TODAY’S CONTENTS
• XBRL has become a key element for Regtech. However, the lack of suitable technology has prevented regulators from effective use of XBRL data.
• In this session, we will introduce the latest challenges to develop a revolutionary breakthrough to realize ultimate use of XBRL potential and then observe the cost reduction process within regulators’ business flow.
• Some future view of AI application for regulatory purpose will be also introduced and enhance the audiences’ imagination towards the future Regtech.

Regulatory Data Format
Monitoring Period Nature of Data Popular Data Format
Real Time Simple, high speed,
i.e. event-logCSV, TEXT
Daily Slightly complicated,i.e. Transaction messaging
CSV, TEXT, XML
Periodical Complicated, low speed,
i.e. reportingXML, XBRL
On-demand Flexible structure,
i.e. reporting
HTML, PDF, XML, XBRL,Excel

Hypercubes (1)
Current technologies cannot cope with the flexibility
Relational Databases / OLAP
•High rigidity
•Low dimensionality
•No flexibility
Different schema for every taxonomy version

Hypercubes (3)
Current NoSQL technologies cannot cope with the analytical requirements
•Unlimited flexibility
•Unlimited characteristics
•No data semblance
NoSQL / Hadoop
Data without rules is not interpretable
No instant analytics = No flexibility + high TCO

Hypercubes (4)
Sweet spot between the extremes
Flexibility + semblance of dataTaxonomy = schema (low maintenance)User decides which schema to use

Hypercubes (5)
How it works: Hypercube querying
Schema:
Hypercubes / Tables
Facts
Schema stored separately
No data migration cost
Gives full control to the end-user

The most important feature is all these functions are
free from maintenance burden, even when new
taxonomy based data is coming!
