This document describes the first prototype of the Data Aggregation component. This component is the outcome of Task 4.2 of CrowdHEALTH project. The first prototype of the Data Aggregation component is composed of two sub-components (a) Data Aggregation, and (b) Data Importer. The Data Aggregation sub-component is responsible for receiving the data from other components in the CrowdHEALTH platform, whereas the Data Importer component is responsible for importing the data within the big data platform.
This document provides an overview of the implemented functionality and vital information about the interfaces of Data Aggregation with other components. The document also describes how to access the source code and exploit the prototype. Finally, it highlights the baseline technologies underpinning the prototype.
The first prototype of the Data Aggregation component completes the flow of health data from its source to the big-data store within CrowdHEALTH platform, from where it will be used for analytics and decision support. Two more iterations of the delivered prototype are planned in the lifetime of the CrowdHEALTH project. The future prototypes will refine and enhance existing functionality with the view to provide a scalable and reliable aggregation solution for health data from heterogeneous sources.
