Data set
(2016. Reference: WCO Data Model)

4.  Multiple documentation submission & data duplication
 Mostly paper-based processing & operations (both front-
end public services & internal workflow of the agency) -
even though some documents available electronically.
 The current paper-based operations make it difficult to
validate the information within the paper documents
(data validation), especially when handling paper
documents from several Participating Government
Agencies (PGAs).
 Difficult, costly and time consuming work coordination
among several regulatory agencies and business
stakeholders during trade facilitation/supply chain
operations.
 Varying ICT-readiness among Stakeholders
Challenges

5.  Single submission
 Business process re-engineering and process
simplification
 Internal workflow automation for PGAs and Automatic
electronic information exchange among PGAs
 Improved ICT Infrastructure.
 Capacity Building
Opportunities

6.  A Data Model is an abstract model that organizes
elements of data and standardizes how they relate to
one another and to properties of the real world.
 Ensures compatibility of data and
ease of sharing data across systems
hereby reducing cost of systems
 Can be used as a blueprint for
the construction of new
software or for re-engineering
a legacy application
THE ROLE OF DATA MODELS (WCO DM V3.x)

7.  Assist in the definition of business rules.
 Assist to define primary source /ownership and usage
(business processes) of each data element.
 Assist to enforce control, confidentiality and integrity.
 Reduce replication of data, data structure, and
functionality, together with the attendant costs of
that duplication in development and maintenance.

10. The role of a Service Oriented Architecture
A service-oriented architecture (SOA) is an architectural pattern in computer
software design in which application components provide services to other
components via a communications protocol, typically over a network. The
principles of service-orientation are independent of any vendor, product or
technology.
The adoption of this approach in Single Window environments will ensure reusable
services; interoperability of systems and client ownership of environment.
