The BaBar Prompt Reconstruction manager: A real life example of a constructive approach to software development Original Research Article

The need for a working system to automate the Online Prompt Reconstruction (OPR) subsystem has led the members of the OPR group to develop their system using the software cycles development model. Starting with a complete design, they have implemented the system in each cycle using multi-paradigm methods, combining different techniques and languages and enhancing the working system gradually while using it in the production phase. The OPR software has evolved from a set of shell scripts, which were run manually, into a set of partially automated Perl/shell scripts. These will be transformed into a completely automated system based on Perl/C++/Java code with a CORBA distributed architecture, able to execute parallel/multiple PR jobs on a farm of Unix machines.
