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.

The impact of the MIT-BIH Arrhythmia Database
IEEE Engineering in Medicine and Biology Magazine, 2001The MIT-BIH Arrhythmia Database was the first generally available set of standard test material for evaluation of arrhythmia detectors, and it has been used for that purpose as well as for basic research into cardiac dynamics at about 500 sites worldwide

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

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.

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 ...

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.

Blockchain-based Database to Ensure Data Integrity in Cloud Computing Environments
2020 International Conference on Mainstreaming Block Chain Implementation (ICOMBI), 2020Data is nowadays an invaluable resource; indeed, it guides all business decisions in most of the computer-aided human activities. Threats to data integrity are thus of paramount relevance, as tampering with data may maliciously affect crucial business ...

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

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.
