Epistemological aspects of object schemes Academic Article uri icon

abstract

  • There is an increasing demand on database management systems to support nontraditional applications such as computer aided design (CAD) and decision support systems (DSS), which deal with complex objects. Complex objects are objects that have nonatomic components (unlike the traditional relational model). Many researchers have designed object systems to support complex objects. Five levels of scheme representations are identified in the paper-they are: 1) record-structure level (lowest), 2) relational level, 3) logical level, 4) semantic level, and 5) object level (highest). Different object schemes proposed in the literature differ in their levels of representation. The paper motivates the need for a formalism for the object level of representation, and it describes a formalism for an object scheme called NEXUS. © 1992 IEEE
