional testing differs from system testing in that functional testing "verif[ies] a program by checking it against ... design document(s) or specification(s)", while system testing "validate[s] a program by checking it against the published user or system requirements"...

Critical Database Concepts new features include “invisible” indexes, simplified table maintenance, and editioned objects. You should evaluate your previous architecture decisions in light of the new features available. In the next several chapters, you will see how to install Oracle Database 11g and how to upgrade to Oracle Database 11g from prior releases. Following those chapters, you will see an overview of application planning, followed by many chapters on the use of SQL, PL/SQL, Java, object-oriented features, and XML to get the most out of your Oracle database.
