DETAILED USER & TECHNICAL REQUIREMENTS FOR CDPS
AND USE-CASE MODELS
Ref: PHASE V
Number
TA-0040
TA-0050
TA-0060
Description
order to ensure integrity of data and consistency in application of business rules.
This should greatly simplify the maintenance of the system as well as increase
MCA’s ability to respond effectively and in a timely manner to user initiated
change requests in response to changes in customs law, policies and practices.
Physical independence. CDPS must address the need for increasing the reach
and range of the application system irrespective of where the system is
physically located so as to permit two way access to/from external financial
institutions, governmental institutions and citizens, irrespective of their physical
location.
Modularity and flexibility in making enhancement. CDPS must address the
requirement for a components-based modular system design so as to provide the
MCA the capability to enhance the system to keep up with changing rules and
procedures.
Data consolidation and processing. CDPS must ensure that all data is stored in
a database ensuring that there is no redundant data (i.e. normalized database
schema) in order to simplify data access and provide a consolidated logical view
of data, regardless of the organization and location of the financial information.
As a result, data processing will be more accurate, consistent and timely,
avoiding redundancy and increasing processing efficiency.

5.2.9 Operating Environment
CDPS will operate within the following environment in MCA.
Number Description
OE-0000 Estimated Transaction Volumes: There will be approximately 2000 MCA
users of CDPS. There will be around 1000 MCA users concurrently accessing
CDPS. It is anticipated that over the next few years the number of users could
increase. CDPS usage patterns vary based upon the hour in the day and the
month of the year (see Figure 1 and Figure 2). The following information
provides some very broad volumetric for peak and average processing days:
• Daily CDPS transactions peak at around 2pm to 4pm. During the peak
hour the number of transactions reaches on average 190 SAD transactions
per hour and 184 transit transactions per hour.
• The average amount of daily transactions is: 1178 SAD transactions per
day and 1420 transit transactions per day.
Note: The above estimates for the transaction volumes are based upon the
historical data available for the period January-July 2008.
OE-0010 Communication Links to BCOs: MCA will use a VPN system to connect the
BCOs to CDPS Servers running at Headquarters. All BCOs shall be connected
with the MCA Headquarters by two Internet links provided by two independent
Internet providers. The speed of these lines will vary, but the slowest lines shall
be at least 256 Kbps.
OE-0020 Server Hardware Platform: Currently, MCA does not have servers which can
be used to run CDPS. CDPS server(s) has to be sized by MCA and CDPS
vendor to meet the performance requirements of CDPS. The vendor must
specify the technical requirements for the recommended hardware for the servers
and other resources:
• Processors, hard disks, backup devices per server.
