    摘要: This invention provides a method and apparatus for loading data having a predetermined order of data records from a source into a database using parallel processing. Using one or more reading agents, data records are read from the source in which they are stored. These data records are stored in groups of records. Each group of stored records are tagged with a sequence identifier corresponding to the predetermined order of data. Apparatus is provided for formatting the data records in the groups using a plurality of formatting agents in parallel. The formatted records are stored in formatted record groups. Sequence identifiers are written for each of the groups to the respective formatted record group. A record identification apparatus is provided for assigning page locations for the records using the sequence identifiers to maintain the predetermined order.
