Abstract: This application provides a trust computing method, a chip, and a server. The method includes the following steps: A trusted chip sends an authentication request to an authentication node, where the authentication request includes a request for the authentication node to perform trust authentication on the trusted chip. The trusted chip performs trust authentication on a component, where the component includes an input/output I/O unit and a storage unit.

Abstract: A database management system for performing a graph query based on one or more graph views of a relational-graph database is disclosed. The database management system is configured to determine a plurality of graph views of the relational-graph database based on one or more previous graph queries of the relational-graph database to obtain a plurality of candidate graph views of the relational-graph database. Moreover, the database management system is configured to store a subset of the plurality of candidate graph views of the relational-graph database and perform a graph query of the relational-graph database based on the subset of the plurality of candidate graph views of the relational-graph database. By means of the selected subset of the plurality of candidate graph views of the relational-graph database, the database management system advantageously allows increasing the processing speed of graph queries.

Abstract: A battery charging apparatus and method, a terminal, a power adapter, and a storage medium relate to the electronics field where the method includes detecting temperature of a charging path in a battery charging apparatus, and when a power adapter supplying charging power for the battery charging apparatus works in a first working mode and a detected largest temperature value is greater than or equal to a preset threshold, instructing the power adapter to switch to a second working mode, decoupling a charging path corresponding to the first working mode, and coupling a charging path corresponding to the second working mode. This reduces impact of local heat accumulation on device performance during charging of a terminal battery, lengthens a device life span, and improves user experience.

Abstract: A compilation method includes obtaining a source program code. The source program code includes a first function in a first language code and a second function in a second language code. The first language code is a native language. The second language code is a non-native language. The method also includes generating a third language code based on the source program code. The third language code includes a third function, a fourth function and a fifth function. The third function is generated based on the first function. The fourth function is generated based on the second function. The fifth function is generated based on the first function and the second function. Executing the third function invokes the fourth function via the fifth function.
