But there are also many times when we need to ignore the theory and build practical solutions.

Journal of the ACM, 1984
ABSTRACT This paper concerns the semantics of Codd's relational model of data. Formulated are precise conditions that should be satisfied in a semantically meaningful extension of the usual relational operators, such as projection, selection, union, and join, from operators on relations to operators on tables with “null values” of various kinds ...

Fingerprinting relational databases

Proceedings of the 2006 ACM symposium on Applied computing, 2006
In this paper, we propose a fingerprinting solution to protect valuable numeric relational data from illegal duplications and redistributions. We introduce a twice-embedding scheme. In the first embedding process, we embed a unique fingerprint to identify each recipient to whom the relational data is distributed.

Publisher Summary This chapter discusses the different aspects of relational databases. Relational databases derive their power from the simplicity of their underlying concepts.
