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: 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.

Abstract: The present invention relates to a base station, a small cell, and a method for scheduling a communications link resources. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.
