  1. Voyager System Overview Geospatial Pipeline Connectors Browsers Index REST, RSS, XML, JSON, OpenSearch, CSW Web Framework Connector Framework • Analysis • Text Search • Faceting • Caching • Query parsing • Clustering • Synonyms • Suggestions • Authentication • Authorization Office Web Services Desktop GIS / Apps Database • Normalize • Geo-Tag • Gazetteer • Transform • Custom Biz Logic • Open Sextant • etc… Data Delivery (ETL) Doc Mgt Sys Analytics (run models) Custom CDR Broker Open Search CDR Brokered Search Custom Apps Integrated security – LDAP, Windows Authentication, GeoAxis, Voyager internal Data Discovery Index Application

  2. Voyager Components • Discover content across file shares, web severs, portals and other content management systems • Index provides fast relevant search across content • Applications deliver information needed to facilitate decisions Index Discovery Application

  3. Deployment – Single User Single User License • All components installed on the same machine accessed using Voyager Desktop Index Discovery Voyager Desktop

  4. Deployment – Multiple User Index Discovery Web Framework Browsers Voyager Desktop User Access License • All components installed on the same machine • Users can access from any machine using Voyager Desktop or web browser

  5. Deployment – Distributed Discovery Discovery Node Index Web Framework Browsers Discovery Node Voyager Desktop Discovery Node • Let many machines handle indexing processes • Leverage many machines when indexing data • Useful when indexing lots of data, place indexing nodes closest to data

  6. Deployment – Index Replication Index Load Balancer Discovery Web Framework Master Index Browsers Index Voyager Desktop Index • Index replication for high availability and better performance • Highly available – continue serving requests through hardware failures or configuration changes • IncreasedPerformance – Share processing load across many machines. Support more queries with faster results

  7. Deployment – Application Cluster Web Framework Index Discovery Load Balancer Browsers Web Framework Voyager Desktop Web Framework • Multiple Application Servers for high availability and better performance • Highly available – continue serving requests through hardware failures or configuration changes • Increased Performance – Share processing load across many machines. Support more concurrent users doing more things

  8. Users • Central Index • Satellite Index Deployment – Federated Search Query Results Voyager Federated Search Voyager Voyager Voyager Data Data Data • Allow uses to query multiple instances with a single search

  9. Federated Search - Replication Browsers Discovery Master Index (local) Web Framework Voyager Desktop copy copy Voyager Instance Voyager Instance • Replication – Copy remote index locally • Pro: Fast • Con: extra space, coordination

  10. Federated Search – Remote Access Browsers Discovery Master Index (local) Web Framework Voyager Desktop Voyager Instance Voyager Instance • Remote Access – Send requests to remote index • Pro: Simple • Con: potentially slow (depending on network)

  11. Personal Use Voyager Licensing Site License Organizational Use • Individual Productivity • Small organizations • Off-line field use • Teams of people • Large scale data management / SDI • Portals
