@inproceedings{Benedikt2016GeneratingPF, title={Generating Plans from Proofs: The Interpolation-based Approach to Query Reformulation}, author={Michael Benedikt and Julien Leblay and Balder ten Cate and Efthymia Tsamoura}, booktitle={Synthesis Lectures on Data Management}, year={2016} }
Abstract Query reformulation refers to a process of translating a source query—a request for information in some high-level logic-based language—into a target plan that abides by certain interface ...

Equivalent Rewritings on Path Views with Binding Patterns
- Computer ScienceESWC
- 2020
It is shown how queries can be rewritten into equivalent execution plans, which are guaranteed to deliver the same results as the query on all databases, and how this method can be used to answer queries on real-world Web services.
First-Order Ontology Mediated Database Querying via Query Reformulation
- Computer ScienceA Comprehensive Guide Through the Italian Database Research
- 2018
This work considers first-order ontology systems playing the role of a conceptual model of a database represented as a classical finite relational store, either with an open world or a closed world reading.
1 Generating collection transformations from proofs
- Computer Science
This work shows that one can synthesize transformations from proofs that a formula provides an implicit definition, where the proof is in an intuitionistic calculus that captures a natural style of reasoning about nested collections.
Projective Beth Definability and Craig Interpolation for Relational Query Optimization (Material to Accompany Invited Talk)
- Computer ScienceSOQE@KR
- 2021
This talk elaborates on how logic-based approaches can be used to capture both the high-level conceptual views of information and the low-level physical layout of data and presents the design of a relational query optimizer based on Craig interpolation that allows users to compile both queries and updates to low- level code that operates directly over a physical encoding of the data.

This work shows that one can synthesize transformations from proofs that a formula provides an implicit definition, where the proof is in an intuitionistic calculus that captures a natural style of reasoning about nested collections.
Generating collection queries from proofs
- Computer ScienceArXiv
- 2020
This work shows that NRC has a strong connection with first-order logic: it contains exactly the transformations that are implicitly definable by formulas $\varphi$ in first- order logic with quantification suited for nested collections.

Generating low-cost plans from proofs
- Computer SciencePODS
- 2014
This work starts by overviewing a correspondence between proofs and restricted-interface plans in the context of arbitrary first-order constraints, based on interpolation, and provides direct plan-generation algorithms for schemas based on tuple-generating dependencies.
Exact Query Reformulation over Databases with First-order and Description Logics Ontologies
- Computer ScienceJ. Artif. Intell. Res.

A non-trivial application of the framework with ontologies in the very expressive ALCHOIQ description logic is presented, by providing effective means to compute safe-range first-order exact reformulations of queries.
Answering queries using templates with binding patterns (extended abstract)

- 1995
This work shows how to decide with a nondeterministic polynomial-time algorithm whether the given query can be answered and extends the results to allow arithmetic comparisons in the givenquery and in the templates.
Towards a Logical Reconstruction of Relational Database Theory
- Computer ScienceOn Conceptual Modelling
- 1982
Insofar as database theory can be said to owe a debt to logic, the currency on loan is model theoretic in the sense that a database can be viewed as a particular kind of first order interpretation,…
Optimal implementation of conjunctive queries in relational data bases
- Computer ScienceSTOC '77
- 1977
It is shown that while answering conjunctive queries is NP complete (general queries are PSPACE complete), one can find an implementation that is within a constant of optimal.
Answering queries with useful bindings

- 2001
This article proposes a query-planning framework to answer queries in the presence of limited access patterns, and develops algorithms to solve optimization problems in this framework, and thus construct an efficient program to answer a query.
PDQ: Proof-driven Query Answering over Web-based Data

PDQ (Proof-Driven Query Answering), a system for determining a query plan in the presence of web-based sources, is introduced, taking the novel approach of generating query plans from proofs that a query is answerable.
Querying with Access Patterns and Integrity Constraints
- Computer ScienceProc. VLDB Endow.
- 2015
This paper presents a system in which classical cost-based join optimization is extended to support both access-restrictions and constraints, and explores a space of proofs that witness the answering of the query, where each proof has a direct correspondence with a query plan.
