Sizing and Performance
•Max No of Clients handled by Loan offOfficer (8 Hrs per day * 60) minutes /10 = 48 ~ 50 clients •Total number of clients served in a day
50 Clients per loan officer * 400 Loan Officers = 20000 Clients •Estimated number of transactions per customer will be limited to 3. (Assuming a client registration, a loan disbursement/loan collection and a saving account.)
Transaction per day = 20000 clients * 3 transactions = 60000 transactions •Estimated number of transactions on average to the BOSS server: 2 per sec
Avg Transactions/sec = 60000/(8 Hrs *60 * 60 ) = ~2 Transactions per second. •Estimated maximum data upload size: 3 MB per day
Client record size = Average no of data fields per request = 3030 data fields per request * 100 bytes per field = 3000 bytes /1024 ~ 3KBTotal size = 60000 * 3KB = 18000KB ~ 18MB
•Response time for client request and timeout: 1 second response and 5 second timeout •BOSS database must be able to store data up to one week Data must be processed within a week. •Database size for 7 days client records storage:
Total size = 7* 18 = 126 MB

The mobile channel application for the Micro Finance system is built into IPT300 Handheld device.
Application development on the device will use .NET Compact Framework 3.5 with the aid of SDK for IPT300 handheld.
To store data locally SQLCE 3.5 DB shall be used on IPT-300 Industrial Handheld Terminal
MVC Architecture on .NET compact Edition shall be used; which helps inA structured way of passing data Better organized codePlatform independent navigation to views
More details along with analysis and package diagram are described in the Transition strategy for Mobile Application document

BOSS is installed as a web Model View Control (MVC) on Apache tomcat
BOSS shall be written as a java based web application (J2EE)
implementation approach for BOSS is to use Spring MVC
BOSS has its own data storage and for that we are using MySQL
DispatcherServlet is one of the boundary objects of BOSS
RequestDispatcher is the control object
ModelAndView contains the model data and the name of the view
