Semantic Shortcomings of Database Management Systems Based on a Relational Model

Abstract

To many critics and researchers, semantic meagerness is the main limitation of relational database management systems. The burden placed on users to remember attribute names and their domains is discussed and difficulties associated with the lack of set as a type for an attribute is examined. This thesis explores the implications to high-level query languages necessitated by a set-type attribute. The allowance of semantically improper joins by DBMS is studied as is the lack of strong data type checking. The semantic shortcomings of system-chosen access paths is discussed. These problems are followed by recommended solutions.
