On the design of replicated databases
Information Sciences, 1992Abstract Providing data availability is a prime consideration in database systems. Replication is a natural paradigm to increase the data availability in distributed databases. In this paper we focus on how to allocate the copies of a replicated database system to increase its fault tolerance.

ACM Transactions on Database Systems, 1981
The security problem of a statistical database is to limit the use of the database so that no sequence of statistical queries is sufficient to deduce confidential or private information. In this paper it is suggested that the problem be investigated at the conceptual data model level.

We consider the problem of designing schemas for deductive databases. The design problem is to construct a database schema that supports, at minimal expected cost, a given set of database transactions. Our results include a formal definition of both a deductive database schema and a schema transformation.

The Linguistic Design of the EuroWordNet Database [PDF]
Computers and the Humanities, 1998 In this paper the linguistic design of the database under construction within the EuroWordNet project is described. This is mainly structured along the same lines as the Princeton Word-Net, although some changes have been made to the WordNet overall design due to both theoretical and practical reasons.

Some database systems textbooks make much ado about having separate chapters for database modeling and database design. In this course, we will not, and the reason will become clear shortly. All discussions in chapters 3 and 4 contribute to database modeling and design. In particular, ERDs and normalization are paramount to a logical database model and

Data collected for audit comes in all shapes and sizes. It will depend very much on the planned project. There may be numeric data (percentages, test results, ages etc.); textual data (names, addresses, drugs and drug regimens, comments etc.); codes (ICD9, OPCS4, READ etc.); dates (date of birth, admission, discharge, date of last test etc.); true or ...

Evidence-based medicine has always relied on databases. Anyone who needs to know anything about the outcome of a treatment needs a database, but individual practitioners may feel that database design is beyond them for various reasons. Effective database design does not require complexity.

The American Journal of Occupational Therapy, 1991
Abstract Computerized databases can facilitate several types of occupational therapy research. The value and usefulness of any database, however, is dependent on how well it has been designed. In this paper, a systematic, sequential-process model for the development of a computerized database is introduced. Each component of the model is

Physical database design for relational databases
ACM Transactions on Database Systems, 1988This paper describes the concepts used in the implementation of DBDSGN, an experimental physical design tool for relational databases developed at the IBM San Jose Research Laboratory. Given a workload for System R (consisting of a set of SQL statements and their execution frequencies), DBDSGN suggests physical configurations for efficient performance.

A framework of reference for database design
ACM SIGMIS Database: the DATABASE for Advances in Information Systems, 1984This work introduces a framework of reference for database design.Database (DB) design is presented as a part of information system (IS) design, because the DB design process is concerned with the construction of a database as a subsystem of an IS.
