Abstract:
This work presents the design and implementation of a system of representation and recovery of incomplete data and temporal information (RADINT). Initially, we introduce basic concepts and then analyze details of system implementation. A framework for representing incomplete data in the Relational Database is proposed. We also investigate problems related to incomplete data processing. The main aspects considered in the project are incomplete data, marked or unmarked null values, conditional facts, fuzzy values. All of these issues were included in the system implementation. We emphasized temporal aspects such as periods and intervals. Also, we distinguish three types of incomplete data such as: Negative, Unknown and Inaccurate. We present several forms of representation and recovery of incomplete data. What's more, the system has the ability to deduce and respond to recovery queries and Boolean queries such as "YE5", "NO", "UNKNOWN" and "P0SSIBLE".
