re: http://www.garlic.com/~lynn/2009q.html#67 Now is time for banks to replace core system according to Accenture semi-advertisement warning ... in the past couple yrs, i've done some work with a company that does business rule specification ... which then generates relatively fine-grain, parallel friendly SQL. The magic is being able to translate the business rule specifications into small enough units of work (characterized by parallel-friendly SQL statements) and then rely on modern generation of RDBMS implementations to achieve the parallelization. They've done some end-to-end bank business process implementations that have significantly more reporting and audit control than typical operation ... with a lot being a side-effect of it being done at the business rule specification level ... and some of it being real-time "straight-through processing" ... resulting in real-time status/reports at all points in time. They've been able to demonstrate extremely high DBMS transaction rates (in part because of making the operations finer grain) ... but also very high financial transaction rates & thruput (a lot of RDBMS implementations are starting to demonstrate parallelization efficiencies ... better than the parallelization programming tools that were in use in the 90s). the business rule level specification makes for rapid development and extremely agile change cycles. fine-grain SQL units of work are generated from the business rule specifications ... and relies on parallel RDBMS to achieve high throuhput. slightly related thread on some "modern" high-performance parallel RDBMS work http://www.garlic.com/~lynn/2009p.html#43 From The Annals of Release No Software Before Its Time http://www.garlic.com/~lynn/2009p.html#46 From The Annals of Release No Software Before Its Time -- 40+yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
