 ## Description
 
-This digital record contains historical air pollution and air quality data from approximately 20 air monitoring stations
-in Vienna, spanning the years from 1980 to 2021. The data was provided by the Umweltbundesamt and is stored in its
-original form in this record. This record forms the basis of an analysis carried out in a bachelor's thesis at the TU 
-Wien.
+As part of a literature study, the research unit of data science has collected data on 47 Trusted Research Environments
+(TREs) who enable analysis of confidential data under strict security assertions who protect the data with technical, 
+organizational and legal measures from (accidentally) being leaked outside the facility. The literature study shows that
+47 TREs worldwide provide access to confidential data of which two-thirds provide data themselves (n=32, 68%), 
+predominantly via secure remote access (n=46, 98%).
 
 ## Solution
 
+We designed a database schema that allows collection of the data with correct primary key and foreign-key relationships.
+Three defined views allow for a simpler exploration of the study data. The analysis of the data was performed in TU
+Wien's virtual research environment using [JupyterHub](https://science.datalab.tuwien.ac.at/) as well as the chart
