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

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 enabling Overview 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. 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 enabling Overview 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

15. Web enabling Software architecture WESIS Specialist Toolset Oracle 9i RDBMS Oracle 9iAS Local Business Logic (Local A.S. OC4J) Local RDBMS (Oracle 9i Lite) Java Application (Swing U.I.)
