ER+: A Conceptual Model for Distributed Multilayer Systems
نویسندگان
چکیده
Distributed databases and data transformation mechanisms are highly relevant to Business Intelligence Data Analytics. Most enterprise systems today have multiple distributed databases, the growing dissemination of Edge-Oriented architectures is driving this trend across many industries business domains. The Entity-Relationship (ER) model fundamental modeling complex systems, but it has shortcomings. In particular, ER cannot represent transport between different locations (or databases) a system, nor can conceptually express operations, such as aggregate line functions, that standard in analytics. Therefore, we propose ER+, an extension model, where distribution, transport, transformation, information generation for operational analytical be visually identified. new ER+ representation another important benefit, provides basis transforming conceptual models into physical implementations data-oriented systems. This work introduces concepts illustrates their application. TPC-H use case also used demonstrate practicality model.

a Simplified Model of Distributed Parameter Systems
A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
متن کاملBuilding a Comprehensive Conceptual Framework for Power Systems Resilience Metrics
Recently, the frequency and severity of natural and man-made disasters (extreme events), which have a high-impact low-frequency (HILF) property, are increased. These disasters can lead to extensive outages, damages, and costs in electric power systems. A power system must be built with “resilience” against disasters, which means its ability to withstand disasters efficiently while ensuring the ...
متن کاملNonlinear effects in a conceptual multilayer cloud model
As conceptual model for a cloud a system is considered which is open for condensate mass transport and subject to internal processes such as cloud microphysical transformation and vertical condensate transport. The effects of microphysical processes are represented in parameterized form and the system is divided into two layers to account for the vertical structure. The evolution is mathematica...
متن کاملHybrid Regenerating Codes for Distributed Storage Systems
Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...
