Well, someone can decide by themselves what they want to do and need to do but sometimes, that kind of person will need some the nested universal relation database model references. People with open minded will always try to seek for the new things and information from many sources. On the contrary, people with closed mind will always think.
Nested relations generalize flat relations and allow hierarchically structured objects to be modelled directly, whereas the classical UR model allows the user to view the database as if it were composed of a single flat relation. The author presents a comprehensive formalisation of the nested relational model, which incorporated null values into the model. Functional data dependencies and the classical notion of lossless decomposition are extended to nested relations and an extended chase procedure is defined to test the satisfaction of the data dependencies.
To achieve this, the nested UR (universal relation) model is defined by extending the classical UR model to. .

Lecture Notes in Computer Science is a series of computer science books published by Springer Science+Business Media since 1973. In addition, tutorials, state-of-the-art surveys, and "hot topics" are increasingly being included. Two sub-series are: Lecture Notes in Artificial Intelligence. Lecture Notes in Bioinformatics. Monographiae Biologicae, another monograph series published by Springer Science+Business Media.
