• Motivation

• Project details

• Link to GSIM model

• Application

• Outlook and next steps


Motivation

• in the past no central repository for metadata/data different view concerning one and the same variable (e.g.

current activity status) no standardised metadata management (what kind of

metadata, what format, …) difficult data exchange between units (due to lack of

harmonisation, change of the data structure, ..)

• solution – statistical datawarehouse (sDWH) internal, house-wide, easy accessible centralized platform harmonisation and standardisation of metadata/data instance for data dissemination and visualisation


Project details

sDWH project was established in 2014 • big picture – rough plan of the sDWH • focus on metadata management

technical solution was fixed in 2015 • self developed solution with common in-house standard

components (DB2 database + Java Application)

1. trial stage with prototype of the sDWH in summer 2016 • implementation of test-user suggestions

2. trial stage in spring 2017

start of the distribution in April 2017


Link to GSIM model

• data concept within sDWH is based on GSIM model

• currently five information objects are covered by the sDWH

product dimensional data set dimensional data structure represented variable instance variable administrative register (coming soon)

• number of embedded information objects will increase because of further developments

Roles in the sDWH

• sDWH administrators

• sDWH users

• sDWH quality administrators have the task to approve represented variables and

previously defined data sets

• sDWH system administrators have extended competences, responsible for the

implementation regarding further development and programming


Outlook and next steps

• implementation of the metadata of administrative data available at Statistics Austria

• data dissemination and data visualisation based on sDWH

STATcube Export integration of a visualisation tool (evaluating tableau) implementation of automatically map creation (spatial

visualisation)

• mapping of data processing
