Backend Implementation I
The backend software can be parallel or sequential and simulation or information based
- It can be COBOL, Fortran, C++, Perl ...
We need to define in XML its interface needed to
- run it
- set its parameters -- i.e. its input mechanisms
- get its output -- numbers or visualization
This backend program interface is defined as an XML file e.g. <program name=“physicssimulation1”> <run domain=“npac” machine=“maryland” type=“pc” os=“nt” >c:\myprogs\a.out</run> <input type=“htmlform” > <name>userinput</name> <field default=“10” >iterations</field> ………. </input> <output> …</output> </program>
Becomes HTML form with name
userinput and text field iterations
with default value 10 on client
