  • Publication number: 20210209004
    Abstract: Functional verification of a new database feature is provided. A set of SQL query seeds are evolved using information contained in a knowledge map that was generated based on a real SQL query workload of an entity corresponding to a database. Real SQL queries are identified in the database that are similar to the evolved set of sample SQL query seeds. A new feature to be implemented in the database is injected into the real SQL queries that are similar to the evolved set of sample SQL query seeds. Multiple runtime access paths are generated for each of the real SQL queries injected with the new feature for output cross validation. Each of the real SQL queries injected with the new feature is run in a test environment using each of the multiple runtime access paths corresponding to a real SQL query injected with the new feature for functional verification.

  • Patent number: 10939462
    Abstract: Embodiments of the present invention propose a D2D communications method, apparatus, and system. In the solution, a D2D SPS available period in which a first terminal is capable of using a D2D SPS resource is greater than one SC period. Therefore, in the D2D SPS available period, the first terminal needs to determine the D2D SPS resource only one time, and a second terminal also needs to decode SCI only one time to determine the D2D SPS resource. In this way, the first terminal does not need to determine a D2D SPS resource in each SC period, and the second terminal also does not need to decode SCI in each SC period to determine the D2D SPS resource. Therefore, D2D communication efficiency is improved.
