When creating a relational model, there are a few things you should be mindful of. First, you have to ensure that the data is represented in the form of a set of relations. Also, every one of the relations must be indicated on the table while also making sure that each of the rows ...
Tuples are an integral part of therelational data model, which was first proposed by Edgar F. Codd in the 1970s. The model describes how to represent data in a way that ensures the data'sintegrityat all times, regardless of the supported workloads and applications. Since its introduction, ...

Asymmetric redundancy of tuples provides a more comprehensive method compared to the other approaches, especially, when the fuzzy relational data model is used to represent either decision table or more accurate information.Rolly IntanMasao Mukaidono...
We introduce Spatial Tuples, an extension of the basic tuple-based model for distributed multi-agent system coordination where (a) tuples are conceptually placed in regions of the physical world and possibly move anchored to a mobile computational device, (b) the behaviour of standard Linda coord...
Tuple is a basic concept in relational database. Relationship is a table. Each row in the table (each record in the database) is a tuple and each column is an attribute. In a two-dimensional table, tuples are also called rows.Why use it...

This section will introduce concepts and methods to be referred to this paper, including the multi-granularity LTS model and the grey relational analysis model. The framework of knowledge aggregation in the EDM EDM can be regarded as a problem-solving activity terminated by a solution, thus it ...
As an example, we providetuple calculussemantics for the query given in Figure 3. Here the Cartesian product and projection operators have been expressed intuple calculus.
