Methods and Devices for Processing Sequential Information in Large-Scale Database

摘要

A computer system access in a database a first linear sequence table including a plurality of entries. A respective entry of the plurality of entries includes sequential state information for a respective user. The sequential state information for the respective entry identifies a respective preceding event associated with a respective preceding time and a respective subsequent event associated with a respective subsequent time that is subsequent to the respective preceding time. The computer system initiates aggregation of data in the first linear sequence table to obtain a quantity that corresponds to a number of entries that are associated with a particular preceding event and a particular subsequent event of preceding events and subsequent events of the plurality of entries.

at a computer system with one or more processors and memory:
accessing in a database a first linear sequence table including a plurality of entries, wherein a respective entry of the plurality of entries includes sequential state information for a respective user, the sequential state information for the respective entry identifying a respective preceding event associated with a respective preceding time and a respective subsequent event associated with a respective subsequent time that is subsequent to the respective preceding time; andinitiating aggregation of data in the first linear sequence table to obtain a quantity that corresponds to a number of entries that are associated with a particular preceding event and a particular subsequent event of preceding events and subsequent events of the plurality of entries.
