Relational to RDF Data Migration by Query Co-Evaluation
In this paper we define a new algorithm to convert an input relational database to an output set of RDF triples. The algorithm can be used to e.g. load CSV data into a financial OWL ontology such as FIBO.
Using CQL to compose a data warehouse with reduced costs and risks
CQL Demo One way to answer business questions is to gather relevant data, integrate it according to business rules, and then populate a data warehouse in your favorite data store with the integrated information. If the warehouse is properly designed, and the...
Fast Left-Kan Extensions Using The Chase
In this paper we show how to compute left-Kan extensions of set-valued functors with the venerable chase algorithm from relational data base theory.
Informal Data Transformation Considered Harmful
We take a popular position that AI systems are limited more by the integrity of the data they are learning from than by the sophistication of their algorithms.
Financial Reporting Data Warehousing with CQL
Using a simplified financial reporting example, we examine how traditional data warehouses are put together. We then propose an improved method for creating data warehouses: using the categorical query language CQL.
Compositional Models for Power Systems
We consider the issue of multiple overlapping data models in the context of modern power grids.
Algebraic Property Graphs
In this paper we consider how to integrate a simple and developer-friendly data model such as the property graph with more complex and less user-friendly data models such as relational database tables.
Categorical Data Integration for Computational Science
CQL is an open-source query and data integration scripting language that can be applied to common challenges in the field of computational science.
Algebraic Model Management: A Survey
We describe a new model management approach based on algebraic specification following a survey of the field of model management.
Algebraic Data Integration
Our approach to data integration is based on combining techniques from functional programming, category theory and database theory.
