Data services

Abstract

Data services key insightsData services differ from traditional Web services in that they serve as "fronts" for data and are based on a richer model of that data.The growing importance of data services in the movement toward a hosted-services world is evidenced by the number of contexts within which they have been utilized in recent years: data publishing, data exchange and integration, service-oriented architectures (soA), data as a service (Daas), and most recently, cloud computing.While data services were initially conceived to solve problems in the enterprise world, the cloud is now making data services accessible to a much broader range of consumers.

A decentralized and service-based approach to proactively correlating stream data

“…Data service is a specialization of Web service which can be deployed on top of data stores, other services, or applications (Carey, 2012). However, because of the " request-response"model for traditional data service, it suffers certain limitations in an IoT environment, such as to collect, process, deliver and correlate continuous sensor data.…”

A Novel Architectural Framework for Aggregated Subscriber Profile

“…Framework proposed by (Michele et al, 2008) provides flexibility to adopt such external information and helps CSPs to expose meaningful and dynamic Subscriber profile information to the Application Plane. Proposed Framework is based on Service Oriented Architecture and Data Services Principle and Techniques demonstrated by (Subramanyam and Walker, 2009), discussed by (Carey et al, 2012;Manu, 2005).…”

“…Defined a typical Data Model for proof of concept implementation purpose and considered couple of data sources using Relational Data Base tables. Implemented physical and logical Data services definitions using Data Services Engine as demonstrated by (Subramanyam and Walker, 2009), discussed by (Carey et al, 2012;Manu, 2005). Aggregated Profile definition considered with elements as stated below:…”

Towards DaaS 2.0: Enriching Data Models

“…Third parties can add data into the original infrastructure through a data service [2], or, in some cases, add very limited functionality such as custom overlays in Google maps.…”
