  1. SIS Database structure and architecture NCEAS working group S.Barbara, 18 July 2001

  2. Contents • The challenge • The concept • Status

  3. The challenge • SIS must accommodate data on a huge variety of organisms • Data requirements are not yet fully defined • New data sets may need to be managed • New data sets may be needed for future products • Incomplete predefined output (e.g. products to be defined)

  4. The challenge • Define a minimum common denominator for all the information requirements of SSC • Create a modular data structure to accommodate future needs

  5. The concept • Species are central to all SSC information • Taxonomy is the main “authority list” of SIS • SIS is centred around a minimum set of “information objects” common to all taxa • More information can be added by adding new “information objects”

  6. The concept • Authority lists are: • Lists of keywords on a specific topic • A way to standardise information • A way to enable control of the information added to the database

  7. The concept • Information objects are: • Self-contained pieces of information, e.g.: • The species habitat description • The species geographic range • … • The way SIS implements modularity in the data structure

  8. The concept • SIS minimum set of information objects: • Red Listing Data • Population data • Geographic range • Habitat requirements • Conservation actions • References

  9. The concept Primary key to access information Objects containing different types of information Red Listing Data Population data Geographic range Habitat requirements Conservation actions References … SG modules Taxonomy Links

  10. Status • Data structure implemented in Access • All of the core information objects have their structure in SIS • Plans to migrate the structure under Oracle to enhance future compatibility

  11. Web enablingOverview • The Web Enabled SIS builds on the existing data structure of the stand alone SIS software package • It will enhance the existing functionalities of SIS to support concurrent access, data currency and broader accessibility

  12. Web enabling Overview

  13. Web enablingOverview • The Web Enabled SIS functionalities will be assembled to support to following main sets of applications • Specialist Tools • SG Administration • Biodiversity Analysis • Reader • CSU Administration

  14. Web enablingOverview • The Web Enabled SIS users will be grouped in the following categories • Specialist User • SG Data Authority • SG External Reviewer • Web User • SSC-CSU Internal User • SSC-CSU Administrator
