The vision of declarative-data driven coordination (D3C) [3] enables users to communicate and coordinate through declarative specifications. A declarative query mechanism for D3C, named entangled queries, has been presented in [2]. Raising this notion to the level of transactions introduces many new challenges, such as a formal characterization of additional anomalies [6] or a choice of a concu...

Foundations of Declarative Data Analysis Using Limit Datalog Programs

Motivated by applications in declarative data analysis, we study DatalogZ—an extension of positive Datalog with arithmetic functions over integers. This language is known to be undecidable, so we propose two fragments. In limit DatalogZ predicates are axiomatised to keep minimal/maximal numeric values, allowing us to show that fact entailment is CONEXPTIME-complete in combined, and CONP-complet...

Breaking the Chains: On Declarative Data Analysis and Data Independence in the Big Data Era

Data management research, systems, and technologies have drastically improved the availability of data analysis capabilities, particularly for non-experts, due in part to low-entry barriers and reduced ownership costs (e.g., for data management infrastructures and applications). Major reasons for the widespread success of database systems and today’s multi-billion dollar data management market ...
