This paper presents the fundamental theory of multi-level concurrency control and recovery. A model for the computation of multi-level transactions is introduced by generalizing from the well known single-l

Cell Cycle Deregulation in Cancerguage of a relational database management system. IID extends the traditional roles of a data dictionary by enabling a user to view, manipulate, and verify semantic aspects of relational data. Our use of IID focuses on the interactive creation of simulation-specific databases from large "public" dat

Strong constraints on the design of a common model are exercised by the need to interface well with object models in programming languages, and the desirability of a smooth evolution from existing database technology..This paper briefly reviews some salient features of database and langu

Cell Cycle Deregulation in Cancerhere have been many different suggestions as to how to implement a UR interface. Nested relations have been recently suggested as a way of extending the applicability of the classical relational model. In this paper we establish a strong connection between the UR model and nested relations. Thus, ne

We present an extension of the method, where the trie is split into subtries stored each in a page on the disk. Address computation requires the core for a single page. Two disk accesses may
