Abstract: A radiator sharing antenna and mobile terminal including the radiator sharing antenna includes a radiator divided into a first sub-radiator and a second sub-radiator by a gap, a first feeding point, and a second feeding point. A radio frequency signal is fed through the first feeding point on the first sub-radiator, and a radio frequency signal is fed through the second feeding point on the second sub-radiator. The radiator sharing antenna is adapted to generate a plurality of antenna operating bands through the resonance generated by the first sub-radiator and the second sub-radiator and the parasitic resonance generated through mutual influence between the first sub-radiator and the second sub-radiator.

Abstract: Disclosed is a method for estimating database management system performance, in which a performance change ratio of a DBMS can be determined once a first knob group, a second knob group, and a data volume of active data in data managed by the DBMS are obtained, without actually configuring the second knob group in the DBMS, executing a job by the DBMS, and then observing the execution. In other words, the performance change ratio of the DBMS can be estimated without interacting with the DBMS. DBMS security can be ensured, performance measurement approaches are provided for self-tuning and self-management of the DBMS, and reliable and stable running of the DBMS is ensured.
