Abstract: A system for executing a plurality of transactions comprises a first processor and a memory. The first processor is configured to execute a first transaction comprising: providing a plurality of indications to make a plurality of first changes to a plurality of first records of a database; and committing the first transaction by updating the status of the first transaction in a transaction table while not providing an indication to update the status of the first records from pending. The memory is coupled to the first processor and configured to store the transaction table.

Abstract: A system for analysis and transaction processing includes an interface and a processor. The interface is configured to receive a task. The processor is configured to determine a processing estimate associated with the task by determining required resources for a set of possible processing solutions to perform the task and to determine a task engine based at least in part on the processing estimate. The task engine comprises an analysis engine or a transaction engine. The analysis engine or the transaction engine is used to process the task. The processor is further to provide the task to the task engine.
