To be credible to myself and to others, I developed the methodology of Relationalism and was able to gradually build a new structure, a structure that is composed of three levels —namely, economic theory, policy, and practice; a structure that, for its extraordinary degree of internal and e...
relational algebrasoftware architectureThis paper reports on our experience with a relational approach to support the analysis of existing software architectures. The analysis options provide for visualization and view calculation. The approach has been applied for reverse engineering. It is also possible ...
We present a relational algebra based framework for compiling efficient sparse matrix code from dense DO-ANY loops and a specification of the representation of the sparse matrix. We present experimental data that demonstrates that the code generated by our compiler achieves performance competitive with ...
. . Fm. 2.2 Implementing Parallel Relational Algebra In our discussion of both TC computation and Datalog generally, we have elided important optimizations and implementation details in favor of formality regard- ing the main ideas of both. In practice, it is inefficient to perform multiple ...
understand what’s going on inside the user-defined function and also be able to efficiently execute those. So, the key idea, to summarize, is that we show how you can systematically and automatically translate imperative programs into a declarative form, which is relational alge...
Mathematics Pedagogical Change: Rethinking Identity and Reflective Practice. the article is both a study of one teacher's reflections on a sequence of algebra lessons at the secondary school level, and an exploration into a ran... M Walshaw - 《Journal of Mathematics Teacher Education》 被引量...
Unlike NoSQL logical data models, there exists a standard relational data model which is formally defined through relational algebra and calculus. Being “schema-on-write” is another significant feature that differentiates relational databases from NoSQL stores: schemas must be declared prior to store...

Abstract In this Chapter, we consider relational databases as a data source for the generation of Linked Data, given that they constitute one of the most popular data storage media, containing huge data volumes that feed the vast majority of information systems worldwide. In this context, we re...
