The relational data model and relational algebra
The early days of database engines (1960’s) saw several competing “data models” (the formal specifications for how the system represents and reasons about data). Academic researchers had proposed several models that were rich, expressive, and provided admirable data independence, but that were impossible to implement efficiently. The models used by working systems, on the other hand, tended to ...
متن کاملIs relational aggression part of the externalizing spectrum? a bifactor model of youth antisocial behavior.
The primary purpose of the present study was to examine support for the inclusion of relational aggression (RAgg) alongside physical aggression (Agg) and rule-breaking behaviors (RB) as a subfactor of antisocial behavior (ASB). Caregiver reports were collected for 1,087 youth (48.9% male) ages 6-18. Results indicated that all three subfactors of ASB demonstrated substantial loadings on a genera...
متن کاملConstruct Validity of the Social Provisions Scale: A Bifactor Exploratory Structural Equation Modeling Approach.
Extant theory posits well-differentiated dimensions of perceived social support as measured using the Social Provisions Scale (SPS). However, evidence is inconsistent with this multidimensionality perspective, with SPS factor correlations near unity and higher between-factor than within-factor item correlations. This article reports on research investigating the internal structure, gender invar...
متن کاملThe Local Relational Model: Model and Proof Theory
In this paper we identify desirable data management mechanisms for peer-to-peer (P2P) computing. P2P networks have to remain open and dynamic, while peers remain autonomous and need only be aware of their immediate acquaintances. In such a setting, we argue that one cannot assume the existence of a global schema for all the peer databases. Instead, one needs a data model which views the space o...
متن کاملUsing Relevance Feedback within the Relational Model for TREC-5
For TREC-5, we enhanced our existing prototype that implements relevance ranking using the AT&T DBC-1012 Model 4 parallel database machine to include relevance feedback. We identified SQL to compute relevance feedback and ran several experiments to identify good cutoffs for the number of documents that should be assumed to be relevant and the number of terms to add to a query. We also tried to ...
