Situation of Agro-Data-Grid Rice data service Integration system: RiceMet

Situation of Agro-Data-Grid

MetBroker， DemBroker， ChitsuBroker， ResourceServer， SoilBroker Addressing the issue of heterogeneity, both data and sof

tware. data sharing Easy for data integration

However, these are all environment related data We need crop data service for Agro-Data-Grid

Rice data service-an attempt for Crop data service

Digital data sets are continuously produced In spreadsheet format Locally stored, isolated Hard to share among researchers Even harder for data merging and integration

Data service is the basis to address these issues

Merging rice data needs a flexible data model.

Merged data can be shared and integrated via consistent access

Data service provides an access for integration with environmental data

Implementation of Rice data service EJB3: Simpler and more flexible than older

version POJO: reusable components Annotation Dependency injection: simpler JNDI lookup Less configurations

Rice Data service 2 Entity Beans: RiceDataBean, LocationBean

Mapping rice data and location data 1 session bean: RiceDataSessionBean

Business logic to manipulate these data

RiceMet - Ajax+Google Maps

By using google maps, experimental locations are visible on the map

help user to select datasets based on these locations

ZK: Ajax toolkit with Java

Ajax-based Rich User Interfaces. Java based programming, no Javascript Rich components Event-driven Model Server centric processing Full support to Google maps
