Abstract: A system for storing data in a memory comprises a memory operable to store a database, wherein the database comprises an array, and the array comprises a number of elements uniquely identifiable by their location in relation to an origin point of the array, an interface operable to receive first data to be stored in the array; and a processor communicatively coupled to the memory and the interface, the processor operable to convert the first data to a hash using a hash function, determine a selected number of character positions of the hash, and identify an array element according to the character values of the selected character positions of the hash.

Abstract: A system for storing messages in an on-disk database (ODDB), comprises an interface operable to receive a first message comprising first data from an execution venue, wherein the first message is one of a group of associated messages related to a financial transaction, a processor communicatively coupled to the interface, the processor is operable to load the first message into an in-memory database (IMDB), identify a second message in the group of associated messages, transform the second message with the first data from the first message, and determine whether all messages in the associated group of messages have been loaded into the IMDB, and the interface is further operable to transfer the first message to the ODDB.
