networks to use the maximum resources and performance of the infrastructural components, to
enhance efficiency and dramatically reduce IT expenses. It also allows simple expansion of
additional resources. In addition, the virtualization concept is providing load balancing, security
isolation and advanced resource controls to manage the system performances.
3. Data Storage Strategy
Dividing the operational data storage (ODS), where data from multiple sources are stored and
historical data will dramatically increase the performance of the SW system.
One of the widely recommended approaches is to divide the data on a separate physical and
logical repository. When used (written off and expired) permit and certificates are considered
closed, with extract, transform, load (ETL) process the data should be pulled out from the source
repository and placing it into a data warehouse. Data warehouse will also support reporting and
analysis services of the SW.
5.2.3 Data and Business Harmonisation
Three challenges occur or relate to the data and business harmonization. The table below
shows these challenges and possible strategies and options to overcome these challenges:
Table 27: Data and Business Harmonisation - Challenges and Options
Challenges
1. Lack of Systematic Approach for Business Process and Data Mapping
The lack of use of a systematic approach to design the business processes is one of the biggest
challenges for the design and development of the SW. Many OIC Member States SWs are not or
only partially using the business process methodology to collect, map and define the workflow. In
addition, there is a no proper business processes catalogue to document, and define
dependencies and data associated with the workflow.
Why does it matter?
Lack of coherent data and process mapping and syntax on reference data lead to processing
errors, especially in the statistics, analysis and reporting services.
2. Lack of Integration into End-to-end Business Processes of Agencies
At present, one of the main problems facing SWs is that there is no harmonized IT strategy across
the government. Many government agencies therefore don’t have a vision and operate isolated IT
systems, partially covering their business processes.
The result is that data and knowledge information exists in isolation from each other and IT
systems do not communicate with each other.
Why is it important?
In such an isolated environment there is no easy way to exchange data between systems, o
implement higher-level intelligence, and to enhance and upgrade these systems to support the
