SIS Database structure and architecture

NCEAS working group

• The challenge

• The concept

• Status

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)

The challenge

• Define a minimum common denominator for all the information requirements of SSC

• Create a modular data structure to accommodate future needs

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”

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

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

The concept

• SIS minimum set of information objects:– Red Listing Data

• Population data

• Geographic range

– Habitat requirements

– Conservation actions

– References

Taxonomy

Primary key to access information

Objects containing different types of information

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

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

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

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
