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.

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.

ACM SIGMIS Database: the DATABASE for Advances in Information Systems, 1983
This paper summarizes a study conducted by the authors which investigated methodologies presently available to assist in the process of database design. The study also examined the current status of database design in a variety of organizations (manufacturing, financial government, service, and other).

This chapter does not just deal with creating databases, tables, and querying them. It also deals with setting your database up in your Docker environment, which is a technical aspect of database knowledge that you should have.

Journal of Automated Reasoning, 1988
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.

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.

Security is an important issue that must be considered as a fundamental requirement in information systems development, and particularly in database design. Therefore security, as a further quality property of software, must be tackled at all stages of the development.

Information Systems, 1985
Abstract This paper proposes a database management system that automatically executes and integrates data retrieval, information deduction and information processing for query processing. The major thesis is that a user should be allowed to define and access any information related to a database—even if the information is not explicitly stored in the

A database design for graphical models
ACM SIGPLAN Notices, 1990In this paper we present an engineering data management system, that is a database which is supposed to store and support the manipulation of data about solid geometry objects. Some technical aspects are particularly addressed, which are related to the modeling environment, system architecture and data manipulation language.
