it is there to fulfill all possible preferences and expectations of
intended audience. Custom software exists to serve companies
ranging from small size through medium size and ultimately by
large organizations for their core and vital functions.
     Large companies commonly use custom software for
critical functions such as content management, inventory
management, customer relationship management and human
resource management [1]. Mostly these applications are
desktop based. Successfully installation of custom software
requires different equipments such as:
     Switches: Use for connecting all clients (4 port switch, 8
port switch, 16 ports switch, 24 ports switch etc).
     Database Server: A System for storage purpose is required
(RAID or Core I3 or Core I7 system, database software,
operating system, ant viruses).
     Backup Devices: External storage devices such as compact
disk, external hard disks, tap devices; logical backup devices
etc are required.
     Compatible framework i.e. (Microsoft .NET Framework
v3.0 or higher) must be installed on the client’s machine.
     A database administrator is required for backup & recovery
and others database issues.
      Successful reinstallation is needed after crash of server.

access the application outside organization.


 VII.     SOLUTION OF DRAWBACK OF CBCS USING
                        TA
CBCS should not be accessed at outside the organization, this
issue must be handled by the organization authority not any
third party member. So it can be done by using password
handler application. Tinny Application (TA) a small
application which will handle the password policy of CBCS.
CBCS will be uploaded on ftp while TA will be installed on
each machine in relevant organization. Every one in an
organization can work on CBCS because TA will be installed
over here while at out side organization CBCS can not be
worked because TA will not be installed at out side the
organization. Following figure is showing that organization’s
clients can work on CBCS by using TA while clients other than
organization can not work on such type of CBCS.
