Abstract: A data management system for collecting data of users from sensors at an event. An event-specific token corresponding to the event attended by the users is generated, where the event-specific token includes event-specific signatures about the users attending the event, and the signature of the event venue or facility. The public data is sent to public storage as an aggregation of the collected data and tagged with the event-specific token. The public data is statistically analyzed to track interactions and assess risks of the user's potential infection of a communicable disease based on anomalous activity detected at the event, or based on the notifications from the event attendees, which are matched and validated anonymously using the event-specific tokens. Based on a result of the statistical analysis, an advisory alert is sent to the users to warn them of a level of risk of harm based on attendance of the event.

Abstract: An alarm log compression method, apparatus, system, and a storage medium are provided. The method includes: obtaining a historical alarm log set generated by a first network device; dividing the historical alarm log set into a plurality of historical alarm log subsets based on a generation time stamp of a historical alarm log in the historical alarm log set, where all historical alarm logs in each historical alarm log subset are consecutive in a time sequence; determining a correspondence between an alarm type in the historical alarm log set and the plurality of historical alarm log subsets; performing clustering processing on the alarm types in the historical alarm log set based on the correspondence, to generate at least one association rule; and compressing to-be-processed alarm logs based on the at least one association rule, to obtain an alarm log whose alarm type is a root cause alarm type.

Abstract: A data processing device determines, based on a plurality of logs of a same log type, a log template of the log type (i.e. a parsing rule), and extracts, based on the log template, variables of the plurality of logs to generate a structured log so that the parsing rule does not need to be manually set, and manual maintenance on the parsing rule is not needed. A data processing method includes obtaining a log set; determining that N logs in the log set belong to a first type; determining based on the N logs, a log template corresponding to the first type, where the log template corresponding to the first type is used to indicate a variable location of the N logs; and extracting based on the variable location, variables from one or more logs in the N logs to generate a structured log.

Abstract: A multi-version concurrency control method in a database and a database system is presented. The database system sets a data page link of a page, where the data page link includes a page pointer, and a page pointer is used to point to another version page prior to a last operation on the version page. In this way, when a page in the database is read, if a timestamp of a current version page is greater than a timestamp of a read transaction, page-level rollback may be directly performed according to a data page link of the page that is requested to read to roll back to a page that needs to be read, which facilitates queries for data on each version page in the database. Further, the database system may implement record rollback efficiently.
