Tractable Circuits in Database Theory [PDF]
ACM SIGMOD RecordThis work reviews how database theory uses tractable circuit classes from knowledge compilation. We present relevant query evaluation tasks, and notions of tractable circuits. We then show how these tractable circuits can be used to address database tasks.

Database Theory + X: Database Visualization [PDF]
CoRRWe draw a connection between data modeling and visualization, namely that a visualization specification defines a mapping from database constraints to visual representations of those constraints. Using this formalism, we show how many visualization design decisions are, in fact, data modeling choices and extend data visualization from single-dataset ...

Database Theory, Yuri, and Me [PDF]
, 2010 Yuri Gurevich made many varied and deep contributions to logic for computer science. Logic provides also the theoretical foundation of database systems. Hence, it is almost unavoidable that Gurevich made some great contributions to database theory.

On a theory of probabilistic deductive databases [PDF]
Theory and Practice of Logic Programming, 2001 We propose a framework for modeling uncertainty where both belief and doubt can be given independent, first-class status. We adopt probability theory as the mathematical formalism for manipulating uncertainty. An agent can express the uncertainty in her knowledge about a piece of information in the form of a confidence level, consisting of a pair of ...

A formal model for ledger management systems based on contracts and temporal logic
Blockchain: Research and Applications, 2022 A key component of blockchain technology is the ledger, viz., a database that, unlike standard databases, keeps in memory the complete history of past transactions as in a notarial archive for the benefit of any future test.

Towards a Hybrid Immune Algorithm Based on Danger Theory for Database Security
IEEE Access, 2020 In Databases, the most prevalent cause of data breaches comes from insiders who misuse their account privileges. Due to the difficulty of discovering such breaches, an adaptive, accurate, and proactive database security strategy is required.

Constraint processing in relational database systems: From theory to implementation [PDF]
, 2010 Constraint satisfaction problems (CSP) are frequently solved over data residing in relational database systems. In such scenarios, the database is typically just used as a data storage back end. However, there exist important advantages, such as the wide
