Non-indexed in-memory data storage and retrieval

摘要

Systems, methods and user interfaces that allow rapid storage and retrieval of trading data are provided. Trading data records are arranged as a non-indexed collection of data records. The physical location of trading data records stored in a computer-readable medium corresponds to the order that queries are performed. Queries may be performed by analyzing attributes of all of the trading data records, without speed limitations associated with indexed databases.

主权项

1. A computer-implemented method of processing trading data stored on a computer-readable medium comprising:
(a) receiving a first trading record comprising trading data; (b) storing at least a portion of the trading data from the first trading record on a computer-readable medium; (c) receiving a second trading record comprising trading data; (d) storing sequentially at least a portion of the trading data from the second trading record on the computer-readable medium in a reception order of the first and second trading records, wherein the trading data from the second trading record is stored substantially physically adjacent to the trading data received from the first trading record and wherein neither the trading data from the first trading record nor the trading data from the second trading record is associated with an index; (e) receiving a search query; and (f) sequentially comparing, by a computer, at least a portion of the search query with the non-indexed collection of substantially sequential trading data located on the computer-readable medium beginning at a commencing location on the computer readable medium and continuing in a substantially physically adjacent sequential manner through all of the trading data stored on the computer readable medium to retrieve information from the trading records responsive to the search query.
