A multi-set extended relational algebra: a formal approach to a practical issue [PDF]
, 1993 The relational data model is based on sets of tuples, i.e. it does not allow duplicate tuples an a relation. Many database languages and systems do require multi-set semantics though, either because of functional requirements or because of the high costs

Towards the absolute planes: a new calibration of the Bolometric Corrections and Temperature scales for Population II Giants [PDF]
, 1998 We present new determinations of bolometric corrections and effective temperature scales as a function of infrared and optical colors, using a large database of photometric observations of about 6500 Population II giants in Galactic Globular Clusters ...

Prognosing Human Activity Using Actions Forecast and Structured Database
IEEE Access, 2020 The goal of this work is to forecast human activities that may require robot assistance. Each activity consists of consecutive actions. Each action is bounded by initial and final state and is created by the motion trajectory.

Database Slicing on Relational Databases
Acta Cybernetica, 2014 Many software systems today use databases to permanently store their data. Testing, bug finding and migration are complex problems in the case of databases that contain many records. Here, our method can speed up these processes if we can select a smaller piece of the database (called a slice) that contains all of the records belonging to the slicing ...

Comparison of NoSQL Database and Traditional Database-An emphatic analysis
JOIV: International Journal on Informatics Visualization, 2018 A Huge amount of data is manipulated by using the web application, Facebook, Twitter, social sites etc. Most of the data are unstructured data. It is not desirable for storing, performing and analyzing data in the relational database for huge data.

End-to-End Database Software Security
Software, 2023 End-to-end security is essential for relational database software. Most database management software provide data protection at the server side and in transit, but data are no longer protected once they arrive at the client software.

Nest and Unnest Operators in Nested Relations
Data Science Journal, 2008 By distinguishing nested attributes as Decomposable and Non-Decomposable, it is proved that for all nested relations, unnesting and then renesting on the same attribute yields the original relation subject only to the elimination of duplicate data ...
