A Meta-Analysis Comparing Relational and Semantic Models
نویسندگان
چکیده
Data modeling is the sine quo non of systems development and one of the most widely researched topics in the database literature. In the past three decades, semantic data modeling has emerged as an alternative to traditional relational modeling. The majority of the research in data modeling suggests that the use of semantic data models leads to better performance; however, the findings are not conclusive and are sometimes inconsistent. The discrepancies that exist in the data modeling literature and the relatively low statistical power in the studies make meta-analysis a viable choice in analyzing and integrating the findings of these studies.

Meta-Textual Models of Relational Knowledgebase
The formalising of relations of the theory of relational databases encompasses in the main conventional entity set models and data structures. There is an analytical vehicle and formal definition of knowledge bases. The offered tool of meta-textual relational models of knowledge opens broad capabilities of development of the theory of relational knowledge bases. The basic fields of application:...
متن کاملDatabase Interfaces: A Conceptual Framework and a Meta-Analysis on Natural Language Studies
Data utilization has been cited as one of the top MIS issues in many surveys (Brancheau and Wetherbe, 1987; McCormick, 1991; Niederman et al., 1991; Grover and Goslar, 1993). In the late 1970’s and early 1980’s, database research focused on relational, network and hierarchical models. In particular, experimental studies on user performance largely compared relational model (and languages) with ...
متن کاملDetermination of Financial Failure Indicators by Gray Relational Analysis and Application of Data Envelopment Analysis and Logistic Regression Analysis in BIST 100 Index
Financial failure prediction models have been developed by using Logistic Regression (LR) analysis from traditional statistical methods and Data Envelopment Analysis (DEA), which is a mathematically based nonparametric method over the financial reports of the companies traded in The Istanbul Stock Exchange National 100 Index (BIST 100) between the years 2014-2016. In the development of these mo...
متن کاملTransforming Data Models with UML
This chapter studies an approach to establish a formal connection between data models, in particular between conceptual data models and implementation data models. We use metamodeling techniques based on the Meta Object Facility MOF. MOF may be regarded as a subset of the Unified Modeling Language UML. As prominent example data models, we formally describe and thereby analyze the EntityRelation...
متن کاملRevenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model
The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...
