Oracle is quite comfortable in processing multiple updates or inserst to the same table (the output of any accounting engine is typically inserted CRs/DRs anyway so updated ar not an issue). As far as subsequent building of the sub-ledger balance is concerned, it is quite possibel to segregate these to reduce block contention in the underlying technical environment which is being used. Aptitude is a very powerful engine of this type and very good for analyst formaulation and understanding of business/accounting rules - technically we have proven that it can be as fast as Java code and it does not, in itself, required a relational database, only if you want to read and/or write data to one as source/target of your rules, but it is quite possible to run it in an all-memory environment (I'm currently working with it in an Oracle Coherence/Java distributed memory architecture). It's worth noting that Microgen, whilst they sell Aptitude as a standalone product, have also encapsulated it within a higher-functionality product called MAH (Microgen Accounting Hub) which is being increasingly adopted across a wide investment and retail bank client base as well as in other sectors such as telecoms and digital media. It provides an accounting engine, sub-ledger and data warehouse (latter on Oracle or Teradata). I don't work for Microgen nor am I affiliated with them (any more) and have worked with theit products for a number of years.

It is no longer row based processing unless you want it to be. We have data in Oracle Coherence and connect to that data through a Java API in Aptitude. Its very scalable and we only see Network IO. We have some issues around manageablity but we are working those through. It is a very memory hungry/inefficient thing however. PS - Microgen appear to be optimising Aptitude for use with Terra Data. We are pushing for a Oracle Exadata version. I am pleased to update that Microgen Aptitude doesnt need a Database and it doesnt need an App Server, these are implementation choices.
